Future Domain SCSI BIOS - GET SCSI CONTROLLER INFORMATION

AH = 18h
DL = hard drive ID

Return:
CF set on error AH = status code (see #00234 at AH=01h) CF clear if successful AX = 4321h (magic number) CX = controller family code (see #00249) ---if family code=0200h DH = number of exclusively ROM-controlled SCSI devices DL = canonical SCSI device number for specified drive ---if family code <> 0200h BH = number of exclusively ROM-controlled SCSI devices BL = canonical SCSI device number for specified drive

Notes: 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. The TMC-950 does not support any Future Domain BIOS calls; instead, it provides a full CAM implementation (see INT 4F/AX=8100h)
