However 0:2 can work also.
in fact it depends on the machine. some versions of Apple OF (particularly 1.0.5) will NOT boot from a specific partition, they only accept partition 0 which really means to boot from the first partition flagged bootable. otoh some models won't boot from partition 0, and require an explicit partition number. > > On the other hand, the 'boot-file' setting requires the root partition > > and the path to the kernel, but you can usually just put the label you > > defined in quik.conf (e.g. 'Linux'). > > Yes, this should work reliably. quik seems to like getting its > settings from the config file better than from OF. generally you shouldn't need boot-file at all, but on some versions of OF some sort of garbage ends up getting passed to quik which will confuse it, so you need to set boot-file to something, the default label name is sufficent, you don't need to specify a kernel or anything. and on some models you need to set boot-file to something, but its never seen by quik anyway (beige g3s tend to be this way). > > If that doesn't work, you should > > try filling in the full path : e.g. > > "/pci/mac-io/ata0/[EMAIL PROTECTED],2/boot/vmlinux" > > (or maybe "/pci/mac-io/ata0/[EMAIL PROTECTED]:2/boot/vmlinux") not in boot-device. boot-file maybe (if quik gets confused and isn't able to load its config). > > > I've tried manually > > > exploring the device tree, and it seems like that > > > device path just does not exist there to OF (ver. > > > 2.0.1, btw).
