    Hello everybody!
    Someone could explain me (maybe I'm acting wrong :-) ) why this thing happens when I try to install MorphOS 2.6 on PowerMac.
    I followed the Jacadcaps guide and created seven partitions on my 160 giga hd, due to install:
    MorphOS boot.img and Linix bootloader (two 30 meg partitions)
    MorphOS main (Apps, Prefs etc.)
    MorphOS Work
    Mac OS X
    Linux
    Swap for Linux
    When I launch IWizard and I arrive at partition section, something strange happens: partitions are doubled and I have four 30 meg partitions, two MorphOS partitions and so on. Partitions are 14!!! Excluding the 128 kb partitions...
    Grab 1
    and if i try to select one of them....
    Grab 2
    (partition layout not valid!)
    Closing IWizard and opening HDConfig everything is ok:
    Grab 3
    and is possible to select a partition without errors:
    Grab 4
    The problem is I cannot install anything since IWizard stops there as I cannot select a valid partition for MorphOS.
    Is there something I'm acting wrong?
    Thanks for any help!

    We're aware that Mac partition layout support in HDConfig needs work. Hopefully things will be fixed at some point.

    Btw, you did not mention which app you used to create the partitions. Try a different one perhaps.

    I had this prolem partitioning my hd via MacOS X 10.4. I've resolved deleting manually under Morphos via Hdconfig the duplicated partitions.
    All now is working fine doouble booting MOS and OSX.
    Sorry not be able to be more precise but I'm writing this at work.

    @Jacadcaps:
    Thanks for the info! I used Utility Disk under Mac OS X 10.4. I will try another way.
    @ Maurensen:
    Thanks to you too! But the problem is: with HDConfig the duplicated partitions disappear (as you can see in the Grab 3) and everything is normal. How to delete them?!? From IWizard I did it in a previous installation and this created problems with all the other partitions, since I didn't/don't know wich is the right one to erase.

    I'm not sure, but could this issue related to the limited ATA driver in OSX on older Powermac G4? The models before MDD IIRC could only use upto 128 GB harddrive on the internal ATA bus, without using a third-party driver. Maybe there is an issue in mixing the OSX partition scheme with the MorphOS partition scheme.

    There's no 'mixing' involved. MorphOS uses the standard PPC Mac partition layout.

    @jacadcaps:

    I meant "mixing" regarding the harddisk size. MorphOS (and Linux) sees the whole 160gig drive, whereas OSX (may) only see 128 gig. I had some problems with it.

    See this:

    http://support.apple.com/kb/HT2544?viewlocale=en_US

    Summary
    Not all Macintosh products can take advantage of the full capacity of large (128 GB or greater) hard drives that use 48-bit LBA when they are connected via an ATA controller. Other controllers (SCSI or FireWire) are not affected.
    There are two primary requirements that must be met for higher capacity hard drives to be fully utilized within a computer.
    1. The computer must have Mac OS X 10.2 or later.
    2. The computer must provide support for the drives via the BootROM.
    The BootROM of Power Mac G4 (Mirrored Drive Doors), Xserve, Power Mac G5, and any other model introduced after June 2002 can accommodate these larger drives.

    Ok, maybe there's some kind of misunderstanding, or I just couldn't express how it was meant to be. It was just "a shot in the dark".

    This is what I've done under OSX:
    - create 5 partitions
    1st boot.img HFS
    2 morphos
    3 Work
    4 Mos partition
    5 temp partition (FAT32 to exchange datas)

    Then install OSX int the 4th partition disabling OS9 support.
    Now boot mos Cd, start Iwizard and you see all partition duplicated (also the 128mb dummy partitions).
    Simply delete one of the two duplicated partitions (also the 128mbs) under Iwizard and save.
    Now you should see the whole thing ok under HDconfig(that worked for my MDD 1.25ghz).
    p.s.: I've also noticed under IWizard that if I change the file system of the partition the program wrongly report HFS+ no matter what FS chose.
    I'm at work and I've made this last week so my memory may be a little inaccuate :-)

    No, PowerMac G4 FW800 and MDD can use PATA hd 500gb.
    The """limit""" default 128gb It's in older PowerMac models

    Isn't "older PowerMac models" = "models before MDD"?

    Thanks to Maurensen, I solved this mistery... ;-)
    Followed the instructions bring me to finsh the installation and now MorphOS is on the hard disk. =)

    @Divinity:

    As Andreas wrote, the models before MDD have got this limit (Quicksilver, DigitalAudio, Gigabit, AGP). This limit affects only OSX and OS9, with MorphOS and Linux being able to use > 128GB.

    So you've got a MDD?

    Actually, I wrote that the models before Quicksilver 2002 have got this limit:

    First, see Andreas comment.
    Second, I agree that Linux distros appear to handle larger disks on older Powermacs (at least it works on my original Quicksilver - which can fully use my 250GB drive).
    Third when installing MorphOS I deleated all partitions and wound up with a 128GB partition (appears to be a limit).
    I probably going to install additional drives (or a larger hard disk) and repartition and re-install MorphOS and Ubuntu.

    I'm sure MorphOS can support >128GB partitions on older Powermacs, but I'm not sure I can use 2.6's partitioning tools to do it.

    Yes, with SFS that's the limit.

    @Jim

    MorphOS supports >128GB partitions just fine, but the default filesystem (SFS) does not. So you either have to create several sub-128GB partitions or use a different FS.

    @ Andreas & jacadcaps,

    Thanks gentlemen, you've confirmed what I suspected. When I do re-format (which I mainly need due to an error during the instillation of the Ultimate Pack), I'll do what I did initially. Install MorphOS and then letr grub resize the remaining space for its Ubuntu's partitions.
