BIOS-Protection Jumper (JAV)
The BIOS of the mainboard is inside the FWH. If the jumper JAV 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.
However in this status .
Setting the jumper JAV as open(default), allows you to flash the BIOS to the
Flash ROM.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 JAV as closed makes flashing BIOS
and updating DMI information impossible. Therefore, set JAV as open when
changing the system hardware configuration, or the error message “Unknown
Flash Type” will be displayed on the screen, and DMI information may not be
updated. Under special conditions, the jumper “JAV” should be set as OPEN.
