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.
