AH = 18h
DL = hard drive ID
Return: CF set on error
AH = status code (see AH=01h)
CF clear if successful
AX = 4321h (magic number)
CX = controller family code
0203h TMC-1650/1660/1670/1680 (ROM 2.0)
BH = number of exclusively ROM-controlled SCSI devices
BL = canonical SCSI device number for specified drive
040Ah TMC-820/830/840/850/860/870/875/880/885 (ROM <= 6.0A)
BH = number of exclusively ROM-controlled SCSI devices
BL = canonical SCSI device number for specified drive
050Dh TMC-840/841/880/881 (ROM 5.2D)
BH = number of exclusively ROM-controlled SCSI devices
BL = canonical SCSI device number for specified drive
0700h TMC-830/850/860/875/885 (ROM 7.0)
DH = number of exclusively ROM-controlled SCSI devices
DL = canonical SCSI device number for specified drive
Note:   also sets an internal flag (non-resettable) which prevents some
controller messages from being displayed, allows writes to
removable devices (use caution!), and enables the INT 13 interface
for more than one drive (i.e. DL >= 81h) in at least some ROM
versions
