    I've got an iBook G4 1.2Ghz, and it's been running 10.3.6 fine. I decided I wanted to install Mandrakelinux on it, along with separate partitions for Jaguar and Panther versions of Mac OS X.

    I connected the iBook to my Power Mac G5 via Firewire target disk mode, and used the pdisk Unix command-line utility to format the drive's partitions.

    After hours of work and getting myself extra confused, I figured it all out, and now have Linux running on the iBook. During this process I was also doing many Open Firmware commands, some which I was entering without any idea of what they meant.

    Now I want to install 10.3 on a partition, but when I boot up from the install cd, I get the prohibitory sign, as seen here: http://docs.info.apple.com/article.html?artnum=106805

    Anybody have any idea what may have gone wrong? Did I screw up the firmware? If so, is there a way to reset it? I've reset the NVRAM/PRAM. When booting from the hard disk, I get blinking question mark, which is obvious since I have no Mac OS installed. Yet Linux works perfectly fine (I imagine because there's some OS X specific stuff that's gone?).

    Thanks.

    Sounds like you hosed your FirmWare. Not smart to play with that. I don't know how to reset it offhand...


    [Do both these things after you turn on the iBook and before you hear the startup chime]

    Try zapping the PRAM, Command+Option+P+R
    OR
    Try holding C when attempting to start up off the OS X install disk.

    You can't do both on the same startup attempt...

    EDIT: The newer computers that are sold with Panther pre-installed are supposed to be Panther and up only. That may/may not be true, but unless you are developing software you don't need to do that. Just wondering...WHAT THE HECK WERE YOU THINKING? :confused: :confused:

    Nothing personal, just really confused...

    Thanks for the reply.

    Like I mentioned, I've already reset the PRAM and have tried numerous times to boot up from the cd, without success.

    Not sure what to do from here...I don't think it's a hard drive issue since I can get Linux running fine. Oh well I'lll keep searching :)

    I had the same problem as you had awhile back. The problem was that yaboot changed the name on the bootstrap partition.
    Use pdisk and see if there is a partition called "Apple_bootstrap", if thats the case, change the name on the partition to "Apple_partition_map"

    In all the PPC Linux installs I've seen I've never seen anyone mention messing around with OpenFirmware. In fact if they did I wouldn't do it - you can really, really screw your machine up that way.

    suddenly i'm remembered about the article in a PC magazine about hot swpapping BIOS chips...

    messing with the bios is always a dangerous game.... i hope a solutions turns out for you...

    Yes I reset it via OF.

    Is there any way to reset the firmware? The first time I installed Linux, it said that I had to enter this command because the bootloader wasn't correctly installed:

    setenv boot-device /pci@f4000000/ata-6@d/disk@0:2,\\:tbxi

    Did that screw it up?

    I am able to enter "printenv" and get a list of all the OF variable and their contents. Anybody know any variables that should be "this" and not "that" ?

    hm i have no idea of Open Firmware but it looks very much that that _might_ be the error source ...

    have you tried the link psoted by pncc where they have some firmware command "reset-all" (or something like that) that sounds a lot like resetting to default... but i'm only guessing

    Well guess what?

    The problem is NOTHING to do with my computer, but the OS X cd I was using. I guess the newer iBook G4's only boot a certain OS version, and using the iBook's system cd's (Mac OS 10.3.5), it boots perfectly fine into the OS!!! What a simple fix for what appeared to be a huge problem!! Thanks all for the help!
