    Hello, I replace the BIOS chip because my client don't remember the EFI password and now with the new BIOS doesn't start the installation. The computer is too low. I put a new installation finished in USB hard disc and start but in a few seconds only appears the Apple logo and don't do anything. I replace with two BIOS and do the same. The apple test appears GOOD. Please help me. Thanks.

    Did you flash the ME on the BIOS? You have to do that because they are locked to the specific PCH.
