From article <9005262017.AA02531@jade.berkeley.edu>, by DLV@CUNYVMS1.BITNET:
 
 I have a '386 motherboard with lots of Chips and Technologies stuff on it. At
 boot time, I have the option to run setup/extended setup. While trying to do
 something, I managed to alter the settings in 'extended setup' part (the bits
 in various 'C&T CMOS registers') in such a manner that the machine will no
 longer boot; when I reset it, it goes beep-beep-beep pause beep-beep-beep...
 
 Of course my initial reaction was to try to disconnect the battery and let the
 CMOS memory clear itself; alas, it doesn't seem to be possible on this
 motherboard!!! (Or at least I don't see how). It's got a 10-year rechargeable
 battery that's evidently soldered to the board. Whatever skimpy documentation
 there is does not deal with the question of disconnecting the battery.

Hey guy, nice to hear from other people that I'm not alone in
doing silly things like this...

But I'm afraid there's nothing left do to but to solder out the
damn battery, - or what about waiting for some years or so until
the voltage gets low enough for the CMOS to forget all about your
fiddling with internal regs settings...
