Open a new browser window. Go to cgsecurity.org.

Step 2. Select CmosPwd from the left side of the Wiki. Download the zip file.

Step 3. Unzip the contents into a separate folder.

Step 4. Navigate to the Windows subfolder.
Select Shift, then Right-click inside the folder. Select "Open command window here". A DOS box opens up.

Step 5: Type " ioperm -- I" to install the Cmos reading service.

Step 6: Type cmospwd_win.exe /k if you want to erase your old BIOS password. The executable offers you following options:
1 - to erase Cmos,
2 - to erase Cmos, but try to preserve date and time,
0 - to cancel. If you absolutely don't know your password, select 1 or 2, otherwise select 0.

Step 7: If you have any of the popular BIOSes listed in the cgsecurity.org/wiki/cmospwd page, you might try running just
cmospwd_win.exe
at the DOS box command prompt.
The utility will dump the most common places of your BIOS looking for your password.

Result: Depending on your case, you have successfully recovered or reset your BIOS password.
