If it is "XT compatible", and runs MS-DOS 2.00 or above (hopefully ZENITH
then it can support a hard disk. "Hard Card" would be one
of the easier ways to do so.
If it can run DOS 3.20, or depending on WHICH MS-DOS 2.11 is available,
then the 360K drives can be trivially swapped out for 720K.
If you make a new boot disk (write protect the one that you have!)
if you delete everything except COMMAND.COM from the duplicate, then is
there room (about 300K!) for your driver? You will need to create
CONFIG.SYS and AUTOEXEC.BAT to run the driver. Surely, the authors of the
driver for a parallel port hard drive would not make a driver that would
not fit on a MINIMAL system disk! (although likely not fit on a
"complete" copy of DOS)
MicroSolutions "Backpack" drives always had a verion of their drivers that
would fit on a 360K, sometimes even on a 160K.
