HOW TO REMOVE BIOS PASSWORD
If you have put a password to your BIOS in the computer store and you do not know it, or if your work computer has a BIOS with a password, you can use this manual to delete the password.
With this manual what is achieved is simply to restore the default values of the BIOS and therefore also the BIOS password.
VERY IMPORTANT: when loading the default BIOS values, if your computer had some special configuration, it does not work correctly. While it is true in most cases there is no problem and it is not usual to have any option changed if it was not for the same user. Older computers need to detect hard drives in the bios IDE AUTODETECTING DEVICES menu.
Try to access the BIOS and see what model it is. Since you do not know the password (password), go back to restart and enter into windows. It can be AMI / AWARD, PHOENIX or other more RARE models.
Access the command line: start> run> type cmd or command (depends winNT or win9x).
Write debug, enter the debugger. write the following respecting the spaces, depending on the model of the BIOS:
BIOS AMI / AWARD
or 70 17
or 71 17
PHOENIX BIOS
o 70 ff
0 71 17
Other BIOS
o 70 2e
o 71 ff
or => this is a low O vowel.
To exit the debugger, just type q and hit enter.
Restart the PC. The BIOS has been reset to default values, and therefore, it has no passwd!
It has nothing to do with the OS just with the BIOS mark.
Serves for all versions of windows.
in case you want to remove the password of the bios without jumpear or remove the battery
This simple trick can avoid that we have to use the screwdriver to reset the BIOS, as long as the password is not a boot, but access to the BIOS.
It is necessary to perform the following steps:
In the start menu press run.
type debug
Once inside the debug type the following:
or 70 17
o 71 ff
q
The password is already reset!
