Solution to broken intel iMacs

On: EFI Modifications Leaves iMac Unbootable?

It seems that Dave Schroeder has posted the following instructions over at Nakfull Propaganda to fix those broken intel iMacs;

By following these steps, the iMacs that had difficulty with certain EFI modules appear to have been restored to a functioning state:

1. Disconnect the internal hard disk

2. Disconnect the iMac from AC power

3. Plug in AC while holding the power button

4. Power up the iMac and zap NVRAM (cmd-opt-P-R)

The hard disk can be reformatted and the operating system restored.
