Recovering The Bios With Crashfree Bios - Asus P4S800-MX User Manual

2.1.5 Recovering the BIOS with CrashFree BIOS

The CrashFree BIOS auto recovery tool allows you to restore BIOS from a floppy
disk that contains the BIOS file, in case the current BIOS on the motherboard fails
or gets corrupted.
• To use the CrashFree BIOS feature on this motherboard, install a VGA card
in one of the expansion slots before rebooting the computer. On
motherboards with onboard VGA, such as the P4S800-MX, you will not see
the screen display when the BIOS crashes even if you reboot the computer.
• Prepare the floppy disk that contains the motherboard BIOS
(P4S800MX.ROM) before proceeding with the BIOS update process.
• If you have saved a copy of the original motherboard BIOS to a bootable
floppy disk, you may also use this disk to restore the BIOS. See section
"2.1.1 Creating a bootable floppy disk."
To recover the BIOS from a floppy disk:
1. Boot the system.
2. When a corrupted BIOS is detected, the following message appears.
Bad BIOS checksum. Starting BIOS recovery...
Checking for floppy...
3. Insert a floppy disk that contains the original, or the latest, BIOS file for this
motherboard (P4S800MX.ROM). If the BIOS file that you downloaded from the
ASUS website has a different filename (e.g. P4S800MX_1001.ROM), rename
it to P4S800MX.ROM. The BIOS update process continues when the
P4S800MX.ROM is found.
Bad BIOS checksum. Starting BIOS recovery...
Checking for floppy...
Floppy found!
Reading file "P4S800MX.ROM". Completed.
Start flashing...
DO NOT shutdown or reset the system while updating the BIOS! Doing so may
cause system boot failure!
4. When the BIOS update process is complete, reboot the system.
