       2.0   Installation and Setup Instructions

             2.1   Step by step instructions for this code update

                   - Run the "IBM System x3755 Linux BIOS Update"
                     with the following command line:
                     
                        "./<update>.sh -s" where <update>.sh is the
                        downloaded update.

                     NOTE: The following message is shown on RedHat Enterprise Linux 3.0
                     and other distributions that do not install the compatibility libstdc++
                     library.
          
                        ./lflash: error while loading shared libraries:
                        libstdc++-libc6.1-1.so.2: cannot open shared object file:
                        No such file or directory.
                          
                     If the above message is shown, install the compat-libstdc++*.rpm that was
                     included on the distribution media.

                     NOTE: The following message is shown if the OSA Baseboard Management
                     Controller driver and IBM IPMI mapping layer are not installed.

                        Could not find IPMI driver.  Please check your OSA IPMI driver and IBM
                        mapping layer installation.
                        BIOS flash will proceed but VPD data will be inconsistent.

                     If the above message is shown, install the OSA BMC driver and IBM IPMI
                     mapping layer from the support web page.

             2.2   Step by step instructions for extracting the Linux update
                   files.

                   - Run the "IBM System x3755 Linux BIOS Update"
                     with the following command line:
                     
                        "./<update>.sh -x <path>" where <update>.sh is the
                        downloaded update and <path> is the path to which the
                        Linux update files will be extracted.
                        
                     NOTE: The following message is shown on RedHat Enterprise Linux 3.0
                     and other distributions that do not install the compatibility libstdc++
                     library.
          
                        ./lflash: error while loading shared libraries:
                        libstdc++-libc6.1-1.so.2: cannot open shared object file:
                        No such file or directory.
                          
                     If the above message is shown, install the compat-libstdc++*.rpm that was
                     included on the distribution media.

                     NOTE: The following message is shown if the OSA Baseboard Management
                     Controller driver and IBM IPMI mapping layer are not installed.

                        Could not find IPMI driver.  Please check your OSA IPMI driver and IBM
                        mapping layer installation.
                        BIOS flash will proceed but VPD data will be inconsistent.

                     If the above message is shown, install the OSA BMC driver and IBM IPMI
                     mapping layer from the support web page.
                        
                   - The files extracted are all the files that are necessary to 
                     perform a BIOS update under Linux.  Run "./lflash" from a
                     command line to update BIOS on 32-bit Linux or "./lflash64"
                     from a command line to update BIOS on 64-bit Linux.

             2.3   Step by step instructions for extracting the DOS update
                   files to diskette.

                   - Run the "IBM System x3755 Linux BIOS Update"
                     with the following command line:
                     
                        "./<update>.sh -xd <drive>" where <update>.sh is the
                        downloaded update and <drive> is the path to which the
                        Linux update files will be extracted.  If <drive> is
                        omitted, /dev/fd0 is assumed.

                     NOTE: The following message is shown on RedHat Enterprise Linux 3.0
                     and other distributions that do not install the compatibility libstdc++
                     library.

                        BIOS flash will proceed but VPD data will be inconsistent.

                     If the above message is shown, install the OSA BMC driver and IBM IPMI
                     mapping layer from the support web page.
