Recover from a CMOS memory-affecting virus or work around a boot-time password by making BIOS forget all it once knew.

A BIOS password can be very effective at controlling access to your personal computer.

However, there are sometimes legitimate reasons for bypassing this protection; most often it is because the password has been forgotten or otherwise lost. This downloadable hack from PC Hacks: 100 Industrial-Strength Tips & Tools, by Jim Aspinwall, shows you how to bypass the CMOS settings and the BIOS password to allow the system to boot to a useable state.
