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 AH=01h)
CX:DX = logical block number of last quickly-accessible block after
given block
Note:   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.
