Re: [vox-tech] Best way to clear a BIOS password

Speaking of Mark's jumper suggestion (and maybe he's talking about the
same thing), won't reading the mo-bo docs and finding the _bios reset_
jumper do the trick?  Usually it's a three pin jumper, even on
_jumper-less_ motherboards, and you turn the power off AND upplug the
power.  Then you put the jumper on the other two pins for a few seconds,
the put it back, and turn the power on.  I've done this to fix a lot of
things, but I've never used a bios password, so for all I know, the bios
password is smarter than that...
