       1.0   Overview

              1.1  This README file contains the latest information about installing
                   the IBM xSeries x225/Intellistation Z Pro (6221) POST/BIOS code.

              1.2  Limitations - NA

              1.3  Enhancements
              
                   This BIOS flash image update contains an Intel errata patch for
                   the microprocessor firmware. It addresses a potential issue which
                   might cause a system to exhibit erratic behavior such as a system
                   hang, reboot, blue screen or Kernel Panic (Linux), and may also
                   cause in-progress system operations (e.g., file, I/O) to fail.
                   The possibility of this behavior is believed to be limited, but
                   IBM strongly recommends that customers install this update as
                   soon as possible to prevent the possibility of the issues listed
                   above. See Retain Tip H181994 for more details on this issue.

              1.4  Level of Recommendations and Prerequisites for the Update:

              1.5  Dependencies
              
                   For customers using the Integrated Mirroring feature on the
                   integrated SCSI controller, the RAID configuration will be
                   converted to a new format when upgrading to this level of system
                   BIOS. This new format is unreadable by earlier levels of code.
                   If it is necessary to return the system to the previous system
                   BIOS level, the Integrated Mirroring settings will need to be
                   reconfigured.  Documentation of this workaround is available at:
                   http://www.ibm.com/support  


        2.0   Installation and Setup Instructions

              The procedure to update the POST/BIOS is as follows:

              2.1  Insert the "IBM xSeries x225/Intellistation Z Pro POST/BIOS
                   Flash Diskette" into drive A.

              2.2  Start up or restart your IBM system.

              2.3  The system will boot off of the diskette.

              2.4  You will then be asked if you would like to save the current
                   code to a diskette.  If you select 'Y', you need to name
                   the file to be saved. The file will be saved on the diskette.
                   If you select 'N', the utility will continue to the next step.

              2.5  At this point, you will be asked if you would like to continue the
                   POST/BIOS flash update. If you select 'Y', the system will update
                   the flash ROM with the new code.  When this is complete you will be
                   prompted to remove the diskette and hit 'F1' to reboot the system.
	
	      2.6  On the first system boot, after updating the BIOS, select the Setup Utility 
		   with the F1 key; then, select the "Load Default Settings" option.
		   Select the "Save Settings" option, and hit 'y' to save.  Then, select
                   "Exit Setup" to exit the utility, and, finally, accept the displayed
                   'Y' option under "Save and exit the setup utility?"  

      
       3.0  Unattended Mode

             3.1   Steps for unattended mode.

                    3.1.1  Modify AUTOEXEC.BAT on the Flash Diskette to read:
                          "AF.EXE flashfil.fls /py /sn", where 
                          'flashfil.fls' is the file you wish to flash
                    3.1.2  Reboot the system with the Flash Diskette in Drive A:
