Thanks for the info. So if yaboot is on the internal drive already
then yaboot can get to an external drive as easily as internal, right?
I'm thinking is sort of like

/dev/sda is the internal drive with it's OS x partitions. Yaboot is there.

/dev/sdb is my external 1394 drive. Tell yaboot to go there and it
finds a Gentoo kernel to boot? Or is it more complicated? Does yaboot
want to find an Apple kernel to jump to?

An individual on the gentoo-ppc channel pointed me here:

http://hansmi.ch/articles/boot-linux-from-firewire

He suggested all of this stuff is possible. Seems pretty cool.

The reason I'm interested is that I could use the 1394 drive as a data
drive running Ardour and do my tracking under x86 Gentoo. Later I
could move the drive to the Mac Mini and do my mix down under either
Gentoo or OS X. One drive - two machines - three OS's. Fun.

thanks,
Mark
