SuperBIOS-Protect
The BIOS of the motherboard is contained inside the Flash ROM. Severe viruses,
such as the CIH virus, are so dangerous that they may overwrite the BIOS. If the
BIOS has been damaged, the system will be unable to boot. We provide the
following solution which protects the system BIOS from being attacked by such
viruses.
There are two ways to implement this function:
1. Set the jumper (FWH_EN) to disable; the flash ROM cannot be overwritten.
2. Set the jumper (FWH_EN) to enable and enable “SuperBIOS-Protect” in the
CMOS section of BIOS Features. In this way, the BIOS cannot be overwritten,
but the DMI information can be updated.
Note: FWH_EN default is enable.
