In a legacy BIOS, what two types of system password can be configured?

A password to start the PC (user) and a password to access system setup settings (supervisor).

If you want to enforce TPM system security, what other BIOS feature should you enable?

A supervisor password to prevent the TPM keys being accessed or cleared.

Name three keys commonly used to run a PC's BIOS/UEFI system setup program.

Esc, Del, F1, F2, F10.

Where should you launch a typical firmware upgrade utility - from system setup or from Windows?

If the option is available, it is safer to run a firmware upgrade from the system setup program as it reduces the risk of some other process interfering with the update.

A user's computer was recently installed with a new optical drive. The user now reports a "chassis" error message after the POST sequence. What might be the cause?

What security system allows system boot to be disabled if the computer is reported stolen?

LoJack.

True or false? Processor extensions such as VT and XD are set by the vendor depending on the CPU model and cannot be enabled or disabled by the user.

Mostly false. A feature such as VT is sometimes disabled on some low-end models but if it is available as a feature of that model the user can choose whether it is enabled or disabled.

What widely-supported boot method is missing from the following list? HDD, FDD, Optical, USB.

Network / PXE (Pre-eXecution Environment) - obtaining boot information from a specially configured server over the network.

What advantages does UEFI have over BIOS?

UEFI supports 64-bit CPU operation and better hardware support at boot. This allows for full GUI system utilities and mouse support plus better system startup security options (such as pre-OS boot authentication).

If Windows will not boot, is it possible that a system diagnostics check could still be run?

Yes - a diagnostics tool could be installed to a separate partition and loaded by pressing a key at startup.
