As you can see there are various ways on bypassing/changing BIOS passwords.
I have successfully used all of the options below on various computers many years ago.
These methods will work on computers of today. I have updated the Standard BIOS
backdoor passwords for current computers made as of last week. ( big grin ).
READ EVEYTHING BEFORE YOU USE ANY METHOD LISTED BELOW.
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.
Accessing information on the hard disk
When you turn on the host machine, enter the CMOS setup menu (usually you have to
press F2, or DEL, or CTRL+ALT+S during the boot sequence) and go to STANDARD
CMOS SETUP, and set the channel to which you have put the hard disk as TYPE=Auto,
MODE=AUTO, then SAVE & EXIT SETUP. Now you have access to the hard disk.
Standard BIOS backdoor passwords
The first, less invasive, attempt to bypass a BIOS password is to try on of these standard
manufacturer's backdoor passwords:
