WINDOWS 95/ NT HOST ADAPTER DRIVERS (SCSI MINIPORTS)
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

   What is a SCSI miniport?  A SCSI miniport is a device driver that controls
   your SCSI host adapter.  For example, if you are running Windows 95 with
   an Adaptec AHA-2940, the miniport driver you are using is named
   aic78xx.mpd.  Windows 95 and NT come with embedded drivers for most of
   Adaptecs host adapters. For those host adapter drivers not yet embedded or
   that have changed, we've included them on the "Adaptec EZ-SCSI Setup and
   Drivers Installation Disk" CD-ROM version of EZ-SCSI only.  The readme.txt
   on the setup disk contains additonal information on installation of miniports.

   For other SCSI host adapters not included on our floppy,
   additional miniport drivers can be found at one of the following
   locations:

DOS / WINDOWS 3.1/3.11 HOST ADAPTER DRIVERS (ASPI MANAGERS)
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

   Under DOS or Windows 3.1/3.11, EZ-SCSI installs drivers
   (also called ASPI Managers) to support Adaptec SCSI host adapters as
   specified in the list below. Following this list are troubleshooting
   tips for the drivers. If you installed EZ-SCSI from Windows 3.1x,
   an online help file about these drivers and the other drivers in EZ-SCSI
   was also installed. To view this select the Device Driver Reference icon.

Troubleshooting Tips
====================

ASPI8DOS.SYS
------------

   ASPI8DOS.SYS is Adaptec's ASPI manager for AIC-7850/7855/7870 based
   PCI SCSI host adapters.  Running Adaptec EZ-SCSI will automatically
   detect which host adapter you have installed, which ASPI manager needs
   to be loaded, and what the correct command line switches are.

   o  If you have an Adaptec PCI SCSI host adapter installed in your system,
      and you have EMM386.EXE loaded from MS-DOS versions up to 6.2, your
      system might hang if loading the ASPI manager after EMM386.EXE.  This
      has been fixed in the EMM386.EXE that ships with MS-DOS 6.22 and
      later.  If you experience this problem, you will either need to load
      ASPI8DOS.SYS before EMM386.EXE, or upgrade to MS-DOS 6.22 or later.
      If the ASPI manager detects a conflict, a message will be shown
      explaining how to work around the problem.  Other ASPI modules
      (e.g. ASPICD.SYS) can continue to be loaded high.

   o  There are several techniques for a driver to determine if its PCI SCSI
      host adapter is installed in your system.  ASPI8DOS.SYS will determine
      which is the best method, and has been written to work around the
      EMM386.EXE problems discussed above.  There are three command line
      switches you can use to force the ASPI manager to use a specific
      method.  These are:

        /MB - This command line switch will force the driver to use the
              PCI BIOS calls (INT 1Ah) to scan for PCI SCSI host
              adapters.
        /M1 - This command line switch will force the driver to use the
              "Mechanism 1" method for scanning for PCI SCSI host
              adapters.
        /M2 - This command line switch will force the driver to use the
              "Mechanism 2" method for scanning for PCI SCSI host
              adapters.

      For example, if you want to force the ASPI manager to find your PCI
      SCSI host adapter using PCI motherboard BIOS calls, your CONFIG.SYS
      would be:

        DEVICE=C:\SCSI\ASPI8DOS.SYS /D /MB

      NOTE:  Most PCI systems do not support all three methods for scanning
             for PCI cards.  It is recommended that you let the ASPI manager
             determine which method is suitable.

   o  If you would like ASPI8DOS.SYS NOT to reset the SCSI bus, during
      driver initialization, you can use the /NORST command line switch.
      For example:

        DEVICE=C:\SCSI\ASPI8DOS.SYS /D /NORST

      If you would like ASPI8DOS.SYS to always reset the SCSI bus, during
      driver initialization, you can use the /RESET command line switch.
      For example:

        DEVICE=C:\SCSI\ASPI8DOS.SYS /D /RESET

   o If there are more host adapters that ASPI8DOS can support, ASPI8DOS will display "Not enough
     memory for all host adapters". In this case, the user should manually add more lines of
     "DEVICE=ASPI8DOS.SYS" to CONFIG.SYS to support the extra host adapters. EZ-SCSI only installs  one entry in config.sys for ASPI8DOS.SYS.

32-BIT SUPPORT FOR WINDOWS 3.1/3.11
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

   Adaptec EZ-SCSI includes 32-Bit Disk Access support for Windows 3.1,
   Windows 3.11, and Windows for Workgroups 3.11.  To enable this support,
   simply run the "32-Bit Disk Access" utility (FASTSCSI.EXE), and follow
   the instructions.  Please note the following:

   o  Our 32-Bit Disk Access device drivers only support Adaptec's bus-
      mastering line of SCSI host adapters and Adaptec's AIC-6360/6370 based
      SCSI host adapters.  These host adapters use the following ASPI
      managers:

      ASPI2DOS.SYS
      ASPI4DOS.SYS
      ASPI7DOS.SYS
      ASPI8DOS.SYS
      ASPIEDOS.SYS
      MCAM18XX.SYS

      If your host adapter does not use one of these ASPI managers, our
      32-Bit Disk Access utility will still allow you to enable or disable
      SCSI write caching.

   o  If you are running Windows for Workgroups 3.11, and you are not able
      to get 32-Bit File Access to work properly, the following comes from
      Microsoft's Windows for Workgroups resource kit:

