I originally had 2 360K's in my XT clone, and I replaced the b: drive with
a 1.44M.  I bought a clone-ish supermulti i/o card, that has 2 ser, 1 par, 1
game, clock, and floppy controller (360,1.2,720 or 1.4 -- any two) to replace
my original multi i/o card ($63). You need to use DOS 3.3.  In your config.
sys file, you will need to add a DRIVER.SYS statement (which will affect the
name of the drive (I ended up with my "B:" drive being called F:, since I
have 2 floppies, 1 partitioned hard drive (C:, D:) and my old ST225 (E;).
As luck would have it, using an ERSO bios on the motherboard, (and searching
with DEBUG through the bios on the high densisty supermulti i/o card, I
saw the same DTK copyright as was found on the motherboard bios), I only
needed to add a DRIVPARM=cntrl A etc  statement to let the system know that
the B: drive was a 1.44M. (I can't for the life of me remember what it was --
I am at a different computer now)  Read about DRIVPARM and DRIVER.SYS
as you'll be needing one or the other.  The catch about DRIVPARM is that
_and this is important_ only info I got about having the CNTL-A statement
right after the equals sign, came from a BBS response.  I've not found this
documented anywhere, and without it my drive won't work right.  Oh yes, one
other thing, depending on your drive, you may have to switch line 34 of the
1.44 drive.  I put in a slide switch.  One position is for all reading ,
writing to 720 and 1.44 disks, and formatting 720's. The other position is
only for formatting 1.44's.  Sceptics may not agree, but this is the only
was I can get it to work perfectly , and you don't argue with success.  The
drive is a Toshiba, the kind that comes with both gray and black faceplates,
and can be installed in 5.25 and 3.5 inch wide drive bays.
