On the IBM Thinkpad T42, there are two separate passwords that can function like a normal BIOS password. Typically, a BIOS password must be entered at start-up in order to enter the BIOS set-up utility or to load the operating system. On the Thinkpad T42 a POP (power on password) can be established that must be entered at start-up to begin the booting process. Beyond that, an optional SVP, or supervisor password, can be set to protect the BIOS set-up utility exclusively. According to IBM, if you lose the SVP you'll need to replace the motherboard. The POP can be reset though.
