	BYTE OFFSET	VALUE	COMMENTS
13	(Note 9)	Cylinder skew factor (LSB)
14		(Note 10)	Drive type field

16		(Note 11)	Reserved

NOTES:	1.	Tracks per zone is set to $0001 if bit 11 (track = zone flag) of
		the attach packets attribute word (byte offset $10) is = 0.
		Tracks per zone is set to the number of heads (attach packet
		byte offset $07) if bit 11 (track = zone flag) of the attach
		packets attribute word (byte offset $10) is = 1.
	2.	Alternate sectors per zone is taken from the attach packets
		alternate sectors per zone field (byte offset $1E for "old"
		attach ($08), or offset $28 for "new" ATTACH ($78)).
	3.	Alternate tracks per zone field is left as the default value as
		returned from the mode sense command.
