Someone, please help. I need these bios. Here is the serial no of one CPU, don't know which one because I only recieved motherboards. If possible, provide me just one bios with clean ME. Thanks.

I tried RCUnlocker and HPUnlocker. RCUnlocker doesn't support this file while HPUnlocker created a new file but didn't remove/ unlock the password.

krhms519, I didn't remove the password, hoaca388 removed the password for me. Post the backup of your bios in this thread and one of the experienced members will do it for you.

Hi hoaca388,

I want to understand what you did to unlock the BIOS password. It is mostly for personal learning on this.
I downloaded both the original password reset file, and your unlocked one, and open them both in a hex editor to compare and see the differences.

I saw you replaced some elements with FF to reset stuff. Your are requesting the Serial numbers though, so where is this info going in the bios ? Is there actually any S/N in the BIOS, or is it really just reseting some actions in the BIOS ?

Thanks for the explanation, I am very curious

PS : Sorry for taking out this thread, but since it's the same machine, I thought it was ok to do so.

I ask for the serial number because it is a forum rule.
