Another alternative: Just remove the battery that keeps the CMOS charged.
I assume that if you're going to install Debian anew, that you won't care about
losing it's settings.
Cheers,

Hello there,
I found a pretty nice 486 PCI-motherboard in the bulk waste last week,
which I would like to use as secondary computer with debian. The board is
working, but unfortunately, it was setup in a way that you can only boot
from harddisk, and shadow RAM was enabled. So I tried to change the
settings, but the preliminary user has installed a Setup-Password, so that
I can't access the BIOS. I know, that there are ways to get around this,
but I don't know how to do it in this special case.
So does anybody know where to find the necessary information? Is there a
tool for Linux or DOS to access and change BIOS-settings (I could plugin
the harddisk from another computer and try to boot into Linux or use the
small DOS-partition I have on this disk). Or is there some kind of cheat
password, which will always work?
The BIOS is a Phoenix version 4.04.
You could write a little program or use dos debug to wipe out the cmos data
at port 0x70 index, 0x71 data. (Containing something like:
for (i=0; i<0x80; i++) {
outp(0x70, i); outp(0x71, 0);
} )
In fact, it's only necessary to alter the checksum, and the bios should reset
to the defaults.
