If you have lost access to your system not all it lost.For AMI BIOS go to,"Your"mother board"maker's site or get the BIOS .rom off the CD supplied with the motherboard and you can make an emergency re-flash disk by copying a known good BIOS rom file to it and renaming it to amiboot.rom

This Information can be used with any Award BIOS Update however This is taken from a regular usenet Contributor,"Jef Norton".
Many thanks.
This document specifically addresses Abit's 4A BIOS and later for the KT7/KT7A with additions by myself(P.D.Sheppard).The newer 64 BIOS is now on Paul Howlands Site

If you're flashing to another version or another board, simply change where noted and this post should apply to you in it's entirety but more information here,WimBIOS Page on this and other BIOS.
Here is a Full list of my BIOS Settings after flashing up.

When you ran the self-extracting .exe file or you expand a zip file containing the BIOS, you should have gotten five files onto a holding folder on your hard drive.
readme.txt
adwflash.exe
kt7_4a.bin
abitfae.bat
runme.bat.

Copy them all (readme.txt is optional) to your boot diskette but make sure they are NOT in a folder on the floppy disk!This should be a clean (recommend FULL format and FULL surfaced Scan) DOS or Windows 98 boot diskette with no Config.sys or Autoexec.bat file present.The best way I've found to do this is to use a DrDos(Caldera Dos) boot floppy rather than a Win9X boot floppy to be safe.

You boot with this diskette and type "Runme" - which in turn calls abitfae.bat, which in turn runs awdflash.exe, flashing your BIOS with the kt7_4a.bin file. You'll get several chances to chicken out before the flash actually runs (you're prompted to press Enter to continue three times, if I recall correctly).

Once awdflash.exe starts Don't touch your keyboard until you get the message to press F1 to reset or F10 to exit (at which time you press F1, and when it reboots, immediately press DEL and reenter all your BIOS settings and remove the diskette).You can also switch off at the wall and clear the CMOS if you have problems after this procedure and rest your BIOS settings.

Emergency Re Flash Bootdisk

In preparation for the flash, it's a good idea to prepare a second boot diskette using Drdos again to make it with the original BIOS on it, just in case you wish to go back or your flash fails. Again, full format/scandisk would be a good idea to be certain the diskette is good. This diskette should be set up to auto-run - if your flash failed you are unable to see anything unless you have an ISA video card - this is when the boot block BIOS takes over, providing you a means to boot with another diskette and run the flash again.

Better safe than sorry: before flashing, run a full Format and Full Scandisk on both diskettes.

On this second diskette, you have no config.sys. You have an autoexec.bat which contains the single line
awdflash.exe kt7_##.bin /cc /cd /cp /r /py
(name of flash program) (name of binfile - this should be your current BIOS) (commands)

To flash run the auto-run diskette, place the floppy in drive A:, power up your system, after several minutes your system should reboot itself. When it does, press DEL to get into the BIOS setup screens, reenter everything and remove the floppy.
commands used are:
/CC = clear cmos data after programming
/CD = clear dmi data after programming
/CP = clear pnp (escd) data after programming
/R = reset system after programming
/PY = program flash memory

(The abitfae.bat file, called by runme.bat doesn't contain the /R switch so you have to press F1 when the flash is complete to reset your system).

*****************************************************************
other awdflash commands:
/? = show help menu
/SY = backup original bios to disk
/SB = skip bootblock programming
/TINY = occupy lesser memory
/E = return to dos when programming is done
/F = use flash routines in original bios for flash programming
/LD = destroy cmos checksum and no system halt for first reboot after programming
/CKSxxxx = compare binfile checksum with xxxx
/CKS = show update binfile checksum
/PN = no flash programming
/SN = no original bios backup
/SD = save dmi data to file

Many folks will recommend that you turn of the main power switch at the power supply and move the CCMOS1 jumper to pins 2 and 3 for fifteen seconds, move the jumper back to pins 1 and 2 and turn your main power switch back on after flashing your BIOS - this clears your CMOS to factory defaults. Unless the readme file accompanying the BIOS mentions otherwise, I don't usually bother with this step because the /CD /CP /CC switches are intended to clear the CMOS data on a successful flash. If your flash fails and you need to flash from the boot block BIOS, this may be a good idea (I did it the one and only time I had a flash fail and had to recover from the boot block - my recovery was successful).

Before flashing the BIOS, I have never disabled the CPU Level 1 Cache or Level 2 Cache (in fact, I've never disabled these settings because I believe this would severely handicap your system).

I !!!NEVER!!! enable System BIOS Cacheable or Video BIOS Cacheable in my system as these options enabled will ruin the BIOS chip when flashing!!!!. Special consideration for the Abit KT7_3R/KT7_4A BIOS: When you first boot Windows after flashing the 3R BIOS (or 4A, if you're current version is before 3R) many of your system devices will be re detected. This is primarily due to architectural changes to the BIOS in regard to it's ACPI implementation and should not be cause for alarm. After the initial boot, it would be a good idea to boot into Safe Mode then go into Device Manager and remove all devices which have "ghosts" (multiple occurrences) and then reboot again. More information regarding this can be obtained on Shep's web site Safemode Drivers. Good luck! My caveat: flashing your BIOS may lead to a system that is unusable until you get a new BIOS chip. You may consider installing a Hardware BIOS Savior to minimize the risk.

This is the European Site that also ships to the UK Flask Bios Org and this is the main US source BIOS Saviour USA.

Should you need a new BIOS chip or wish not to flash the BIOS yourself local computer shops will usually do it for a small fee and in the USA Bad Flash will supply a new Chip.