      "32-bit File Access will not enable on a drive on which there are
      open files during the initialization process of 32-bit File Access.
      Because of this, 32-bit file access cannot be enabled through the
      Control Panel Virtual Memory dialog when using a temporary swap file.
      The temporary swap file is opened before 32-bit File Access
      initializes and 32-bit File Access will not be able to enable on the
      drive where the temporary swap file is located.  There normally should
      not be any open files at the time when 32-bit File Access is
      initializing.  If there are open files, they are probably the result
      of some real mode TSR or a 3rd-party VxD."

   o  When 32-Bit Disk Access is enabled, you need to have the latest
      WINASPI.DLL file in your Windows' SYSTEM subdirectory.  If an older
      revision is being used, you will experience protection faults when
      running "ASPI for Windows" applications.  EZ-SCSI 3.11 (and later)
      will automatically install the correct WINASPI.DLL file.  There are,
      however, a few older packages that install the older WINASPI.DLL file.
      If you are experiencing protection faults, while running "ASPI for
      Windows" applications, you should check the date of WINASPI.DLL in
      your Windows' SYSTEM subdirectory.  If it is dated 1995 or later, you
      have the correct file.

   o  32-Bit Disk Access, in general, does not significantly improve
      performance under Windows 3.1 or Windows 3.11.  To get optimal disk
      performance, you should use Windows for Workgroups 3.11 which, in
      addition to 32-Bit Disk Access, includes support for 32-Bit File
      Access.  We are seeing the larger performance gains by enabling 32-Bit
      Disk Access, 32-Bit File Access, and SCSI write caching.

   o  Our 32-Bit Disk Access driver cannot be used if you are also using our
      SCSI Power Management driver.  If you attempt to load both drivers, an
      appropriate error message will appear when you run Windows.  If you
      encounter this message, and if you prefer 32-Bit Disk Access over SCSI
      Power Management, simply run Adaptec's 32-Bit Disk Access utility and
      select the "Install" option.  It will detect the conflict and remove
      the SCSI power management device driver.

   o  32-Bit Disk Access only supports drives under BIOS control (INT 13h
      drives).  This does NOT include drives under the control of
      ASPIDISK.SYS.  Most of our SCSI host adapters allow you to have up to
      8 SCSI drives under BIOS control.

   o  There is a known problem in Windows 3.1 and Windows 3.11 (does not
      affect Windows for Workgroups 3.11) in that its 32-Bit Disk Access
      solution only supports up to two hard drives.  For example, if you
      have three hard drives under BIOS control, only the first two would
      be under 32-Bit Disk Access.  If you encounter this situation, you
      can upgrade to Windows for Workgroups 3.11 which does not exhibit
      this limitation.

   o  Adaptec's 32-Bit Disk Access utility provides an uninstall option that
      will remove our 32-Bit device drivers.  If you would like to manually
      remove the drivers, remove the following entries from the [386Enh]
      section of your SYSTEM.INI file:

      device=fastscsi.386
      device=aha1540.386
      device=aha1740.386
      device=aic7770.386
      device=aic7870.386
      device=aic6x60.386
      device=aha2920.386

      (NOTE:  Not all of these drivers will be present in your SYSTEM.INI
      file.  Depends on what type of host adapter you have.)

   o  Enabling SCSI write caching can improve the overall performance of
      your system.  Many SCSI hard drives ship factory default with SCSI
      write caching disabled.  Our 32-Bit Disk Access utility will allow
      you to enable or disable SCSI write caching on a per device basis.
      We have found a few older drives causing system hangs, under intense
      disk I/O, when write caching is enabled.  In the unlikely event that
      you encounter this situation, you can disable SCSI write caching at
      any time by running our 32-Bit Disk Access utility.

   o  On some systems, when you enable 32-Bit Disk Access, Windows' Control
      Panel incorrectly loads the IDE 32-Bit Disk Access driver even if you
      only have SCSI disk drives.  This will typically result in an error
      message, while loading Windows, similar to the following:

      "The Microsoft Windows 32-bit disk driver (WDCTRL) cannot be
      loaded on this computer because of interrupt conflicts."

      If you encounter this, simply remove the line "device=*wdctrl" from
      the [386Enh] section of your SYSTEM.INI file.  Another option is to
      run our 32-Bit Disk Access utility.  It will detect that your
      configuration is incorrectly loading the IDE device driver and ask if
      you would like us to remove it.

   o  For the technical user:  If you select to turn on SCSI write caching,
      we will also turn on the AWRE (Automatic Write Reallocation Enabled)
      bit in the Read/Write Error Recovery Page.  If you select to turn off
      SCSI write caching, the AWRE bit is set back to the factory default
      setting (some drives ship factory default with AWRE set).

   o  If you have an AVA-2825 or AHA-1520A/1522A, with BIOS support for
      floptical drives enabled, and you have a floptical drive connected
      to your system, 32-Bit Disk Access is not supported under Windows
      3.1/3.11.

HARD DISK SUPPORT
=-=-=-=-=-=-=-=-=

Windows 95
----------

   Windows 95 includes built-in support for SCSI hard drives.  If you attach
   a new, unformatted, drive to your SCSI host adapter, you will need to
   partition and format the media before you can use it.  You can follow
   these steps:

   1.)  Run Device Manager.  You can do this by moving the mouse pointer
        over "My Computer," clicking the right mouse button, and selecting
        the "Properties" menu option.
   2.)  Select the "Device Manager" option.
   3.)  Expand the "Disk drives" tree to view your SCSI hard drives.
   4.)  Double-click on your newly added hard drive.
   5.)  Select the "Settings" option.
   6.)  If the "Int 13 unit" option is not turned on, then turn it on
        and select OK.  Reboot your system.
   7.)  Open up a DOS session (MS-DOS prompt).
   8.)  Run FDISK to partition your new drive as you desire.
   9.)  Reboot your operating system.
   10.) When Windows 95 comes back up, double-click on "My Computer."
   11.) Move the mouse pointer over your new drive letter(s), click the right
        mouse button, and then select the "Format..." option.
   12.) Follow the instructions to format your media.

