Configuration Jumpers
A 10-pin block, located between the secondary IDE connector and DIMM 2B, provides four 2-pin jumper
blocks that are used for system recovery and update options. During normal operation, jumpers are
stored on four pins: pins 7 and 8, and pins 9 and 10. The figure below shows the jumper pins. Their
functions are listed in the table below the figure.

Jumper Name Pins What happens at system reset…
Password Clear
1-2 If these pins are jumpered, administrator and user passwords will be
cleared on the next reset. These pins should not be jumpered for normal
operation.
BIOS Recovery
3-4 If these pins are jumpered, the system will attempt to recover the BIOS
by loading the BIOS code into the flash device from a floppy disk. This
jumper is typically used when the BIOS has become corrupted. These
pins should not be jumpered for normal operation.
CMOS clear 5-6 If these pins are jumpered, the CMOS settings will be cleared on the next
reset. These pins should not be jumpered for normal operation.
BIOS Booblock
Write Protect
7-8 These pins, when jumpered, protect the BIOS Boot Block code. If it be-
comes necessary to update the BIOS Boot Block, this jumper should be
removed during the update process. These pins should be jumpered for
normal operation.
NOTE: This jumper should remain in place for normal BIOS operational
code updates.
Default 9-10 These pins are for normal operation.
 NOTE
The jumper should remain on pins 7 and 8 at all times until you are instructed to perform a BIOS Boot
Block update. At this time, remove the jumper, run the BIOS update, and then replace the jumper
when completed.
