Heh heh, BIOS passwords are a trivial issue if you are the device owner
and can take your time. First, there are large lists published to the
internet of those master codes you are refering to, but more importantly
A BIOS password is stored in volatile memory that is supported by the
CMOS battery (Little watchbattery looking thing the size of a washer.)
Remove the laptop battery, AC-adapter cord and then pen the laptop and
remove the CMOS battery. Attempt to power it on a few times (Hold power
button for 45seconds or so, repeat) This is usually enough to drain the
residule charge from the capacitors and wipe the volatile memory. If that
fails, do it again, and wait 24-48hours before putting any power back to
the device.
