He may of put in a temp graphics card.....or used a dos boot disk with a batch file to create and run the following debug to reset the bios to default.

He wouldn't need to see any thing but just type in what starts the batch file when he felt the computer
was booted up.

Then again, just removing the battery will reset the bios.....
