Dell Optiplex Micro Plus 7020

Motherboard 232014-1 N25VK$HA

Hi everyone,

I'm facing a bit of a situation here and would appreciate some help from the experts.

I received a unit that was BIOS password protected. Unfortunately, during the initial dump, there was a verification error that I didn't catch in time, resulting in a corrupted original file. I tried flashing another BIOS chip with a different dump, but the device is now a "no power/no display" state.

Fortunately, I have an identical unit (same model, same motherboard version/revision) and I have just performed a verified backup of its working BIOS.

I need help with two things on this working dump:

1. Clean ME Region: To ensure compatibility and avoid initialization delays or shutdown issues.
2. Disable BootGuard: If possible, to allow the modified BIOS to run without signature issues.

I have attached the working dump from the twin machine below.

Thanks in advance for any help! And a friendly reminder to everyone: always double-check your verify logs before erasing the chip!
