+/* 
+ * TODO : flesh out DMA support, find some one actually using this (I have
+ * 	a memory mapped Trantor board that works fine)
+ */
+
+/*
+ * Options :
+ *
+ * PARITY - enable parity checking.  Not supported.
+ *
+ * SCSI2 - enable support for SCSI-II tagged queueing.  Untested.
+ *
+ * USLEEP - enable support for devices that don't disconnect.  Untested.
+ *
+ * The card is detected and initialized in one of several ways : 
+ * 1.  With command line overrides - NCR5380=port,irq may be 
+ *     used on the LILO command line to override the defaults.
+ *
+ * 2.  With the GENERIC_NCR5380_OVERRIDE compile time define.  This is 
+ *     specified as an array of address, irq, dma, board tuples.  Ie, for
+ *     one board at 0x350, IRQ5, no dma, I could say  
+ *     -DGENERIC_NCR5380_OVERRIDE={{0xcc000, 5, DMA_NONE, BOARD_NCR5380}}
+ * 
+ * -1 should be specified for no or DMA interrupt, -2 to autoprobe for an 
+ * 	IRQ line if overridden on the command line.
+ *
+ * 3.  When included as a module, with arguments passed on the command line:
+ *         ncr_irq=xx	the interrupt
+ *         ncr_addr=xx  the port or base address (for port or memory
+ *              	mapped, resp.)
+ *         ncr_dma=xx	the DMA
+ *         ncr_5380=1	to set up for a NCR5380 board
+ *         ncr_53c400=1	to set up for a NCR53C400 board
+ *     e.g.
+ *     modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_5380=1
+ *       for a port mapped NCR5380 board or
+ *     modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1
+ *       for a memory mapped NCR53C400 board with interrupts disabled.
+ * 
+ * 255 should be specified for no or DMA interrupt, 254 to autoprobe for an 
+ * 	IRQ line if overridden on the command line.
