        2.0   Change History

               V1.00 - March 1, 2005 (Build ID ZUJT21A)
              --------------------------
              - Initial release
                                            
               V1.01 - March 7, 2005 (Build ID ZUJT23A)
              --------------------------
              - Fix required to prevent system hang during Broadcom PXE ROM execution
                when Serial Over Lan session is active with the BMC.
              - Fix required to prevent intermittent "1602 System Management Adapter Communication" 
                error when the RSA II adatper is installed and AC power has been applied.  
              - Fix required to allow the RSA II "Vital Product Data" section of the web interface
                to properly show the system serial number and machine type.
              - Fix to prevent POST/BIOS from intermittently reporting and disabling memory DIMMs during memory 
                configuration during repeated warm boot or AC cycles.

               V1.02 - March 31, 2005 (Build ID ZUJT26A)
              --------------------------
              - Changed default setting for "RSA II Disable Periodic SMI Generation" to Enabled
                to prevent from RSA II from generating a 15 minute SMI. This periodic SMI is
                not currently used on the x366/x460 and should be defaulted to disabled.
              - Fix to prevent system from generating a NMI if a PCIX Correctable Threshold 
                has been reached. The system will now properly generate a PFA alert if this condition
                occurs.
              - Fix to allow the Automatic BIOS Recovery feature to properly recover from a 
                catastrophic POST/BIOS flash update failure.
	      - Fix to modify the POST/BIOS USB CHS translation to be compatible with that used
                by most laptops. This will require specific USB keys which were bootable before on the x366/x460
		to be re-created.
              - Change to increase performance when running Windows Server 2003 and using the 
                performance monitor application. This fix will also resolve a timer skew issue when running SAP.
              - Fix to properly send the BMC the correct system time during POST/BIOS operation between the
                hours of 19:00:00 and 00:00:00.
              - Fix to prevent a possible system hang when booting from a locally attached USB floppy device.              

               V1.03 - May 13, 2005 (Build ID ZUJT30A)
              --------------------------
              - Initial support for the IBM xSeries x460.
