Int 13/AH=1Bh

Future Domain SCSI CONTROLLER - GET POINTER TO SCSI DISK INFO BLOCK

AH = 1Bh
DL = hard drive ID

Return:
CF set on error
AH = status code (see #00234 at AH=01h)
CF clear if successful
ES:BX -> SCSI disk information block (see #00252)

Notes: Also sets a non-resettable flag which prevents some controller messages from being displayed. The TMC-950 does not support any Future Domain BIOS calls; instead, it provides a full CAM implementation (see INT 4F/AX=8100h)
