[comp.sys.ibm.pc] Some of this, some of that

I have just added an Irwin 10MB tape drive to my system, only to realize
while running SETUP [ yes, I ran Messy-DOS.  I'm so ashamed ... ] that
the tape was being configured as my second floppy disk.  Trouble is, I
want to add a second floppy drive as well.

What can I do to get around this?  Does the floppy controller support
more than two devices?  What about more than two floppy controllers?
And would Xenix support that?

The only alternative is to buy a non-floppy controlled tape.  Which is
a lousey idea because the Irwin was free ...

What I have done with Irwin tape drives is to put  a  switch
on  the Irwin and floppy select jumper lines.  The switch in
one position will select the floppy and in the other it will
select  the tape drive.  It worked nicely.  Now all you have
to do is figure how to plug three drives into a  data  cable
made for two :-).

You haven't mentioned what system you're running, so it's hard to answer
your question.  I have 8 floppy disk drives on an XT clone, so it's
definitely possible to have more than 2 drives.  It should work with an
AT too.

The Micro Solutions Compaticard is an 8-bit bus type disk controller
that can co-exist with your standard IBM type floppy disk controller,
and you can have up to 4 controllers total (for 16 drives).  The 4 drive
version is $ 175, and a 2 drive version is available for $ 125.

The standard XT type floppy disk controller can support 4 diskette
drives standard, but it doesn't support high density drives.

The Compaticard comes with software for MS-DOS, but I don't know
of any Xenix device drivers for it.
