    Thanks for the tip. It works for 1 of my installs. It fails on 2 others on the same machine. I can boot the other 2 with an osx install disk in the cd and changing the order of drives in the bios. Kind of a pain but it does work in a bind.
    I am sure there is something missing in the boot sector of the partitions that wont boot on there own.
    The disk that boots is a small 10G and the installer installed with no problem. The other 2 I had to work to get them reconized and installed. I expect they didn't get blessed properly. The bless command was missing. I got it some were. But I can't seem to get it to work yet. Not sure I am issuing the command correctly but I have read many examples and it nevers seems to work. Start disk in prefs crashes when I try to use that.
    Here is my grub menu.lst

    title Fedora Core (2.6.17-1.2174_FC5)
    root (hd0,0)
    kernel /boot/vmlinuz-2.6.17-1.2174_FC5 ro root=/dev/sda1 3
    initrd /boot/initrd-2.6.17-1.2174_FC5.img
    title OSX86 Jas 10.4.7 (Works. Darwin bootloader boots corectly)
    root (hd3,1)
    chainloader +1
    boot
    title OSX86Too
    root (hd0,1)
    chainloader -- force +1
    boot
    title OSXx86
    root (hd1,1)
    chainloader +1
    boot

    I have tried with and without --force on both drives. With --force it seems to be looking a specific file. Do I need to add a path to some thing? Without --force it ssay some thing about bad executable format.
    I think grub may be able to setup the partition but I don think it can deal with HPFS+. Maybe it doesn't need to because it works at a lower level? I am not sure what file to try to load to it. Maybe chain0?
    The partitions are active and will boot from the DVD.
    The only disk i can see if I boot int the install is the 10g. The others are not available because they need some hacking on AppleVIAATA.kext. Is there a way to modify the install disk to include the hacks?

    Thanks for looking and any help.

    Try putting makeactive before the chainloader line.

    Thanks I tried that also. It seems there is some thing missing in the partition setup. There must be a bootloader at the front of the one that works. I think that is what the bless command does. If I could get that right i think it will work.

    I also tried the bootable rsync mentioned here some where. No luck.

    OK after some more research I think the file should be boot1h. Anybody know how to insert it into the boot sector under osx? Can I do it under linux? Fedora mounts hfs+ read only.

    Any one know of a freeware program to work with boot sectors under osx?

    thanks Don

    In order to mount it under Linux (with write permission), you must first disable journaling. To do it, use Disk Utility or type in the terminal: diskutil disableJournal <device>

    Disk Utility can only ENable journaling, for disabling you really either need to use terminal: diskutil disableJournal <device>, or, if you prefer a GUI tool, use Cocktail.

    Thanks. I used the command line and removed journaling. Grub still does not like HFS+. I tried grub2 which is suposed to be implementing support but it is not there yet. May try CVS version later.
    Is the bless command the normal way to do this under Apple systems. Or is diskutil the way to go? I seem to have problems with both.
    The problem stems from the install disk not reading my disks without modifying Appleviaata.kext. Is there a way to modify the install disk? I think I could use the files from the working system if i could fogure out how to modify an image under OSX. I tried toast but do not see how to do it. Is there a better program or am I missing some thing in toast? It also seems to be a special type with 2 file systems. Not sure how to deal with that.
    Maybe i should have started a new thread but I thought this would be a quick answer. What section should I put it under?

    I tried to boot Darwin 8.0.1. It boots but can't see my drives. Same boot loader as the install disk so not a real surprise.

    Thanks Don

    I just want to eliminate a possible problem here.

    From your menu.lst, this is your setup:

    Fedora on first disk, first partition (sda1, or (hd0,0))
    OSX86 Jas 10.4.7 on fourth disk, second partition (hd3,1)
    OSX86Too on first disk, second partition (hd0,1)
    OSXx86 on second disk, second partition (hd1,1)

    Am I correct?
    It's just that it wouldn't be the first time that one forgets that the first partition's index is "0" and not "1" in the (hdx,y) notation.
    (I also assume that all the osx partitions are primary (and you already said they were active)).

    Am quite sure this isn't the problem and you did it correctly (since osx on hd3,1 boots).
    Just wanted to get that out of the way.
