Q: How To Clear CMOSA:
Quick Clear NVRAM
|It may be necessary, on occasion, to clear the CMOS settings. When the CMOS is cleared, all information stored in the CMOS is replaced by default data, which means that all of the configuration information, such as hard drive types and I/O port setup, is cleared, including the password.
Use the following procedure to clear CMOS:
- Power down the computer.
- Remove the left cover of the computer.
- Wearing an anti-static wristband grounded to the chassis, remove the jumper from pins 1 - 2 of the Clear CMOS jumper block (JP15) and install it on pins 2 - 3.
- Remove the jumper from pins 2 - 3 of the Clear CMOS jumper block (JP15) and install it on pins 1 - 2. (NOTE: Some earlier systems will power up as soon as the jumper is removed from pins 1-2. Later versions of the BIOS change this, 6.00.10 or later.)
- Reinstall the cover and power up the computer.
- Run the BIOS Setup program to reconfigure the system.
Note: This clears NVRAM only (all PCI and ISA configuration resources). It does not clear all of CMOS or passwords. To clear all of CMOS and passwords, use jumper JP15.
- Enter CMOS setup by pressing F2 after turning on the system.
- Go to the Advanced menu.
- Select Reset Configuration Data.
- Choose Yes.
- Save and Exit.
- Reboot the system.
- System will reset configuration data for plug and play devices automatically.
