	In general, any drive which works with a
	standard IBM XT or AT controller with a
	ST-506 interface ought to work fine. You
	can't reference more than 1024 tracks without
	the P5.1 upgrade, and you can't reference
	more than 8 heads without the WD2010. The
	chip doesn't require the upgrade, & the upgrade
	doesn't require the chip. It is possible to use
	RLL drives but you will only get 2/3 of the
	rated capacity, since the tracks will be
	formatted with only 17 512-byte sectors.

	It would be useful for people to post any
	known exceptions to this generality.
