2.1.5 Recovering the BIOS with CrashFree BIOS 2
The CrashFree BIOS 2 is an auto-recovery tool that allows you to restore BIOS
from the motherboard support CD, or from a floppy disk in case the current BIOS
file fails or gets corrupted.
• Prepare the support CD that came with the motherboard or a floppy disk
that contains the motherboard BIOS (P4R800VM.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 (P4R800VM.ROM). If the BIOS file that you downloaded from the
ASUS website has a different filename (e.g. P4R800VM11.ROM), rename it to
P4R800VM.ROM. The BIOS update process continues when the
P4R800VM.ROM is found.
Bad BIOS checksum. Starting BIOS recovery...
Checking for floppy...
Floppy found!
Reading file “p4r800vm.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.
