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.
