INT 0A - IRQ2 - Tandy 1000-series HARD DISK

Notes:	this interrupt may be masked by setting bit 2 on I/O port 21h
	the Tandy 1000, 1000A, and 1000HD use IRQ2 for the hard disk; the
	  1000EX, HX, RLX, RLX-HD, RLX-B, RLX-HD-B use IRQ5 instead; the
	  1000RL, RL-HD, SL, SL/2, TL, TL/2, and TL/3 are jumper-selectable
	  for either IRQ2 or IRQ5 (default IRQ5); the 1000SX and TX are
	  DIP-switch selectable for IRQ2 or IRQ5 (default IRQ2); the RSX and
	  RSX-HD use IRQ14.  Tandy systems which use IRQ2 for the hard disk
	  interrupt use IRQ5 for vertical retrace.
