G5 PowerMac dual-boot

[Terence Parker <terence@parker.com.hk>]

I'm trying to get my G5 system to dual-boot linux & Mac OS X (the usual story I guess), except that i'm having some problems getting into OS X.

Contrary to most documentation about yaboot, in my setup I have OS X in my first SATA drive (dev/sda3 - for some odd reason) and have installed linux on my secondary SATA drive (/dev/sdb5). My yaboot.conf is as follows:

boot=/dev/sdb2
device=/ht@0,f2000000/pci@7/k2-sata-root@c/k2-sata@1/disk@0:
timeout=20
default=macosx
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot

image=/boot/kernel-2.6.11-gentoo-r8
        label=Linux
        partition=5
        root=/dev/sdb5
        read-only

macosx=hd:3

Most of this was auto-created by the yabootconfig script, but I manually shuffled some options around and have added the macosx=hd:3 option. I have also tried specifying macosx=/dev/sda3 - also did not work.

Though I don't know how this works, I am guessing that it's trying to boot OS X off the same "device" that was defined for my Linux OS and therefore that's why it can't find it? I get an error saying 'invalid or corrupt image' (I can't remember the exact error) - but I do see the long device string in my config line appearing in the Yaboot menu command prompt.

I would be most grateful if someone could enlighten me!

Many thanks,

Terence
