BIOS TBL Jumper: JP2
The system cannot boot if the BIOS fails to be flashed in
conventional flash BIOS process. But not to worry when
you use the BIOS TBL function. It is used to protect BIOS
“Top Boot Block”. The system still can boot by using this
function even if the BIOS fails to be flashed. To utilize
this function, you just need to lock pins 2 and 3 together
with the jumper cap.
BIOS Write-Protection Jumper: J2 (optional)
If the jumper J2 set as CLOSED, the system BIOS is
protected from being attacked by a serious virus, such
as the CIH virus. You will be unable to flash the
BIOS to the motherboard when the system BIOS is
protected.
