No netboot, no ofwboot.xcf on CD, etc. Yeah, I should probably include yaboot to make it complete..."

    "leia" (the iMac that built NetBSD/macppc 1.4.2) has had its HD divided into MacOS and NetBSD areas for quite some time, but I never did figure out how to run ofwboot from HFS. I just kept netbooting ofwboot and entering the local path to the kernel.

    My hat is off to you, sir.

    Can I moderate this down on the grounds that it's posted by a cron job?

    Incidentally, this same thing works for OpenBSD. I was playing around with that on my own iMac for a little while.

    ...to dual-boot MacOS and BSD. It's called MacOS X.

  5. On an iMac? by ZigMonty · · Score: 2, Insightful
    What's the point in dual booting NetBSD and MacOS on an iMac? Get MacOSX which has MacOS Classic, all that bsd stuff, x windows if you download it and a whole bunch of other stuff that isn't in the NetBSD+MacOS combo. Now, if it was a machine that didn't support MacOSX I'd understand.

    It IS cool that it's possible though.

      My iMac only has 96M RAM, which kind of rules out Mac OS X. I had Darwin on it for a while, but I still prefer NetBSD.

      because it can be done and its fun to try.

      you're on slashdot, you shouldn't need any more reason. in any point OSX is not exactly ultra fast on a G3 box

    Especially if the different OSes can access each others' partitions, it might make troubleshooting easier.

    Mac OS X can read UFS partitions natively. You can install to a UFS root volume, but apparently there are a couple of bugs with some apps running on UFS, and classic Mac OS can't read UFS, so it's not recommended for average users.

    One of the biggest noticeable differences: UFS is case-sensitive; HFS+ is case-insensitive (although it does preserve case). This means two files whose names differ only by case cannot exist in the same directory. This breaks some UNIX stuff that expects "Makefile" and "makefile" to be two different files; on HFS+ they are the same file.
