locked, the BIOS boot block cannot be accessed, making BIOS update impossible.
When BIOS update is intended, remove the jumper cap to disable BIOS flash protection.

System Configure Jumper: CN40

The CN40 jumper determines which mode the system will enter while powered
on. Under Normal Mode, the system will enter the assigned OS as usual. Under
Configure Mode, the system will directly enter BIOS setup utility. This enables you to
modify the BIOS configurations. Under Recovery Mode, you have to insert certain
boot disk into the floppy drive before powering on the system. After powered on, the
system will read the boot disk and enter DOS. This enables you to update the BIOS
with a Flash utility if necessary.
