13  *
14  *  Changelog:
15  *   01-10-1997	RMK		Created, READONLY version
16  *   15-02-1998	RMK		READ/WRITE version
17  *				added DMA support and hardware definitions
18  *   14-03-1998	RMK		Updated DMA support
19  *				Added terminator control
20  *   15-04-1998	RMK		Only do PIO if FAS216 will allow it.
21  *   27-06-1998	RMK		Changed asm/delay.h to linux/delay.h
22  *   02-04-2000	RMK	0.0.3	Fixed NO_IRQ/NO_DMA problem, updated for new
23  *				error handling code.
