The BIOS configuration can be reset to factory defaults by either removing the back-up battery or shorting the "CLEAR" jumper on the motherboard.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The BIOS configuration can indeed be reset to factory defaults by either removing the back-up battery or shorting the "CLEAR" jumper on the motherboard. This is a common practice when troubleshooting or when the BIOS settings need to be reverted to their original state. Removing the back-up battery disconnects the power source to the BIOS chip, causing it to lose all saved settings. Shorting the "CLEAR" jumper temporarily connects the two pins, effectively erasing the BIOS settings. Both methods are valid ways to reset the BIOS configuration.Rate this question:
