Clearly something in CMOS got wonky (technical term for "corrupted" :-) There's a capacitor in the circuit that keeps the CMOS powered for a short time (minutes) so you don't lose the clock and custom settings when you replace the battery. The jumper shorts the capacitor and battery across a resistor to completely remove power from the CMOS and force it back to factory defaults. > Another new experience where I could not use prior knowledge to fix the > problem. -- Jim Garrison [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
