How to Build Your Own Pentium II  Computer
Flash the BIOS
Last updated: 4/12/99

  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.

  If you haven't downloaded the BIOS and Award Flash utility, do so now.  Make a bootable floppy without any drivers in the autoexec.bat and config.sys files and copy both to the floppy.

I use DOS 6.22 for the floppy.  You could copy these files to your hard disk and boot it according to Abit's instructions.  But, I assuming the hard disk is new and has not been prepared yet.  You could also wait until after you have installed Windows to Flash the BIOS.  But my way is the safest way to avoid possible problems during the Windows installation.  With this motherboard, however, Abit's method is ok.  It may not be with other motherboards.

  Read the instructions on Abit's Web site.

I do it a little bit differently.

  Boot the computer

  Press the Delete when prompted to go into the CMOS Setup

  Select the BIOS FEATURES SETUP and disable the CPU Level 1 and Level 2 Cache,' and Video BIOS Shadow

  Esc to the main Setup Menu

  Select the CHIPSET FEATURES SETUP disable Video  and System BIOS Cachable

  Boot the computer with the bootable DOS floppy with the Award flash utility and the new BIOS

  Type "awdflash newbios /py /cc /sn /cd" (without the quotation marks and where newbios is the file name of the new bios; e.g., bh6_kg.bin) at the DOS prompt and press enter.

Hold your breath and pray.

Push the F1 key when it's done to reboot the printer and power-down

  Move the jumper next to the left ISA expansion board slot to pins 2-3, the two towards the front of the motherboard.  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.
