David configured a password to restrict access to the CMOS setup. Which of the following should he do to remove this password and access the CMOS setup?
  1. Clear the CMOS by shortening the CMOS jumper.
  2. Boot to a floppy and fdisk the drive.
  3. Go into BIOS setup and delete the password.
  4. Boot down the computer while holding down the <CTRL> key.
Explanation
Answer: A - To reset or bypass the CMOS password, clear the CMOS jumper on the motherboard. This clears all the CMOS settings, including the CMOS password.

Key Takeaway: The CMOS password is used to protect any unauthorized changes to the machine’s basic configuration. If you forget the password, you will not be able to enter the CMOS setup. To clear this password and enter the setup, do the following:

1. Locate the CMOS jumper on the motherboard.
2. Remove this jumper from its default location.
3. Refer to the manual for the password reset location. Ideally pin #1 and #2 are default, and pin #2 and #3 are used for a password reset.
4. Keep the jumper in the reset location for 20-30 seconds and then place it in the default location.
