Chain booting error?


This means chain0 was either unable to locate the Mac OS X partition or unable to load (and verify) the partition's boot sector. Chain0 doesn't bother about whether the partition is marked as bootable, but checks partition type and a valid first sector on it.

First, ensure the partition is of type 0xaf (HFS+). Types 0xab (boot2) and 0xa8 (UFS) would be accepted by chain0 as well, but the type should match the actual contents of the partition. Linux fdisk can view and change partition types.

If this fits, check wether your partition has a valid boot sector (= first sector of the partition). Without going too much into the details, this worked from a Mac OS X installed in VMware for me after unmounting the partition (Mac OS X speech: Dragging the Volume to the trash):

sudo dd if=/dev/disk1s2 of=block1 bs=512 count=1
hexdump -x block1

The last two bytes should read "AA55". Else, the boot sector of the partition won't be accepted by chain0.

You can copy over the partition boot sector over from /usr/standalone/i386/boot1h, of course. Often, this won't help much, though. If your installation lacks a valid boot sector, likely something else went wrong as well, and you should verify wether you use the correct installation procedure.

Once chain0 has loaded and verified a valid partition boot sector, chainO hands control over to it: End of chain0's part of the game.


Additional experiences:

If it's still not working, make sure your Mac OS X partition (af) is not UNDER an extended partition. It also has to be a PRIMARY partition. While chain0's source code indicates support for extended/logical partitions, experiences obviously show a different picture.
