 This will likely not work if you want to boot off a SCSI drive. When you
use hdX it looks for the Xth partition on the first IDE drive. Here's what
I would do with a SCSI drive:

 If you have MacOS X or 9.X on that drive, boot into that OS and select it
as the boot partition with the Startup Disk utility. Then reboot your
machine with the following keys down: opt-cmd-O-F

 This will boot you into open firmware. At the prompt type:

printenv boot-device

 you should get something like:

 /@f2000000/pci-bridge@d/AdaptecFOO/MoreFOO/0:6,:\\tbxi

 or something like that (sorry, it's been a while). If you know what
partition your MacOS is on, it shouldn't be hard to guess what you should
change this to to boot into the Linux bootloader. Set the boot device
accordingly with a command that looks something like:

setenv boot-device /@f2000000/pci-bridge@d/FOO/MOREFOO/{DeviceNum}:{partitionNum},\yaboot.tbxi

 (sorry, it has really been a long time since I have needed to do this, so
I'm not sure how accurate the above is.).

 The other solution is to boot from the install CD. Look at the disk
partitions (without changing anything), then skip to the install ybin part
and reboot.

 Hope this helps.

Cheers,

Chris
