+REAME file for the Linux g_NCR5380 driver.
+
+(c) 1993 Drew Eckhard
+NCR53c400 extensions (c) 1994,1995,1996 Kevin Lentin
+
+This file documents the NCR53c400 extensions by Kevin Lentin and some
+enhancements to the NCR5380 core.
+
+This driver supports both NCR5380 and NCR53c400 cards in port or memory
+mapped modes. Currently this driver can only support one of those mapping
+modes at a time but it does support both of these chips at the same time.
+The next release of this driver will support port & memory mapped cards at
+the same time. It should be able to handle multiple different cards in the
+same machine.
+
+The drivers/scsi/Makefile has an override in it for the most common
+NCR53c400 card, the Trantor T130B in its default configuration:
+	Port: 0x350
+	IRQ : 5
+
+The NCR53c400 does not support DMA but it does have Pseudo-DMA which is
+supported by the driver.
+
+If the default configuration does not work for you, you can use the kernel
+command lines (eg using the lilo append command):
+	ncr5380=port,irq,dma
+	ncr53c400=port,irq
+or
+	ncr5380=base,irq,dma
+	ncr53c400=base,irq
+
+The driver does not probe for any addresses or ports other than those in
+the OVERRIDE or given to the kernel as above.
+
+This driver provides some information on what it has detected in
+/proc/scsi/g_NCR5380/x where x is the scsi card number as detected at boot
+time. More info to come in the future.
+
+When NCR53c400 support is compiled in, BIOS paramaters will be returned by
+the driver (the raw 5380 driver does not and I don't plan to fiddle with
+it!).
+
+This driver works as a module.
