INT 13 - 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 AH=01h)
        CF clear if successful
            ES:BX -> SCSI disk information block
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)
SeeAlso: AH=18h"SCSI",AH=1Ch"SCSI"

Format of SCSI disk information block:
Offset  Size    Description
 00h    BYTE    drive physical information (see below)
 01h    WORD    translated number of cylinders
 03h    BYTE    translated number of heads
 04h    BYTE    translated number of sectors per track (17, 34, or 63)
 05h    BYTE    drive address
                bits 0-2: logical unit number
                bits 3-5: device number
 06h    BYTE    01h at initialization
 07h    BYTE    sense code byte 00h, or extended sense code byte 0Ch
 08h    BYTE    00h
 09h    BYTE    00h or extended sense code byte 02h (sense key)
 0Ah    BYTE    00h
 0Bh 10 BYTEs   copy of Command Descriptor Block (CDB)
 15h    DWORD   translated number of sectors on device

Bitfields for device physical information:
 bit 0  ???
 bit 1  device uses parity
 bit 2  256 bytes per sector instead of 512
 bit 3  don't have capacity yet???
 bit 4  disk is removable
 bit 5  logical unit number is not present
