A BIOS password protects a machine by locking the initial boot process. On an ASUS EEE PC, you can tell that a BIOS password is set because your computer's Caps, Num, and Scroll Lock buttons will flash. Depending on the make and model of your machine, there are a number of ways to reset the BIOS password. While the standard technique would be to access the motherboard itself and remove the CMOS battery, this may not be an option for those unwilling to fully disassemble their EEE PC.
