Add the following line to your CONFIG.SYS:
	device=driver.sys /D:x /H:1
                             ^replace with 0 for drive A, 1 for B
This will install a logical drive D: (or whatever the first unused
drive letter is) that is a single sided 3.5 drive.

I use this on my XT all the time. Do note that while you can format
disks for the ST on a PC and use them with no problems, the reverse
isn't true. Apparently the PC expects sector 1 to immediately follow
the index, and the ST doesn't care. <sigh>