   NOTE:  Under many configurations, steps 1-6 are not required as Windows
          95 may have already marked your new disk drive as an "Int 13
          unit."  We still recommend that you take these steps to ensure
          that your system is properly configured.

Windows NT
----------

   Windows NT includes built-in support for SCSI hard drives.  If you attach
   a new, unformatted, drive to your SCSI host adapter, you will need to
   partition and format the media before you can use it.  You can format
   your new drive, under NT, by running the "Disk Administrator" utility
   that ships with the operating system.

Windows 3.1/3.11 and DOS
------------------------

   DOS and Windows 3.1x include built-in support for SCSI hard drives if your
   new drive is under BIOS control (e.g. you booted from it).  Please refer
   to your host adapter documentation to learn more about whether or not
   your SCSI host adapter includes an on-board ROM BIOS.  In this case, you
   can follow these steps:

   1.)  Boot to DOS.
   2.)  Run FDISK to partition your new drive as you desire.
   3.)  Reboot your operating system.
   4.)  Run FORMAT on your newly created drive letter(s)

   If your new SCSI hard drive is not under BIOS control, you can follow
   these steps:

   1.)  If running Windows 3.1x, install Adaptec EZ-SCSI for Windows 3.1x
          - Insert the Adaptec EZ-SCSI Setup Disk
          - Run SETUP.EXE
   2.)  If running DOS, install Adaptec EZ-SCSI for DOS
          - Insert the Adaptec EZ-SCSI Setup Disk
          - Run DOSINST.BAT
   3.)  After installing either Adaptec EZ-SCSI for DOS/Windows, reboot
        your system.
   4.)  If you are running DOS, run AFDISK.EXE which is located in your
        Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI).  If you are running
        Windows, you can use WINPART.EXE which is a Windows 3.1x
        partitioning utility.
   5.)  Partition your new media as you desire.
   6.)  Reboot your operating system.
   7.)  At this point, your new drive is under ASPIDISK.SYS control
        (Adaptec's disk driver for DOS).
   8.)  Although optional, we recommend that you run DOS FORMAT on your
        new drive letter(s) so that the drive can be scanned for defects.


=-=-=-=-=-=-=-=-=-=-=-=
REMOVABLE MEDIA SUPPORT
=-=-=-=-=-=-=-=-=-=-=-=

Windows 95
----------

   There are a number of ways to prepare your removable media for use under
   Windows 95.

   Windows 95, by default, will allocate one drive letter for your removable
   media device.  You can see the icon by double-clicking on "My Computer"
   and seeing the "Removable Disk" text just below the drive's icon.  If
   you wish to treat your removable media as one large floppy, simply
   insert the media into the drive and double-click on the icon.  Windows
   95 will automatically detect that the media is unformatted and ask you
   if you would like to format the media.

   Windows 95 also allows you to use partitioned removable media.  For
   example, if you have a 1 GByte removable cartridge, you might want to
   partition the media into two 512 MByte partitions.  To create a
   partitioned removable media, you can follow these steps.

   1.)  Run Device Manager.  You can do this by moving the mouse pointer
        over "My Computer," clicking the right mouse button, and selecting
        the "Properties" menu option.
   2.)  Select the "Device Manager" option.
   3.)  Expand the "Disk drives" tree to view your SCSI removable hard drive.
   4.)  Double-click on your newly added removable hard drive.
   5.)  Select the "Settings" option.
   6.)  If the "Int 13 unit" option is not turned on, then turn it on
        and select OK.  The "Removable" option should also be set.  Reboot
        your system.
   7.)  Open up a DOS session (MS-DOS prompt).
   8.)  Run FDISK to partition your removable media as you desire.
   9.)  Reboot your operating system.
   10.) If you want to reserve multiple drive letters for your removable
        media drive (e.g. multiple partitions), follow the next steps,
        otherwise, skip to step #17
   11.) Run Device Manager.  You can do this by moving the mouse pointer
        over "My Computer," clicking the right mouse button, and selecting
        the "Properties" menu option.
   12.) Select the "Device Manager" option.
   13.) Expand the "Disk drives" tree to view your SCSI removable hard drive.
   14.) Double-click on your newly added removable hard drive.
   15.) Select the "Settings" option.
   16.) In the "Reserved Drive Letters" area, you can select the starting
        and ending drive letters for your removable media device.  Save
        settings and reboot your system.
   17.) When Windows 95 comes back up, double-click on "My Computer."
   18.) Move the mouse pointer over your new drive, click the right mouse
        button, and then select the "Format..." option.
   19.) Follow the instructions to format your media.

   NOTE:  Under many configurations, steps 1-6 are not required as Windows
          95 may have already marked your new disk drive as an "Int 13
          unit."  We still recommend that you take these steps to ensure
          that your system is properly configured.

   Below is additional information you may find useful:

   o  We recommend that you boot Windows 95 without a DOS removable media
      device driver (e.g. ASPIDISK.SYS).  You can comment out such entries
      from your CONFIG.SYS and then reboot.  We have seen Windows 95
      incorrectly create two drive letters for the same device when a
      DOS removable media driver is resident.  In addition, we have seen
      some configurations where Windows 95 wouldn't allow us to set the
      starting and ending drive letters when a DOS removable media device
      driver is resident.

