    Someone please help. I was reinstalling a printer driver and my power cut off while it was installing. now the computer wont start and i get this message below... I read to use the install dvd but my CD drive is broke and wont take cds. I did manage to hook it up to my dads computer with target disk mode so i can access files. his computer is a windows though. i do have a copy of the Leopard install cd saved as a DMG on his computer and a 8gb flash to boot it but i cant format the flash drive to be mac extended journaled GUID from his computer.IS there a program to do this???I dont know what needs to be fixed or where i can get this acpi driver? can anyone help because i dont have any money to get this fix and i need my mac for college which im starting soon.

    you've corrupted some system file.

    somehow you have to get the leopard install dmg onto a flash/external drive. boot on your computer holding option key, select the drive, and do archive and install. no promises tho

    sounds like a kernel panic or a corrupt file system. Getting a bootable leopard disk is a must in this situation. As for a windows program that will format a bootable osx disc to a usb, i will research and see if i can find a program to do this.

    Unable to find driver for this platform Error

    I took my MacBook in to a repair shop here in town and my 1 Gig Stick of Ram was bad and causing this error. Once it was replaced, it booted just fine. I could not load the OS from the CD either, so that could have been my first clue it was the RAM. I had a 2 Gig stick also that was fine. Hope this helps someone else. :D

    iMac crashes immediately - unable to find driver for this platform acpi ioplatformexp

    I have the same problem. Just got it start up in Target Mode (hold T key while starting).

    We'll see how far I'm able to repair or reinstall Snow Leopard from my attached MacBook Pro.

    Right now, Disk Warrior is running a rebuild of the iMac's hard drive.

    We shall see...

    This is the very reason why EVERY Mac user should have a second, BOOTABLE, external drive. For emergencies just like this one.

    A "time machine" backup won't do, because it's not bootable. You need a BOOTABLE CLONE of your internal drive.

    These are amazingly easy to create, and not expensive, either.

    Can you afford $20-25 or so?
    Go here:
    http://www.amazon.com/mn/search/?re...aps&field-keywords=usb sata dock&x=0&y=0&rd=1
    (many items shown, all work the same, pick one you like that's cheap)

    Then, get a "bare SATA hard drive" from the vendor of your choice (I like newegg). You can even use an old one or a spare if you have one available.

    Then, get the FREE "CarbonCopyCloner" app from:
    http://bombich.com/

    Hook the dock to the Mac, put the drive in, turn it on, initialize it with Disk Utility, and then use CCC to "clone" the contents of your main drive to the docked drive.

    You will then have a bootable clone that you can reach for in a moment of extreme need (like the one you're having now). You can boot from your backup and work on the problems on your internal drive. If your backup is current, and your internal drive is dead or seems un-repairable, you can install a fresh drive (if necessary), and/or "re-clone" your backup back to your internal drive, restoring it.

    You CAN'T do this with Time Machine -- again, a TM backup isn't bootable and is all-but useless if you can't get your Mac booted up in the first place.

    This advice might not help with your current troubles, but it WILL prevent you from being up against the wall like this in the future....
