I have an XP150 (Wren IV based), I just did a:

	dd if=/dev/rdsk/c0d0s31 of=/dev/rdsk/c1d0s31 bs=400k

(where the distribution disk has scsi ID 0 and the Wren has ID 1). This copies
over the partition map, Apple driver and the whole distribution. The Apple
driver works just fine. After you have done this you will want to use
the A/UX utility dp to enlarge the last partition in the partition map
to take up the whole of the rest of the disk (dp will tell you how big
the disk is). Next use pname to give the new partition a minor number
(ie attach it to /dev/rdsk/c?d0s?), next use mkfs to put a file system on it
(you should also use pname to make an /etc/ptab ...)