Windows NT
----------

   Please consult your Windows NT documentation on using removable media
   with Windows NT.

Windows 3.1/3.11 and DOS
------------------------

   To prepare your removable media for use under Windows 3.1/3.11 and DOS,
   you can follow these steps.

   1.)  If running Windows 3.1x, and your CD-ROM is visible in File Manager,
        install Adaptec EZ-SCSI for Windows 3.1x by:
          - Insert the Adaptec EZ-SCSI Setup Disk
          - Run SETUP.EXE
   2.)  If running DOS, or you dont have a CD-ROM drive,
        or you are using it for the first time install Adaptec EZ-SCSI for DOS
          - Insert the Adaptec EZ-SCSI Setup Disk
          - Run DOSINST.BAT
   3.)  After installing either Adaptec EZ-SCSI for DOS/Windows, reboot
        your system.
   4.)  If you are running DOS, run AFDISK.EXE which is located in your
        Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI).  If you installed using SETUP.EXE
        in Windows, you can use WINPART.EXE which is a Windows 3.1x
        partitioning utility.
   5.)  Partition your new media as you desire.
   6.)  Reboot your operating system.
   7.)  At this point, your new drive is under ASPIDISK.SYS control
        (Adaptec's disk driver for DOS).
   8.)  Although optional, we recommend that you run DOS FORMAT on your
        new drive letter(s) so that the drive can be scanned for defects.

   Below is additional information you may find useful:

   o  Adaptec EZ-SCSI supports both 512 byte/sector media and 1024 byte/
      sector media.

   o  If you would like to reserve multiple drive letters for your removable
      media, you can use the /r command line switch.  For example, if you
      would like ASPIDISK.SYS to reserve two drive letters for your removable
      media, you would have the following in your CONFIG.SYS:

         device=c:\scsi\aspidisk.sys /d /r2

   o  Support for the Panasonic PD drive is also included.  Note that you
      should leave this device jumpered in its default two LUN mode.

CD-ROM SUPPORT
=-=-=-=-=-=-=-=

Windows 95
----------

   Windows 95 includes built-in support for SCSI-2 CD-ROM drives and some
   SCSI-1 devices.  If your host adapter already has its miniport loaded,
   Windows 95 will automatically detect and support your SCSI CD-ROM drive.

   o  We recommend that you boot Windows 95 without a DOS CD-ROM device
      driver (e.g. ASPICD.SYS).  You can comment out such entries from your
      CONFIG.SYS and then reboot.  We have seen Windows 95 incorrectly create
      two drive letters for the same device when a DOS CD-ROM driver is
      resident.

Windows NT
----------

   Please consult your Windows NT documentation on using CD-ROM drives with
   Windows NT.

Windows 3.1/3.11 and DOS
------------------------

   Adaptec's CD-ROM driver for DOS/Windows, ASPICD.SYS, has been written to
   support any SCSI-2 CD-ROM drive and most SCSI-1 CD-ROM drives.  Simply
   run Adaptec EZ-SCSI and the correct additions will be made to your
   CONFIG.SYS and AUTOEXEC.BAT.

   Adaptec EZ-SCSI has been tested with CD-ROM drives from the following
   vendors:

         AIWA        Compaq      Chinon      Denon       Goldstar
         Hitachi     IBM         LMS         Matsushita  NEC
         Panasonic   Nakamichi   Philips     Pioneer     Plasmon Data
         Plextor     Ricoh       Sanyo       Sony        TEAC
         Texel       Toshiba     Yamaha

   Below is additional information you may find useful:

   o  The following drives do not directly support Photo CD:

        Chinon         CDS 431
        Denon          DRD 253
        LMS (Philips)  CM 214
        NEC            CDR 72
        NEC            CDR 74   (NOTE: 74-1 and 84-1 do support single-
        NEC            CDR 84          session Photo CD)

      By adding /XAEMUL to the ASPICD.SYS command line, in your CONFIG.SYS,
      we will emulate support for single-session Photo CD on these drives.

   o  The following drives do not support parity:

        NEC CDR 38
        NEC CDR 55
        NEC CDR 72
        NEC CDR 73
        NEC CDR 74 (NOTE: 74-1 and 84-1 do support SCSI parity)
        NEC CDR 84
        NEC CDR 210 (NOTE: 210P does support parity)

      Please consult your host adapter documentation on how to disable parity
      support on your SCSI host adapter.

   o  The following jukebox CD-ROM drives are fully supported:

        Nakamichi MBR-7
        Pioneer   DRM 600
        Pioneer   DRM 604X
        Pioneer   DRM 624X

      A drive letter will be assigned for each CD.

   o  Some older SCSI CD-ROM drives do not support synchronous negotiation
      properly.  If you encounter problems using your CD-ROM drive, try
      disabling synchronous negotiation.  Please refer to your host adapter
      documentation on how to do this.

   o  In rare circumstances, you may encounter problems with Windows 3.x and
      DOS reading your CD-ROM drive.
      For example, you change the contents of the CD-ROM drive, but when you run
      DIR, the contents of the previous CD is displayed instead of the new CD's.
      Or you may see multiple drive letters assigned to your single CD-ROM drive.
      One solution is to add the /NOLUN switch to the aspicd.sys line in config.sys.
      We have seen the former problem with the Sony 55s - an older double speed
      CD-ROM drive, and the latter problem with an older SCSI1 Panasonic drive.
      By adding the /NOLUN switch, you will however loose support
      for any CD Changers or PD drives that you also have connected to your PC.

Windows 95
----------

   NOTE:  Adaptec Backup is only shipped with the full version of Adaptec
          EZ-SCSI.  This does not include the 'L' license version (e.g.
          4.00L).

