[OFFTOPIC] BIOS Password defeat

[Daniel Reuter <reuter@Uni-Hohenheim.DE>]

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.

Regards,
Daniel
