Dick move dad.

 

Did you remove the battery while the PC was unplugged from the wall?

You're SOL if you can't remember it really. By design, you can't bypass/reset it without knowing it or replacing the BIOS chip. 

 

You can try removing CMOS battery with the PC unplugged and wait a few minutes, but I wouldn't expect it to clear the password seeing as you've already used the jumper pins. Would be pretty useless if you could bypass the password that easily.

After removing the battery turn on the system without it and see if the BIOS works without it if it does then save the settings then put it back on.

I just found out that many motherboards use a NVRAM chip for storing the BIOS password and Re flashing the BIOS should clear the NVRAM and remove the password:-

Buy a bios programmer like ch341a and you will prob want one with a clip included so you dont have to mess with soldering

 

The chip is usually near the cmos battery

 

Personally i use asprogrammer for my bios flashing needs, but tbh i only flash my bios for overclocking purposes

 

Maybe try flashing to a z77 mpower if you care about overclocking at all
