How do I flash the BIOS?
To upgrade your BIOS, follow the steps below. If you follow them exactly you should experience no problems. Do not skip or modify any step.
In order to flash update the BIOS, you will need a floppy disk containing the the following:
DOS without any memory management drivers installed. I recommend you use the DrDOS 7.X boot disk designed specifically for BIOS flashing (also available on the downloads page).
The BIOS *.bin (or *.b00 or *.b01) file you wish to update to
The previous BIOS *.bin file (just in case you wish to flash back!)
The latest AWDFLASH.EXE utility from ABIT (also available on the downloads page)
The ABITFAE.BAT file from ABIT (also available on the downloads page)
Optional: ABIT have started supplying a file called RUNME.BAT with their BIOS releases which calls ABITFAE with the BIOS filename. You can put this on the floppy disk if you wish, and then instead of Step 6 below, type "RUNME".
Note that ABIT often supply their BIOS files as executables (eg. KT7_WW.EXE). You will need to run this executable (which is a self extracting Zip file) to get the BIOS binary file and possibly also AWDFLASH.EXE, ABITFAE.BAT and the optional RUNME.BAT. You may also encounter BIOS distributions in *.zip files, in which case you must first extract the zip file using WinZip (available on the downloads page).
Shut down your computer properly, then turn it off.
Restart the computer with the DOS diskette in the floppy drive
At the A: prompt, type DIR to check the files on the floppy disk. Assuming all the files in Item 1 of this list are present, go to the next step
At the A: prompt type ABITFAE filename - where filename is the name of the *.bin or *.b00 file you are using. (If you installed RUNME.BAT, you can simply type RUNME instead)
The utility will ask you to confirm a number of things, and will then automatically flash the BIOS with the correct parameters. Once it has finished go to the next step.
Press F1 to reset, then immediately press DEL to go into BIOS, then please:
Go into CPU SoftMenuIII to adjust your CPU speed and voltage (please make sure the CPU voltage matches your CPU specs)
Set up any other BIOS parameters you required (remember you will need to redetect your hard disks!!)
Save and Exit
You're done.
ABIT now have a step-by-step guide with pictures which may help - click here! Note that the steps they describe are slightly different to those above, however.
Remember that if you need to clear your CMOS with the jumper on the motherboard, you will need to reset the computer's clock!
