INT 13 - Future Domain SCSI CONTROLLER - GET SCSI PARTIAL MEDIUM CAPACITY

	AH = 1Ah
	CH = track (bits 8,9 in high bits of CL)
	CL = sector (01h to number of sectors/track for drive)
	DH = head
	DL = hard drive ID
Return: CF set on error
	AH = status code (see #00234 at AH=01h)
	CX:DX = logical block number of last quickly-accessible block after
		given block
Notes:	sends SCSI Read Capacity command with the PMI bit set to obtain the
	  logical block address of the last block after which a substantial
	  delay in data transfer will be encountered (usually the last block
	  on the current cylinder).  No translation to 512 byte sectors is
	  performed on the result if data is stored on the disk in other than
	  512 byte sectors.
	the TMC-950 does not support any Future Domain BIOS calls; instead,
	  it provides a full CAM implementation (see INT 4F/AX=8100h)
