BIOS TBL Enable Jumper: JP1
The system cannot boot, if the BIOS failed to be
flashed in conventional flash BIOS process. You
will have no such worry when using the BIOS TBL
function, which is used to protect BIOS “Top Boot
Block”. By using this function, the system still can
boot even if the flash BIOS fails and show some
information to recover the BIOS. To utilize this
function, you just leave this jumper as “enabled”
(short pin 2 and 3 with the jumper cap).
