no, you wouldnt be able to do a pr#x because there is no actual drive firmware 
in those slots, its just prodos8 playing tricks on itself, 
theoreticaly once you have p8 running, you can 'prefix /aux'
then execute (-prodos) the prodos startup code, but gsos
doesnt seem to like that and crashes on my system..
there is hope! never fear! i remember a program called "swapscsi"
that swaps out the volume partitions on your drive,
so that any partition can be moved into the first position.

its not on archie, so i must have gotten it from genie...
heres part of the doc file, ill post them to the binaries if
anyone wants them..

Enclosed is the first issue of 'SWAPSCSI', an added Basic.System (ProDOS 8)
command that allows the user to swap logical drives (volumes) around on a
given _REV C_ Apple SCSI card.  It can only be used with the Rev C Apple
SCSI card, and provides a means for Apple ProDOS 8 users to access other
volumes on a hard drive with more than two partitions.  Only two volumes
can be active at one time in any given slot, but by swapping drive 1 or 2
with other 'drives', it's possible to easily access any volume on the disk
and manipulate it individually or in conjunction with any of the other
volumes.  And a 'ReInit' is available to save the befuddled user.  This is
how it works:

Add the command to ProDOS by BRUNing SWAPSCSI or -SWAPSCSI.  This installs the
new command into Basic.System for ProDOS.  It is important to note that this is
not a stand alone routine.  It is a user addition to Basic.System, like Glen
Bredon's ProCommand package.  However, once the user has made any desired
changes to the volumes, he can leave Basic.System, and the changes will remain
in place until he turns his computer off or somehow reINITs the SCSI card.
Besides allowing the user to swap any two SCSI 'drives' with one another, this
command also provides a means to INIT the SCSI card, so that it is easy to
return all the volume info to its standard setup.
