I'd like to make a box with four floppy types:
5.25" 360 and 1.2, and
3.5" 720 and 1.44. I seem to recall someone here did this.
Sure. That was close to the "standard" configuration at my office.
My early (16K base) 5150 had 2 360s, a 5.25 720, a 3.5 720, and an 8" (on
a separate controller)
One of the XTs had 2 360s and a 720.
One of my ATs had a 360, a 1.2, and 2 1.4s
Another had a 360, a 1.2, a 1.4, a 2.8 (on parallel port), and a floptical
(SCSI).
ALL of the machines in that office had more than 2 floppies.
I think that Monte ended up with most of that hardware; I don't know
whether he would be able to locate it, or how much survived when the
school dumpstered his collection.
I imagine I can use the integrated floppy controller
and then add another
board to provide the additional controller.
I'll check the DOS manual to see if it says anything as Nico indicates.
DEVICE = DRIVER.SYS /D:physical-drive-number /F:drive-type (0=360,
1=1.2, 2=720, 7?=1.4)
If you are using an XT with 4 floppy support,
DRIVPARM can be used to override the configuration of a drive, but NOT
with the IBM BIOS!
