I see two problems here. One, I don't think 1.2.1 supported the Q800.
You'll need to try something closer to -current. Second, you don't
really need 80 MB of RAM. 16 MB should be fine, so you can just mail me
that pesky extra 64 MB. ;-)

The difference between partitions is kept in flags in the MacOS partition
table. If the name indicates it's a UNIX partition, one flag says it's
a root partition, and onther indicates it's a usr partition. APS Power
Tools set them for you.

Take care,
