	AH = 18h
	DL = drive number
	CH = lower 8 bits of highest cylinder number (number of cylinders - 1)
	CL = sectors per track (bits 0-5)
	     top 2 bits of highest cylinder number (bits 6,7)
Return: AH = status
	    00h requested combination supported
	    01h function not available
	    0Ch not supported or drive type unknown
	    80h there is no disk in the drive
	ES:DI -> 11-byte parameter table (see #01264 at INT 1E)
