No, the minimyth kernel doesn't support EFT/GPT partitioned disks. It also doesn't support SATA hard drives. Currently, it doesn't even know the hard-drive is there. If it did, it wouldn't know what to do with it. > You can put an hfs+ partition on a msdos disk, or a fat32 > partition on a gpt disk and grub.efi can handle both. plus > linux ext2/3. Right, but the MiniMyth kenel can only handle msdos parition tables, and Macs will only boot from GPT partioned disks. > Have you installed the rEFIt boot manager > http://refit.sourceforge.net/ It simplifies testing and the > web site has good information on Apple efi booting and some > history.

One thing that's confusing it talks a lot about "the volume" -- always in the singular. I can't figure out to what "volume" refers such that there is never more than one in a system. > Seems to me the key issue is getting your kernel and system > running, identity any grub development issues, the other stuff > can be optimised later. At this point, there aren't any grub development issues. Grub works fine. The current issues are caused by: 1) Mac firmware not being able to boot from anything other than an HFS+ partion on a GPT partioned drive. 2) MiniMyth kernel lacks support for EFI/GPT parition tables and SATA hard drives. I'm going to try rebuilding MiniMyth with GPT support so that I can GPT partition a USB flash drive in hopes of getting the Mac to boot from it. I'm also going to try adding AHCI SATA controller support to MiniMyth so that I can spin down the hard-drive. > My experience has been with other users of Apple Intel Macs > bootng Debian/Ubuntu linux and Mac OSX, using grub-pc and > grub-efi.

So far, that's not been possible, but I'm getting closer. -- Grant Edwards grante Yow!
