    Hey folks,

    I'm using OSX Tiger, OSX Leopard, MorphOS, and VoidPPC on my Powerbook. I'm finding that grub2, the installed bootloader, doesn't play nice with OSX/MorphOS. Has anyone successfully gotten this to work? The built-in OF bootloader screen is painfully slow. Furthermore, when I have my USB mouse/keyboard plugged in, they aren't recognized early enough to launch the early boot screen.

    grub2 won't autodetect the MorphOS kernel. You have to read the grub2 docs on how to add boot entries manually. On OF-systems the kernel is the 'blessed' file on the small hfs partition.

    This should work without hassles as the kernel seems to be (is?) a regular ELF-executable which grub2 is able to load manually. Don't know whether this is true for OS X kernel too.

    Have not tried it myself yet, still on my to do list. ;-)

    I’ve been able to manually add the entry for MorphOS, I’m just unsure how to actually load it. I’ll work on this more today...spent a good four hours last night until about 2am and didn’t get far so I’ll take another look :P

    Thanks!

    Ah, nice. That does solve the slow OF bootloader screen. :) Thanks!

    The issues that I still have are basically:
    1. How would I be able to always boot to this screen? KVM connected USB devices aren't recognized immediately and I can't get to this screen without plugging an independent USB device.
    2. I have a Mac Mini G4 that boots into OS9 natively. When I do that (boot into OS9), MorphOS's "bless" status goes away. That renders the OF early boot menu basically useless as it pertains to booting MorphOS. When this happens, I have to manually go bless MorphOS to make it again recognized. Any way to deal with this issue spring to mind?
