Usually there's a jumper which you add, power on, off again, and
remove. The problem is finding it. You might be able to find out
the mobo type from http://www.ping.be/bios particularly if there's
a number displayed when you boot, like
(C) American Megatrends Inc.,
40-0101-021291-00101111-060691-OPWBSX-F
(This particular board clearly marks which one with
1-2: CLEAR CMOS 2-3: NORMAL)
Disconnecting the battery will work, though you lose the entire CMOS
setup. But I suppose the defaults ought to work.
