    My brand new power mac G5 needs an OS to boot from, and when I put in the osx server disc it just kernel panics. When I put in A regular leopard disc it does not even read it.

    Is the Leopard disc a retail disc?

    What version of OSX server?

    If it's not the discs you may need to try a different optical drive.

    Retail? Have you used these disks before?

    I have not used the discs before. I got them off ebay.

    Your Quad 2.5 Power Mac has a DVD drive that could read dual layer discs, and since it's doing a kernel panic on the Server Disc, that would rule out a DVD drive problem, at least to me.

    Is that Leopard disc a retail disc? Meaning it's black (retail). If it's gray, which is what the system specific discs are, which will not work with your PM and would eject just like you are experiencing. It shipped with Tiger so there are no Leopard system discs for that machine, any Leopard system discs you might find/buy would be for other Macs and not work.

    First I would reseat all of the RAM and try again. Make sure it's all pushed in firmly and the tabs are secured. If that doesn't solve the problem I would start taking RAM out and only leave one matched pair in place and see if you can install Server. (Server is your preferred OS, correct?)

    Kernel panics indicate a hardware failure. Most of the time it's RAM. either it's badly seated and can be pushed back into place or one stick or more has failed (or even a RAM slot has gone bad). Take all of the RAM out but one set. Try it, it if doesn't work, replace that RAM with some of the other RAM and keep note of what's what. Keep the matched pairs together.

    If you can't solve the problem with the RAM, it's likely a different piece of hardware. It could be the hard drive, the logic board, the power supply, etc.

    Check to make sure all of the cables are firmly seated on both ends.

    Yes, it is a black retail disc.

    Most of the Kernel Panics are not HW problems, most of the time there are OS issues or in rare cases Application incompatibilities (One version of Transmission for instance gave kernel panics).

    His issue is most likely an incompatible OS Install disk.

    Or RAM issues, as we've been discussing in this thread, which is a HARDWARE problem.

    He has a retail Leopard disc, which was posted before you replied.

    Apple has an entire thread on HARDWARE kernel panics.


    OP, do you have another Mac to put that Leopard disc in and see if it is recognized?

    I was having a similar struggle with my G5 that I picked up a few weeks ago. Have you reset the SMU (or PMU)? I was receiving endless Kernel panics and a simple reset cleared everything up. If you are still struggling, might I suggest trying Target Disk Mode (if you have another Mac). http://support.apple.com/kb/HT1661?viewlocale=en_US&locale=en_US

    I have solved the issue. An incompatible SATA controller was causing the kernel panics.
