I too have an XP150 and it works very well (it's faster, and bigger than
a quantum 80 ...). What I did was the following (it should work for any
CDC Wren IV based disk and also for many other similar disks), I dd'd
the whole of the Apple distribution from a quantum (ie dd if=/dev/rdsk/c0d0s31
of=/dev/rdsk/c1d0s31 bs=500k) to my XP150, this copies EVERYTHING including
all the partitions, the partition table, the HFS booting partition and the
APPLE driver. I then used dp to extend the 2 sector 'Extra' partition at the
end so that it takes up the whole of the rest of the disk (make sure you set
the partition type correctly to 'SVR2 user'). Next I used pname to call the
partition /dev/dsk/c1d0s2 and the used mkfs to put a filesystem on it. You can
now reboot onto your new disk, after coming up single user mode use pname to
create an /etc/ptab (so it always recognises the new partition) and then
create a mount point and add an /etc/fstab entry so that the partition will be 
mounted when you go multi-user. Phew easy wasn't it :-) of course you only
have to do it once.

The SuperMac (MacOS only, A/UX has its own) driver on the original XP150
doesn't seem to support partitioning correctly, they tell me they will fix
it asap ... this is a pity for two reasons 1) it is faster in its transfer
rate than the Apple one (leaner and meaner) but if you only run A/UX this
is not an issue and 2) it has special hooks in it which allow you to run all
those free programs you got on the disk when you bought it they are 'copy
protected' so that they will ONLY run off a disk that is running with the SM
driver (after all they did come FREE with the disk). Older XP150s or XP150i
(the internal disk) owners may need a ROM upgrade to run with A/UX, see 
SuperMac for details.

Disclaimer: I have business dealings with SuperMac so I'm probably biased
	but the above information will hopefully help anyone trying to
	configure a 3rd party disk with A/UX
