1.7.2 CMOS clear (J1)

The PCA-6005-B 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-B contains a watchdog timer that will reset in case the
software 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.
