EFI Modifications Leaves iMac Unbootable?

jerbare writes "In attempting to run Linux and Windows on the new iMac Core Duo, people experimenting with configuring the EFI Console/Boot loader have found they can no longer boot the machine at all. Dave Schroeder of appleintelfaq.com comments, 'We have already irreversibly lost a couple of iMacs trying to load various EFI modules'. Instructions for breaking the iMac's are presently located at the bottom of the comments."

      Could be worse. If they had succeeded, they'd have an iMac running Windows.

    On a related note, my neighbor asked me to perform the normal 'cleanup / devirus / windows update' on his laptop. He owns an HP laptop and has a 'Boot up BIOS password set'. So I didnt have to enter a password each time, the first thing I did was go into the BIOS. I entered the current password and when asked for a new password, I simply hit 'Enter' and 'Enter' to confirm. When I rebooted, it still asked for a password and 'Enter' does not work. The laptop is now completely useless. I have no idea how it will be fixed. From some internet searches, supposedely I can provide HP with a magic 'system hash code' and they can tell me a password, but I have no clue if I can get through to the right person, what happens if it is outside of warranty, etc.

    Because the nature of the effort was to boot XP, they are no longer booting Windows instead of no longer booting OS X.

    Once I accidentally put an EEPROM back in the wrong way around (unforgivable with my electronics background) and the little plastic sticker which normally would cover the window (which was not actually there on this chip) blistered from the heat almost instantly. I switched it off real quick, the chip was unbearably hot to touch, but once it cooled down and I placed it the correct way around, it worked fine to my complete astonishment!
    anyone with an electronics background should know that a chip will work just fine after an overheat as long as the magic smoke hasn't been allowed to escape from it. once the magic smoke comes out of a chip, it's never quite the same
