	Well, there's no difference (at the moment) between a ProDOS 8 and a
GS/OS partition, as they both use the ProDOS file system. You could, of course,
keep the files and programs you use for P8 & GS/OS separated...

	Unless the PC-Transporter software has changed recently, I don't think
that you can use an entire partition specifically as an MS-DOS partition. You
can, however, create a psuedo-partition with the PC-T software, where the
MS-DOS partition is actually a big ProDOS file. So, you could set up a ProDOS
partition on the drive, and have an MS-DOS partition that fills said ProDOS
partition. Of course, unless you put the Apple SCSI card in slot 5, you'll
only be able to have 2 partitions visible when you're in ProDOS 8 - this means
that you'd have to have one partition shared between the GS/OS boot volume and
your P8 files/programs, and one partition for the file that's the MS-DOS
partition (and then however many ProDOS filesystem partitions that are only
visible to GS/OS).

	I believe that currently, GS/OS allows for up to 7 partitions either
per SCSI card or per SCSI HD, so you could have 2 32Mb partitions for P8
(including the 1 partition for the MS-DOS stuff), and then, say, one 12Mb
and one 24Mb partition that are only visible to GS/OS. The last two partition
sizes really depend on what you do - I've got 3 partitions on my 64Mb drive,
named :Sys, 10Mb (system partition - system software, incl. fonts, some
temporary storage areas, and a few ProDOS 8 development systems), :Misc, 30Mb
(for all the stuff that doesn't go on the other two :), and :Dev, 24Mb (which
is where all the development stuff for the //gs goes).
