SeeHere Level 1 Level 1
I have read many posts, but no posts resolve this issue. With wiped or new hard drives, the operating system install dvd disk fails to install and hangs with a last line panic message repeatably mentioned by others and now me "We are hanging here..."
I have a quad core G5 with a wiped and new hard drive. When using a powermac G5 install of the manufactured time of the machine, the install hangs. The install is 10.4. What was on the hard drive before it was wiped was 10.5. I have tried several different disks all with same result. I have done all the obvious and previously failed thing: pulled the battery, reset PRAM, tried different hard drives, other dvd drives, etc. I read that Apple claims to many that the logic board or processors are bad and to throw out the units.
+*Here is the twist.*+ I have four of these units. Prior to wiping they hard drives, they all were in perfect working order. I have 16 more that have not had the hard drives wiped, and all behave exactly the same way when I try to install the operating system while booting off the DVD install disk. If I launch the install disk from the systems when the systems are happily running, they too fail with exactly the same message. I therefore doubt that hardware is at fault and that they all suddenly have bad logic boards, then good, then bad. Or that they are all breaking at the same time when every single one of them were working fine everyday.
I want to get the ones with the wiped drives up and running again. I don't want to put the systems from the unwiped ones on the wiped ones.
Interesting isn't it? Very I think. How much good hardware has been wasted by this issue?
Any ideas? Please, put on your thinking caps.

Power Mac G5, Mac OS X (10.4.11), Quad Core

    My only guess is that installing 10.5 might have updated the firmware and that the new firmware is not compatible with 10.4.

    Hi SeeHere, and a warm welcome to the forums!

    I don't want to put the systems from the unwiped ones on the wiped ones.


    I fail to understand why you'd not want to try tat on at least one using FireWire target disk mode...

    And using carbon copy cloner to make an exact copy of your old HD...

    Or SuperDuper...

    What OS/Mac did you use to do that?

    In Disc Utility>blue Info icon, what Format & Partition scheme is reported?

    I do feel sorry for the many that have just one of these G5 towers and think the problem is hardware. I have four advantages over them: 1) I know it is not the hardware 2) I have a few machines that have not been wiped and still function 3) Others in my group (I am a university professor) are in the same boat and are also puzzling with this issue (around 100 machines are doing this) 4) I have people like you. Thanks for your response to my problem.
    The G5 quad I am working with is home. The rest are 40 miles away, at work. I will try what you suggested Monday or Tuesday and get back here. I think you suggestion might work. Still how about all those who don't know that this is some kind of software/firmware glitch? The web is poxed with post about this issue.
    I have an older, first generation Powermac G5 tower here at home that has the latest of the 10.4, 10.4.11. Would it make sense to use its system as a target firewire disk? Thanks.

    The Quad req'd 10.4.4 if I am not mistaken, there were retail 10.4.3 and then the last retail version was 10.4.6. What you want is OEM or retail and 10.5 would be easier to come by.

    The only stealth firmware updates are generally to optical drives, Apple OEM or one that is same make/model. Not to system and there is a list but I can't recall Open Firmware getting one, and SMC firmware updates are also rare (maybe once per product cycle).

    A uni tech wiped it so i don't know about what was used to do it.
    The startup DVD system disk give two choices 1) mac system 2) hardware test.
    The system disk does a gray apple logo then a list or events ending as described in the first post.
    The hardware test choice reports that this systems hardware is not supported by the disk. Just got this info from efforts this morning. Is this useful at all?

    Thanks, The Hatter. So it is doubtful it is a firmware problem.
    The DVD System disk I am using:

    Hi-

    A 10.4 disc won't work with the dual core Late 2005 machines.

    Here is a list of shipping builds for each machine. Note that some machines in a series will ship with a later version as it became available.

    I will attempt to find a newer os at work tomorrow. This is promising. The tech that install systems at my uni just throw the systems disks into a pile or discard them. Likely they gave me the wrong disks to install from.

    I will get back here to report.

    Very useful like and thanks japamac.
    I will attempt to find a system DVD that conforms tomorrow.

    Wrong disc, not intended for that Mac.

    Apple has been known to ship a new set for a small fee, so you can have AHT at the least, if you can't dig up and find the originals (they just need the serial number of the Quad).

    If you wanted to try to boot another G5 from it's Disk, then yes, but if you want to clone it's HD to another G5, then have the other G5 in Target mode.
