[Coco] Multipak and Drivewire

[Michael Brant]

I have an MPI, I also have a CoCoSDC, along with two FD502s (one stock and
one with HDB-DOS.)
Both the SDC-DOS and HDB-DOS allow me to use Drivewire (which I connect to
DW3 on my Mac Pro.)
The question is this how (if possible) does the system assign disk numbers
and drive numbers?

So far I have used the drive function but when doing so, I it seems to
cutoff access to the DW and only access physical disks.

I am fairly new to DW and MPI usage, my old CoCo days did not have an MPI.
