Description
If pins 2 and 3 are jumpered (default), the BIOS boot block is write-protected. If pins 1
and 2 are jumpered, the boot block is erasable and programmable. WARNING:
Incorrect programming of the boot block will render the system unbootable. With
this option set to its default factory setting, the BMC's operational code can still be
programmed without moving the jumper.
If pins 4 and 5 are jumpered (default), preservation of configuration CMOS through
system reset is controlled by the BMC. If pins 5 and 6 are jumpered, CMOS contents
are set to the manufacturing default during system reset.
If pins 7 and 8 are jumpered (default), the current system password is maintained
during system reset. If pins 8 and 9 are jumpered, the password is cleared on reset.
If pins 10 and 11 are jumpered (default) the system will attempt to boot using the BIOS
programmed in the Flash memory. If pins 11 and 12 are jumpered, the BIOS will
attempt a recovery boot, loading BIOS code from a CD-ROM disk into the Flash device.
This feature is typically used when the BIOS code has been corrupted.
