1.7.2 CMOS clear (J1)
The PCA-6005 CPU card contains a jumper that can erase CMOS data
and reset the system BIOS information. Normally this jumper should be
set with pins 1-2 closed. If you want to reset the CMOS data, set J1 to 2-3
closed for just a few seconds, and then move the jumper back to 1-2
closed. This procedure will reset the CMOS to its default setting.

1.7.3 Watchdog timer output (J2)
The PCA-6005 contains a watchdog timer that will reset in case the soft-
ware fails to reset the watchdog timer. The J2 jumper settings control the
outcome of what the computer will do in the event the watchdog timer is
tripped.
