Basic BIOS password crack – works 9.9 times out of ten

This is a password hack but it clears the BIOS such

that the next time you start the PC, the CMOS does not

ask for any password. Now if you are able to bring the

DOS prompt up, then you will be able to change the

BIOS setting to the default. To clear the CMOS do the

following:
Get DOS prompt and type:
DEBUG hit enter
-o 70 2e hit enter
-o 71 ff hit enter
-q hit enter
exit hit enter
Restart the computer. It works on most versions of the

AWARD BIOS.
