1) you must have a controller which will handle 4 drives.   This
	will have places for TWO cables, one for A/B and one
	for X/Y.
2) the controller should have an installable device driver which will
	recognize the extra drives.  What they will be named will
	be dependent on how your hard disk is set up.  If you
	use partitioning such as SpeedStore or OnTrak Disk Manager
	and therefore have a device driver for the hard disk,
	then if you load the driver for the floppies AFTER
	the hard disk, they will become the next drives after the
	last hard disk partition.  If however, you load the hard
	disk driver AFTER the floppy driver, you will get the 
	following:

	A/B	first two floppies
	C	first hard disk partition (recognized by BIOS)
	D/E	second floppies
	F...X	rest of the hard disk partitions


In general, drive letters are assigned in the order that the
devices init functions are executed by the BIOS for internal
floppy, internal hard disk, searching for ROM code between
A000:0 and F000;0 and executing each it finds, and finally
by DOS's init code executing in turn the init code for installable
found in CONFIG.SYS in order that they appear.
