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)
