NOTE:
The PM-LX2-800 does not provide a “Clear CMOS” configuration jumper. If the
system fails to boot due to improper BIOS settings, reset the CMOS contents by
disconnecting and reconnecting the BT1 battery connector. Use small-sized needle
nose pliers to carefully disconnect and reconnect the BT1 battery connector.
