How to Build a Computer
AMD Socket A Athlon or Duron Processor
Part 7 - Flash the BIOS and Setup the CMOS
Last updated: 5/28/2001
Flash the BIOS. This step requires
a computer which is interfaced to the Internet, to download the latest motherboard
BIOS from the manufacturer. It can be delayed until after you have
installed Windows and the MODEM (or network adapter for broadband network
access) is installed and configured, but is best done at this point.
First, I'll warn you that you will be taking a chance
if you flash the motherboard BIOS 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.
91. Boot the computer and record the date/version
of the motherboard BIOS, which is displayed right at the beginning of the
boot sequence. You may be able to freeze the screen by pressing the
Pause key. Pressing any other key (e.g, the Space bar) will unfreeze
92. Determine the motherboard manufacturer's web
site Internet address from the documentation that came with the motherboard
or with a search engine.
93. Connect to the web site and find the BIOS downloads
for your motherboard. Look in support, technical support, downloads...
94. If it is newer than the one that you have, the
motherboard BIOS should be flashed. Download the BIOS
and Award Flash utility from the web site, The file I downloaded was
kt7yh.exe. It was "hidden" on Abit's
FTP site and is newer than the one listed on Abit's U.S. and Taiwan
web sites. It is a compressed, self-extracting file. Use the
Windows Explorer and double-click the compressed file to extract the following
||Batch file which automates the flash
||Award flash program
||The new BIOS
||Release notes and instructions
||Batch file which calls ABIFAE.BAT
with the correct parameters for this particular BIOS
Other manufactures may have the files compressed,
but they may not be self-extracting and you may need a program to extract
(decompress) them. I use PowerArchiver to
extract zipped, etc. files. It is totally free and without advertising. WinZip is
another popular program that works quite well.
95. Read the release notes and instructions.
96. Make a bootable floppy without autoexec.bat and
I use a Windows
98 Startup floppy made according to the Manual method. You
could use a Windows
Me boot floppy. A MS-DOS 6.22 bootable floppy works
97. Copy the above files (or the appropriate files
for your motherboard) to the floppy.
98. Boot the computer with the floppy.
99. Ok, let's flash the BIOS. Abit makes it
simple. Just type runme at the prompt:
But, let's assume, for demonstration purposes, that Abit
did not make it simple (many motherboard manufacturer's do not provide the
batch files). Typing the following at the DOS prompt will also flash the
A:\>awdflash KT7_YH.BIN /cc /cd /cp /py /sn /cks /R
To learn more about the awdflash program, type:
Or, you can do the whole thing manually, by typing...
And enter the BIOS file name to program when prompted (in
this case KT7_YH.BIN with the .BIN).
Indicate whether or not you want to save a copy of the
old BIOS and, if you decide to save a copy, where to save it, when prompted.
I usually do not save the old BIOS.
Type "Y" when it asks if you if
you are sure your want to program the BIOS and hope there is no
Push the F1 key when it's done to reboot the computer and
power-down and unplug the computer.
100. Move the jumper (CCMOS1) to left, rear of the
CMOS battery to pins 2-3, the two towards the back 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. Do
not apply power to the motherboard with the jumper on pins 2 and 3. It
can damage the motherboard.
