Question: How do I update my BIOS?
Answer: It is recommended that you do not upgrade your BIOS if you are
experiencing no problems with your system. Updated BIOS files are located
on our web site at http://www.supermicro.com.
Please check our BIOS
warning message and the info on how to update your BIOS on our web
site. Also, check the current BIOS revision and make sure it is newer than
your BIOS before downloading. Select your motherboard model and down-
load the BIOS file to your computer. Unzip the BIOS update file and you will
find the readme.txt (flash instructions), the fwhflash.com (BIOS flash utility)
and the BIOS image (xxxxxx.rom) files. Copy these files onto a bootable
floppy and reboot your system. It is not necessary to set BIOS boot block
protection jumpers on the motherboard. At the DOS prompt, enter the com-
mand "fwhflash." This will start the flash utility and give you an opportunity
to save your current BIOS image. Flash the boot block and enter the name
of the update BIOS image file.
N o te :
It is important to save your current BIOS and rename it
"super.rom" in case you need to recover from a failed BIOS update.
Select flash boot block, then enter the update BIOS image. Select "Y" to
start the BIOS flash procedure and do not disturb your system until the
flash utility displays that the procedure is complete.
After updating your
BIOS, please clear the CMOS then load Optimal Values in the BIOS.
Question:
After flashing the BIOS my system does not have video.
How can I correct this?
Answer: If the system does not have video after flashing your new BIOS, it
indicates that the flashing procedure failed. To remedy this, first clear CMOS per
the instructions in this manual and retry the BIOS flashing procedure. If you still
do not have video, please use the following BIOS Recovery Procedure. First,
make sure the JPWAKE jumper is disabled. Then, turn your system off and
place the floppy disk with the saved BIOS image file (see above FAQ) in drive A.
Press and hold <CTRL> and <Home> at the same time, then turn on the power
with these keys pressed until your floppy drive starts reading. Your screen will
remain blank until the BIOS program is done.
If the system reboots cor-
rectly, then the recovery was successful.
The BIOS Recovery Proce-
dure will not update the boot block in your BIOS.
