Review Questions:
1. How do you read into the information configured in BIOS from within Windows?
A. Device Manager
B. Control Panel -> BIOS config
C. MS Config
D. None of the above
2. True or False: It is not necessary to remove the power cord from the PC to install
an Expansion Card, as long as the computer has been shut down.
A. True
B. False
3. True or False: Firmware contains code to fix errors or support new hardware.
A. True
B. False
4. Firmware upgrades include:
A. Security patches
B. Performance updates
C. Known issue updates
D. All of the above
5. True or False: Hard drives and optical drives can be configured through the
system BIOS.
A. True
B. False
Answer Key:
1. D
You cannot view all the BIOS configuration items natively in Windows. You
either have to install a 3rd party application, or boot to the BIOS screen.
2. B
False. The power cord must be disconnected, and best practice is to press and
hold the power button after its removal to drain all resident power.
3. A
True. Firmware contains code to fix errors or support new hardware.
4. D
Firmware upgrades include all of the above.
5. A
True. Hard drives and optical drives can be configured through the system BIOS.
