1.0  Updating IBM Netfinity 5500 M20 POST/BIOS
______________________________________________

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

   1. Insert the "IBM Netfinity 5500 M20 POST/BIOS Flash Diskette"
      into drive A.
   2. Start up or restart your IBM Netfinity 5500 M20 server.
   3. The system will boot off of the diskette and present
      a window which allows you the option to flash various
      options.  Choose "1 - Update POST/BIOS".  Then choose
      the number for the language you wish to use during POST and
      in Setup.
   4. After the images are loaded from diskette, 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.
   5. After that selection completes, you will be asked if you would
      like to save the current code to a diskette.  If you select 'Y',
      you need to have a formatted diskette already available.
   6. After this completes 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 return to reboot the system.
