        3.0   Installation and Setup Instructions

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

              3.1  Insert the "IBM xSeries 336 POST/BIOS Flash Disk"
                   into drive A.

              3.2  Start up or restart your IBM xSeries 336 server.

              3.3  The system will boot from the disk and present a
                   menu which allows you to choose from various update
                   options.  Choose "1 - Update POST/BIOS".

              3.4  You will be asked if you would like to move the current
                   POST/BIOS image to the backup ROM location.  If you
                   select 'Y', the current code will be flashed in to the
                   backup bank immediately.

              3.5  If the current system POST/BIOS supports the Asset Tag
                   feature, you will be asked if you would like to change it.
                   If you select 'Y', you will be able to enter a new number.

              3.6  You will then be asked if you would like to save the current
                   code to a disk.  If you select 'Y', you need to have
                   a formatted disk already available, or specify a fully
                   qualified path and file name.

              3.7  You will then have a final opportunity to proceed with the
                   Flash update or exit the utility.  If you proceed, the
                   utility will update the Flash ROM with the new code.  When 
                   this is complete you will be prompted to remove the diskette
                   and press Enter to reboot the system.
