1.8.4 CMOS clear (J1)

The PCA-6178 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.

1.8.5 Watchdog timer output (J2)

The PCA-6178 contains a watchdog timer that will reset the CPU or

send a signal to IRQ11 in the event the CPU stops processing. This

feature means the PCA-6178 will recover from a software failure or an

EMI problem. The J2 jumper settings control the outcome of what the

computer will do in the event the watchdog timer is tripped.
