An RX33 is a 1.2mb 5.25" floppy drive. Actually, I guess I just didn't
think hard enough. When I didn't have *any* set commands, the drives
were automatically assigned DU0=RD54 and DU1=RX33. My guess then is that
the RD54 is unit 0 and the RX33 is unit 1. The suggests that if I just
add the line:
set du4 unit=1
I should get the RX33 assigned to DU4:
I guess I should think before I type in questions. Sorry!
Typically, one would do
set du0 unit=0 part=0
set du1 unit=1 part=0
set du2 unit=2 part=0
set du3 unit=3 part=0
so that all your physical units map to the device units in a way you
expect... then you add the alternate partitions:
set du4 unit=0 part=1
set du5 unit=0 part=2
set du6 unit=0 part=3
set du7 unit=0 part=4
or whatever you need to get at the other partitions on an RD drive.
Or, you could use the 64-bit version of the driver, in which case you
have units D00 - D77 (octal unit numbers)... I leave the mapping of
ports, units and partitions to you... I can't keep that many straight in
my head...

Okay, I think I see how to do it:
set du0 unit=0, part=0
set du1 unit=0, part=1
set du2 unit=0, part=2
set du3 unit=0, part=3
Yes, that looks familiar.
If I do this, I wonder where my RX33 will be
assigned. Is it assigned
du4 since du0-3 are already taken by partitions?
Hm....
Every MSCP device has a device number. And you have to tell the driver
on which device number and partition it should work.
So if your RX33 (what IS that??) has unit number 0, you can create the
devices as above. If you have different drives, you have to use unit=x.
