This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.

A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:

BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

There should be a jumper on the motherboard that you can change to the reset BIOS mode and then power it up and it will flash the BIOS back to the original state. Some BIOS should also have a option in the actual BIOS settings.

Pheonix BIOS has to be the highest chosen BIOS for most computer manufacturers. In the event of an extreme virus or major malfunction to the motherboard, a simple low cost resolution is purchasing a new one. The ability to "Flash" the motherboard is a task even the most qualified expert cannot guarantee. The manufacturer themselves has went outside their efforts and purchsed the software from the particular BIOS carrier. The file has to be saved on the CPU in a manner that is compliant with your version of BIOS. Meaning the file to revert your BIOS to its original state has to be saved in a manner that version of your BIOS understands. Then an updated BIOS is added to the things to do list because the old version is probably outdated and you will attract the same virus or worse again. Good news is that newer motherboards have updated this whole process and even getting the reset or upgrade function has been added to the bios. Ask the retailer you may purchase a new one for to show you on a display model if possible. Contact me through the bio page for even further details.
