9 PCA-6028 User Manual
Chapter 1 Hardware Configuration
1.8.2 BIOS CMOS (JCMOS1)
The PCA-6028 CPU card contains a jumper that can erase BIOS CMOS/ME data
and reset the system BIOS information. Normally this jumper should be set with pins
1-2 closed. If you want to reset those data, set JCMOS1/JME1 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/ME to its last status or default setting.
1.8.3 Watchdog timer output (JWDT1)
The PCA-6028 contains a watchdog timer that will reset the CPU in the event the
CPU stops processing. This feature means the PCA-6028 will recover from a soft-
ware failure or an EMI problem. The JWDT1 jumper settings control the outcome of
what the computer will do in the event the watchdog timer is tripped.
(JOBS1) is a 2-pin connector for setting enable/disable alarm while the on-board
security event acts.
