First, you can boot into Open Firmware by holding down the
option-command-O-F keys while the system is rebooting.
Once in Open Firmware, you can issue the boot command to tell
it to boot from a specific partition on one of your hard drives.
You can also use the setenv command to make Open Firmware boot
from a specific parition every time your system reboots. That
will work until you change the "Startup Device" under Mac OS X;
for some reason, this command reprograms Open Firmware's memory.
In a moment, I will list the commands I use for my PowerBook (pismo).
Since you have a cube, your drive partitioning may be a bit different
(you can always boot from your YDL CD and use the df command to
figure out how your Linux drives are numbered).
Here goes:
To boot yaboot, which is installed on partition 10 of my
internal hard drive, I issue the command:
boot hd:10,yaboot
To reset my boot device so that my PowerBook will always
boot with yaboot, I usse the commands:
setenv boot-device hd:10,ofboot.b
reset-all
You can learn lots more about Open Firmware by visiting Apple's
Tech Info Library.