   Adaptec EZ-SCSI includes a full-featured Backup application designed
   for Windows 95.  Adaptec Backup can backup to a SCSI tape drive, and if
   you do not have a SCSI tape drive attached, it can also backup to your hard
   drive or to a removable hard drive. Adaptec EZ-SCSI has
   been tested for compatibility with the following SCSI tape drives:

   (1) Adaptec Backup does not support tape linking on these SCSI tape
       drives.  Tape linking allows you to continue a backup across two or
       more tapes.

   (2) On this tape drive, restores and compares will be slow to start.
       This does not affect backups.

   (3) On this tape drive, only a single Backup set is supported.

   Please note the following:

   o  Unerase and Rename Tape are not supported by SCSI tape drives so these
      menu options will be grayed out when running Adaptec Backup.

   o  Doing a Secure Erase on a DAT drive will usually take several hours
      to complete.  During this process, you will not be able to exit the
      application until the Secure Erase is complete.

   o  If you are using a DAT tape that was previously formatted by a
      different tape backup application, Adaptec Backup may take up to 5
      minutes before it can initialize the tape.  You should format the
      tape with Adaptec Backup once the initialization is complete.

   o  If you are encountering problems backing up to a hard disk, network drive,
      or removable media drive - make sure that there is no SCSI tape drive
      attached to your system. Backup to a hard disk, network drive,
      or removable media drive is only supported when there is no SCSI tape
      drive attached.

   o  Adaptec backup does not support backing up a floppy to a tapedrive, or
      backing up from a network drive to a tape drive.

Windows NT
----------

   Adaptec EZ-SCSI does not include a tape backup package for Windows NT.
   Please consult your Windows NT documentation for additional information
   on the SCSI tape backup application that ships with the operating system.
   In addition, if you have the CD-ROM version of Adaptec EZ-SCSI, you can
   view Adaptec's 3rd party directory for a list of companies who provide SCSI
   tape backup support.  Simply double click on the file 96dir.hlp in the \ACAP
   directory of your Adaptec EZ-SCSI CD-ROM.

Windows 3.1/3.11 and DOS
------------------------

   Adaptec EZ-SCSI does not include a tape backup package for DOS or Windows
   3.1x.  If you have the CD-ROM version of Adaptec EZ-SCSI, you can view
   Adaptec's 3rd party catalog for a list of companies who provide SCSI tape
   backup support.  Simply double click on the file 96dir.hlp in the \ACAP
   directory of your Adaptec EZ-SCSI CD-ROM.

CD RECORDABLE SUPPORT
=-=-=-=-=-=-=-=-=-=-=

Windows 95
----------

   NOTE:  CD Writer is only shipped with the full version of Adaptec EZ-SCSI.
          This does not include the 'L' license version (e.g. 4.00L).

   When using a CD Recordable drive, you need an application to write to the
   CD.  It is also desirable to have a device driver that assigns a drive
   letter to the CD Recordable so that you can also read files from the drive
   in the standard way.  If your CD Recordable supports audio, this would
   also allow you to play audio CDs.

   Most CD Recordable devices today report themselves as a Write Once Read
   Many (WORM) device.  Some of the newer CD Recordable devices report
   themselves as a standard CD-ROM drive.  If your device is of the latter
   type, Windows 95 should automatically assign a drive letter to your
   drive.  If your device reports itself as a WORM device, then you will
   need to load our real mode CD-ROM driver and Microsoft's CD-ROM extensions
   (MSCDEX.EXE).  The simplest way to load the real mode drivers is to exit
   Windows 95 back to DOS and run Adaptec EZ-SCSI for DOS (discussed
   earlier).  Once these changes are made, you can reboot back into Windows
   95 and have a drive letter assigned to your CD Recordable drive.  Windows
   95 will mark your CD Recordable device as "Unknown."  This is normal.

   In addition to reading from a device, you will need the ability to create
   a CD-ROM.  Adaptec EZ-SCSI includes two applications that allow you to
   fully utilize your CD Recordable drive:

      CD Writer  Allows you to copy files from your hard drive to your
                 CD Recordable drive.

      CD Copier  The "CD Copier" application allows you to backup CDs from
                 your source SCSI-2 CD-ROM drive to one of the destination CD
                 Recordable devices listed below.  You can backup audio CDs
                 and data mode 1 CDs (most CDs), but not photo CDs or CD-i
                 CDs. You cannot copy from EIDE CD-ROM drives.

   The list of CD Recordable drives that Adaptec CD Writer supports are:

   (1) Audio copy only works on this CD Recorder if the source CD can read
       audio at 2x or greater such as a Sony 561.

   (2) With the HP C4324/C4325 (4020i) and the Philips CDD2000, you will need v1.20
       or later of their firmware.  You can use the SCSI Explorer to determine the
       revision level of your unit.

   (3) "After a successful simulated copy do a real copy" does not work on this drive.
       You should do a simulated copy by leaving the "Simulate Only" checkbox checked.
       If this is successful, uncheck the "Simulate Only" checkbox and run copy again.

   WARNING: If your CD-Recordable drive is one of the ones that report
   themselves as a standard CD-ROM drive, you will need to turn off
   Auto Insert Notification for it while recording discs.
   To do this:
   1.)  Run Device Manager.  You can do this by moving the mouse pointer
        over "My Computer," clicking the right mouse button, and selecting
        the "Properties" menu option.
   2.)  Select the "Device Manager" option.
   3.)  Expand the "CDROM" tree to view your CDROM drives.
   4.)  Double-click on your CD-Recorder.
   5.)  Select the "Settings" option.
   6.)  Remove the check box from the "Auto insert notification" field.
   7.)  Reboot your system.


