	THIS CODE IS OFFERED TO IKON'S CUSTOMERS AT NO CHARGE, WITH THE INTENT
	THAT IT BE USED WITH IKON'S BOARD LEVEL PRODUCTS.  WHILE IKON INTENDS
	TO KEEP THE DRIVER CURRENT WITH HP'S HARDWARE AND OPERATING SYSTEMS,
	AND TO KEEP THE CODE AS BUG FREE AS POSSIBLE, THIS IS NOT GUARANTEED.

	10 November, 1997	initial coding

				strategy uses a combination of p-i/o for leading &
				trailing bytes, and dma for long word blocks

				dma chaining is supported
