Anyway, here is my plan for multiboot:
root@kg-g5# gpart show ad0
=> 18 625142430 ad0 APM (298G)
18 1600 1 apple-boot (800K)
1618 155189248 2 freebsd-ufs (74G)
155190866 8388608 3 freebsd-swap (4.0G)
163579474 1600 4 apple-boot (800K)
163581074 155189248 5 freebsd-ufs (74G)
318770322 306372126 - free - (146G)
The boot code in partition 4 (ad0s5) will be modified so that it boots from
the next partition (the partition after the one the bootcode itself is loaded from)
instead of the first partition. Do you think it's doable?
I have examined boot1.c (in /usr/src/sys/boot/powerpc/boot1.chrp) but I don't
really understand how it is finding the partition to boot / load the kernel from.
Can anyone explain it?
