Flash the BIOS
Last updated: 4/8/99

  Boot the computer and check the date of the motherboard BIOS which is displayed right at the beginning of the boot sequence.  If it older than the one that you downloaded, the motherboard BIOS should be flashed.  But first, I'll warn you that you will be taking a chance if you do this and you will be doing it at your own risk.

If something goes wrong (e.g., a power outage) during this process you could end-up with an unbootable motherboard.  If that happens you will have to find someone with the equipment to flash the BIOS, obtain another BIOS, or buy a new motherboard.  I've done it many times without a problem.  Someday it's going to get me.

  Ok, let's flash the BIOS.

  • Read the instructions you downloaded:
  • Boot the computer on a DOS floppy
  • Insert the floppy with the Award flash utility and the new BIOS
  • Type "awdflash" (without the quotation marks) at the DOS prompt
  • Type-in the complete file name, including the extension of the new BIOS when asked
  • Press enter
  • See if the check sum matches the check sum you noted when you downloaded the BIOS
  • Type "n" when it asks you if you want to safe the old BIOS
  • Type "y" when it asks you if you are sure you want to program the BIOS.
  • Hold your breath and pray.
  • Push the F1 key when its done to reboot the printer and power-down

  Move the jumper on JP2 (right in front of the battery) on pins 2-3, to the right.  Go get a cup of coffee while the CMOS discharges (I'd give at 10 minutes), come back and move the jumper back to pins 1-2, and power-up.

After flashing the BIOS it is a good idea to clear remnants and settings from old BIOS that may still be in the CMOS memory.  This will cause the BIOS which you programmed into the flash memory chip to reloaded and set the CMOS to its default values for the new BIOS.
