Btw (ByTheWay)  BIOSs are not passworded the way you are suggesting. Simply
removing power from the bios (remove battery or battery connection on MB
(motherboard) will reset any passwords and "Clear" the BIOS back to
defaults - not an expensive or complicated fix. This depends on make and
model of MB. Also some (such as Dell, if memory serves me) have a reset
shunt (aka jumper) and on others you have to remove power by disconnecting
the battery.

On newer systems that may be but I remember the Sun Sparc machines, which did
not  do a password clear even if the removable prom was taken out.  Later I
learned if you leave it out for a couple days (yes days!). It will PROBABLY
reset itself.  I've had one out for three days and it still didn't reset.
