INT 13 - Future Domain SCSI CONTROLLER - STOP SCSI DISK

	AH = 12h
	DL = hard drive ID
Return: CF set on error
	CF clear if successful
	AH = status code (see #00234 at AH=01h)
Notes:	available at least on the TMC-870 8-bit SCSI controller BIOS v6.0A
	if the given drive is a SCSI device, the SCSI Stop Unit command is sent
	  and either "Disk prepared for shipping" or "Disk Stop command failed"
	  is displayed
	the TMC-950 does not support any Future Domain BIOS calls; instead,
	  it provides a full CAM implementation (see INT 4F/AX=8100h)
