BIOS-Protection Jumper: TBL_EN
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 leave this
jumper as default (pins 2 and 3 together with the
jumper cap).
