    Hi

    My G5 dual core (late 2005) is giving me real problems.

    I have tried all the basics, resetting PMU, PRAM etc. changing RAM but still the same Kerenel Panic on start up.

    I want to instal tiger from installation DVD, the hard drive on the G5 has been reformatted because it was showing errors and I thought that was the cause of the problem. Now i can't even boot form the DVD.

    here is what it says..

    Try starting while holding the Command-Option-Shift-Delete keys all at the same time and see if it will let you startup/install.

    Do you have any external drives you could install Tiger on first?

    If the above doesn't work, try this:

    1. Start Mac and hold Option-Command-O-F keys
    2. When the grey screen gets loaded type reset-nvram then press Return key
    3. At next prompt type reset-all and the Mac will restart

    See if that will allow install.