   Because CD-ROM drives vary in how well they support the SCSI specification,
   we have created a table below which contains a list of the CD-ROM players
   that we have successfully made copies of CDs from, and notes on any
   problems we encountered.  If your drive is not on this list, but is a
   derivative of one of these drives, or is fully SCSI-2 compliant, you
   should be able to use it as a source to backup data CDs from.  We also note
   in this table those drives which you can use as a source to backup an audio
   CD.  Reading of audio tracks is not a SCSI-2 defined function, and is
   implemented differently by those newer drives that actually support this
   feature.

   (1)  To date, the NEC drives we have tested read audio too slow to make a
        successful copy.

   (2)  This drive sometimes has problems reading the last blocks of a CD
        made by a CD Recorder (e.g. a copy of a copy), and has resulted in
        CDs being ruined.  If a SCSI command takes too long, Windows 95 and
        Windows NT will reset the SCSI bus and SCSI devices, thereby halting
        the writing process on the CD Recorder resulting in a ruined disc.

   (3)  In our testing of this device, there is a background hiss when
        copying audio CDs.

   (4)  We have seen some read positioning errors on this device causing
        audio copying to sometimes fail.

   Additional information on CD-ROM readers:

     o We do not support copying CDs from a Pioneer DRM-604X CD-ROM drive.

     o The Adaptec CD Copier runs best if you do not have a dirty or
       scratched source CD as timeouts can occur given this condition.

   If you are familiar with CD-Recorder technology, you already know that
   once you start writing a track, you cannot stop until that track has been
   completely written.  The write process must be uninterrupted otherwise the
   blank CD will be ruined.

   To reduce the need for a large amount of free space on your hard disk,
   Adaptec CD Copier does on the fly recording (i.e. it reads and writes
   directly to and from the CD player and recorder without hard disk
   buffering).  It is therefore very important that we can read data from
   your CD player at least as fast as we can write to your CD-Recorder.  By
   default, we determine the speed of your CD player, and then set the CD
   Recorder speed to be slower than this.  You can view the speed that we
   set the CD-Recorder to in the text shown in the status window "Now copying
   CD at 2x ...".  If you feel the speed we choose for the CD-Recorder is too
   conservative, you can set it to a higher one using the Advanced tab.
   Before you choose a faster speed, please make sure that the speed you pick
   is not faster than the speed of the CD player.  To check for this with
   data CDs, place a data CD like your Adaptec EZ-SCSI CD into your CD player,
   and run Adaptec SCSIBench.  Choose your player and start a 64K sequential
   read benchmark on it.  To set your recorder to 2x (i.e. double speed) the
   transfer rate as displayed by Adaptec SCSIBench on the right hand side
   should be at least 300 KB/sec.  We do not provide you with a method to
   test the speed when reading an audio CD.  Most of the drives that we have
   tested, except for Sony, read audio at 1x.  Therefore you will not be able
   to make an audio backup with any CD Recorder that cannot be set to 1x.

   Most users will place their CD-ROM drive and CD-Recorder on the same host
   adapter.  That is how we test it here at Adaptec.  In order to achieve the
   performance that we desire, it is important that your CD-ROM drive NOT
   have excessive SCSI bus utilization.  Fortunately, most SCSI CD-ROM drives
   get on and off the bus very quickly and support SCSI disconnect.
   Unfortunately, a few do not and this can cause buffer underrun conditions.

   How do you test for this?  First off, make sure that you have SCSI dis-
   connection enabled at all times.  Windows 95 allows you to enable or
   disable it from the Device Manager.  Please leave it enabled.  Also, many
   SCSI host adapters allow you to change the settings via their configuration
   software (e.g. SCSISelect).  These will ship with disconnection enabled by
   default.  If you disabled disconnection, please turn disconnect back on
   before trying this software.   If you have a SCSI disk drive also hooked
   up to the same host adapter as the CD-ROM drive and CD-Recorder drive,
   you're ready to run our test.  Run Adaptec SCSIBench and do a 64K
   sequential read benchmark of your disk drive only.  You'll see a number
   appear, typically between 1 MByte/sec and 7 Mbytes/sec.  Now, insert a
   data CD into your CD-ROM drive.  Add it to your benchmark by clicking on
   its device name.  At this point, both devices are part of the benchmark.
   If you have a 3x CD-ROM drive, you will see that your CD-ROM drive is
   sustaining about 450 Kbytes/sec.  If you see that your disk drive's
   throughput has dropped dramatically down to about the same value (e.g. 450),
   then you probably have a CD-ROM drive that has excessive bus utilization.
   If you encounter this, you may need to set our CD Copier software for
   single speed copies (e.g. 1x).  We do not see this with many CD-ROM drives.

Windows NT
----------

   Most CD Recordable devices today report themselves as a Write Once Read
   Many (WORM) device.  Some of the newer CD Recordable devices report
   themselves as a standard CD-ROM drive.  If your device is of the latter
   type, Windows NT should automatically assign a drive letter to your
   drive.  If your device reports itself as a WORM device, then you will not
   be able to have a drive letter assigned to your drive.

   Adaptec CD Writer and Adaptec CD Copier are both supported under NT.
   See the discussion under Windows 95 above for additional details.

Windows 3.1/3.11 and DOS
------------------------

   Adaptec EZ-SCSI for Windows 3.1/3.11 and DOS does not include software
   to allow you to write your own CDs.  Adaptec's CD-ROM driver, ASPICD.SYS,
   does allow you to assign a drive letter to your CD Recordable drive.
   Third party applications, such as Incat's Easy CD Pro, allow you to master
   CDs under Windows 3.1/3.11.

