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.

is tripped.
