Nobody but eMachines TS can tell you that for certain. Even if you find someone with a eMachines that has done it, ... Unless they have the same model/Bios ...
If they are using some mainstream industry mobo, then maybe you can read the model # and verify the BIOS revision ... given that info, we can help (with certain authority) ... otherwise, all we can tell you is if it will fit in the socket (which is no guarantee)
Regardless ... your bud should flash his eBIOS w/latest revision.