   -------------------------------
   You may retrieve the drivers for NT from the same sources as
   mentioned under Windows 95.

   If after you install the HP software and drivers for their
   scanners, you find that your EZ-SCSI applications do not work.
   Please re-install EZ-SCSI. The problem is usually due to HP
   installing an older ASPI layer for NT than that which comes
   with EZ-SCSI.


   Other Scanners

   Contact your scanner company for information on Windows NT support.

Windows 3.1/3.11 and DOS
------------------------

   Hewlett-Packard Scanner Support
   -------------------------------

   Hewlett-Packard's driver for HP ScanJet II scanners is included with
   Adaptec EZ-SCSI.  This driver is named SJIIX.SYS and is designed to
   function with Adaptec's ASPI managers.

   Installation of the driver is easy.  Simply run Adaptec EZ-SCSI.  Adaptec
   EZ-SCSI automatically detects your HP scanner and installs SJIIX.SYS into
   the appropriate section of your CONFIG.SYS file.  You can then install
   HP's DESKSCAN software if it is not already installed.

   Epson Scanner Support
   ---------------------

   To connect your PC system with the SCSI interface on an Epson scanner,
   first install an Adaptec SCSI Host Adapter interface board and EZ-SCSI
   software onto your PC system before loading the Epson Scanner Utility
   and TWAIN driver.  The Epson scanner TWAIN driver should be included
   with your Epson scanner.

   Other Scanners
   --------------

   Most scanners support the ASPI interface.  Contact your scanner vendor
   to determine if their scanner and software support ASPI.

WINDOWS 95/NT GENERAL TROUBLESHOOTING
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

ASPI Layer
==========
There is a known problem with the Service Pack 4 release of Windows NT 3.51
which prevents Adaptec EZ-SCSI from automatically updating the ASPI
layer.  The new versions of the ASPI files will be copied to your system
during EZ-SCSI installation, but they will have incorrect filenames.  If you
are running under Windows NT 3.51 Service Pack 4 while installing Adaptec
EZ-SCSI and want to update your system to use the new ASPI layer, you
must rename these files to their correct filenames as listed below:

Incorrect Filename      Correct Filename    Location on System
---------------------------------------------------------------
WINASPI.ADP             WINASPI.DLL         C:\WINNT\SYSTEM\
WOWPOST.ADP             WOWPOST.EXE         C:\WINNT\SYSTEM\
WNASPI32.ADP            WNASPI32.DLL        C:\WINNT\SYSTEM32\
ASPI32.ADP              ASPI32.SYS          C:\WINNT\SYSTEM32\DRIVERS\

Once you have completed renaming these files reboot your system in order
for the new ASPI layer to take effect.



   o  Adaptec EZ-SCSI for Windows 95 requires that your miniport drivers
      (discussed earlier) are properly installed.  You can do this by moving
      the mouse pointer over "My Computer," clicking the right mouse button,
      and selecting the "Properties" menu option.  Find your SCSI host
      adapter(s), double-click on it, and then you can determine whether or
      not your miniport driver is properly installed.

   o  The Adaptec EZ-SCSI application, SCSI Explorer, displays a tree-view
      list of your SCSI host adapter(s) and all devices connected to it.
      The order which SCSI Explorer displays your SCSI host adapters may
      not be in the order you think it should be in.

      For example:

      You may have an Adaptec AHA-2940 PCI SCSI host adapter and an
      AHA-1542CP ISA SCSI host adapter in your system, and you are booting
      from the AHA-2940.  The AHA-2940 is considered to be host adapter #0
      while the AHA-1542CP is considered to be host adapter #1.  The SCSI
      Explorer may display the AHA-1542CP first in the tree-view list
      followed by the AHA-2940.  This ordering issue is the result of the
      manner in which the Adaptec miniports scan for SCSI host adapters.
      Adaptec SCSI Explorer will continue to work just fine.

   o  The Adaptec SCSI Interrogator, part of the SCSI Explorer, allows you
      to lock, unlock, or eject media from a removable media device.  Some
      SCSI devices do not support these commands.

   o  Under Windows NT, Adaptec SCSI Power Management and Drive Light do not
      support striped hard drives.

   o  Under Windows NT, Adaptec Drive Light does not monitor ASPI calls.
      For example, the icons in Drive Light will not flash when running
      Adaptec SCSIBench.  This is not a limitation if running under Windows
      95.

   o  Under Windows NT, SCSI tape drives will not appear under Drive Light
      unless you first load the SCSI tape driver that ships with Windows
      NT.  There are two steps you must do:

         1.)  Install the tape driver.  To install the tape driver, go to
              Windows NT Setup and choose "Options," choose "Add/Remove Tape
              Devices," choose "Add," select the appropriate tape drive
              model, and choose "Install."

