BIOS-Protection Jumper (BIOS_WP)
The BIOS of the mainboard is inside the FWH. If the jumper BIOS_WP is set as
closed, the system BIOS is protected from being attacked by serious virus such as
CIH virus, you will be unable to flash the BIOS to the mainboard in this status.
The DMI (Desktop Management Interface) system information such as the CPU type/
speed, memory size, and expansion cards will be detected by the onboard BIOS and
stored in the flash ROM. Whenever the system hardware configuration is changed, DMI
information will be updated automatically. However, setting jumper BIOS_WP as closed
makes flashing BIOS and updating DMI information impossible. Therefore, set BIOS_WP
as open when changing the system hardware configuration, or the error message " Un-
known Flash Type" will be displayed on the screen, and DMI information may not be
updated.
