Resetting Bios Password

I am doing some spring cleaning, getting rid of old desktops, laptops, and routers. Regarding the computers, I am wanting to wipe the hard drives with Darik's Boot and Nuke software. When I booted up one old Dell desktop from 2001, I learned that it requires a BIOS password. Why I ever put one on is beyond me. Unfortunately, I have forgotten the password. The rest of this message will be about wanting to know if my understanding for resetting the BIOS password is correct.

Technically, this thread/message isn't about Windows 10 specifically. But it does relate to hardware, and I am hoping that it would apply to a significant number of computers, so I hope this message is okay.

I called Dell, and the technician said that I needed to reset the jumper on motherboard to reset the BIOS password. After opening the case on my old Dell computer and hunting on the internet, this is the what I think I have learned. I will present photograph of a portion of the motherboard.





I have put a red rectangular box around what I think is the jumper for the BIOS. I note that "PASS" is written on the motherboard beside those three pins.

I believe these are steps I need to follow. Please correct me if I am wrong.

1. Turn off and unplug the computer. (It has been off and unplugged for about ten plus years. I just plugged it in today. I am not sure if this information is relevant. Perhaps it helps with regard to the motherboard's battery.)
2. Open the case and locate those "PASS" pins again.
3. Switch the jumper from the current two pins to include the third pin and middle pin. Leave it there for 5 seconds or more. In other words, move the jumper over one pin for a few seconds.
4. Reset the jumper back to its original position with the original pins.
5. Plug in the computer, and attempt to boot it up.
6. Assuming it boots up, open CD tray and put in Darik's Boot and Nuke software and follow the steps.

Is there any information that I am missing? Do I have the correct location for the jumper? Are my steps correct?

Thank you for your help.

 

Pin not working after BIOS Update

Hi Max,

It seems that your operating system was no longer aligned with your BIOS after installing a BIOS update for your HD3P main board.

For us to diagnose and address the problem, we suggest starting your computer in safe mode and check if the PIN is working while in that state. If it's working, then a 3rd party application may have caused the issue. To start your PC in safe mode, please
see
Start your PC in safe mode in Windows 10.

If the PIN is not working in safe mode, then a reset is suggested to correct the problem. The operating system should always go with the BIOS. If the BIOS is freshly updated, then the OS has to be fresh as well. Check out
Reset your PC in the link,
Recovery options in Windows 10 for the steps.

Let us know how it goes so we can further assist you.

Regards.