         2.)  Reboot your system.

   o  When running Drive Light under Windows 95, you may notice that we
      flash your CD-ROM drive every few seconds, even though your CD-ROM
      drive's LED isn't flashing.  This is correct behavior.  Although the
      CD-ROM drive's LED doesn't flash, Windows 95 is checking the drive
      every few seconds to see if a media change has occurred.

   o  Adaptec EZ-SCSI applications (e.g. SCSI Explorer) do not support
      multiple LUNs.  If you have a multi-LUN device, you will only see
      LUN #0.

   o  If you are playing an Audio CD, and you try to access the CD-ROM drive
      through an ASPI application (e.g. SCSI Explorer), the audio may stop
      playing in order to service your I/O request.  This is normal
      behavior.

   o  Adaptec SCSIBench does not support benchmarking the Pioneer DR-124X
      CD-ROM drive.

   o  If you are running Adaptec SCSIBench under Windows 95, and it does not
      work with 64K transfers, but works with any other transfer size, you'll
      need to upgrade your miniport driver.  See the README.TXT file on the
      Adaptec EZ-SCSI Setup Disk (CD-ROM version only) for information
      on newer SCSI miniport drivers.

   o  We have seen one system running Windows 95, with a number of 16-bit
      Windows applications resident, generate a DDE error when the Adaptec
      EZ-SCSI installation attempts to add icons to your "Start" menu.  If
      you encounter this, please close all resident applications before
      installing Adaptec EZ-SCSI.

   o  When using ASPI under Windows 95, the ASPI layer will report your
      SCSI host adapter as SCSI ID #7, even if you've relocated it to a
      different ID.  We recommend that you leave your SCSI host adapter
      at the factory default setting of SCSI ID #7.

   o  We have found that the Philips CDD-521 and CDD-522 CD Recordable drives
      do not properly handle synchronous negotiation.  This can cause the
      device to not get recognized, or get incorrectly recognized, by the
      operating system.  If you are experiencing this problem, how you solve
      it depends on the SCSI host adapter you are using and whether you're
      running Windows 95 or Windows NT.

      For Windows 95, Adaptec EZ-SCSI will automatically disable synchronous
      negotiation for these devices on all of the host adapters except
      2920. Please see the 2920 section under Miniports on how to disable
      synchronous negotiation.
      If problems still persist, and if your host adapter allows you to disable
      synchronous negotiation (e.g.SCSISelect), use your host adapter application
      to disable synchronous negotiation.

      For Windows NT, it's a little more involved. If you have a 2920 please
      see the 2920 section under Miniports on how to disable synchronous negotiation.
      If the operating system does not correctly detect the device, and if your
      host adapter allows you to disable synchronous negotiation (e.g. SCSISelect),
      use your host adapter application to disable synchronous negotiation.
      If you have a 2920 please see the 2920 section under Miniports on how to disable
      synchronous negotiation. If your host adapter doesn't have such an application,
      you can follow these steps to disable synchronous mode for your entire
      host adapter.  There is no per device control.  Run REGEDT32.EXE and:

        1) Open \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
        2) Open the name of the particular miniport
        3) Create a key named Parameters
        4) Open Parameters and create a key named Device
        5) Open Device
        6) Add Value with the following information:
             Value Name:  DisableSynchronousTransfers
             Data Type:   REG_DWORD
             Value:       1



=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
WINDOWS 3.1x/DOS GENERAL TROUBLESHOOTING
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

   o  The ordering in which the Adaptec EZ-SCSI installer displays SCSI host
      adapters detected is dependent on a number of factors.  If you have
      multiple SCSI host adapters, and the ordering displayed is not as
      you would expect, do not be alarmed.  Adaptec EZ-SCSI will still
      properly edit your configuration files.

   o  SMARTDRV 5.0 (in MS-DOS 6.2, Windows for Workgroups 3.11) now includes
      caching for CD-ROM drives.  There is a problem with SMARTDRV in its
      support for XA formatted Compact Discs.  If you experience "Not Ready"
      errors, using SMARTDRV 5.0, add /E:2048 to your SMARTDRV command line.
      For example:

           C:\DOS\SMARTDRV /X /E:2048

   o  You should install Adaptec EZ-SCSI to a drive letter that exists at
      boot time.  This would NOT include RAM drives, network drives,
      removable drives, etc.

   o  We have seen at least one case where an unstable video driver would
      cause EZ-SCSI for Windows to hang during installation.  If you are
      experiencing similar problems, try using the standard VGA driver that
      comes with Windows.  If EZ-SCSI for Windows then installs properly,
      you may want to contact your video card company for updated drivers.

   o  In the unlikely event that you encounter a time-out failure when
      EZ-SCSI for Windows scans the SCSI bus, you should run EZ-SCSI for
      DOS first.  Let it modify your CONFIG.SYS to load the appropriate
      ASPI managers; reboot your system.  You should then be able to run
      EZ-SCSI for Windows.

   o  If you have an AHA-2740W/2742W or AHA-2940W (Wide SCSI Host
      Adapter), the SCSI Interrogator for Windows (SHOWSCSI.EXE) will only
      show icons for SCSI IDs 0-7.  You will not see IDs 8-15.

   o  The SCSI Power Management Utility requires that the following line
      be present in your SYSTEM.INI file under the [386Enh] section:

           device=VSCSIPWR.386

      The first time you run SCSI Power Management you will be prompted to
      install the above driver.  If you wish to disable the SCSI Power
      Management functions, you can remove this line from your SYSTEM.INI
      file in your WINDOWS subdirectory.

   o  An issue with EMM386.EXE from DOS 6.2, and earlier, can cause problems
      with PCI systems.  The HIGHSCAN option can overwrite the PCI BIOS area
      on some PCI systems, making the PCI BIOS detection useless.  If your
      Adaptec PCI SCSI host adapter is not detected, be sure to remove the
      HIGHSCAN option from EMM386.EXE in your CONFIG.SYS file.

   o  If you have a Trantor T160/T260 SCSI host adapter, EZ-SCSI will no
      longer scan for this adapter if you select the default installation
      option.  In this case, you will need to select the custom installation
      option, and manually select the adapter, to properly install Adaptec
      EZ-SCSI.

   o  The SCSI Power Management Utility is not compatible with the Trantor
      T160 and T260 SCSI Host Adapters.
