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
ncr5380=addr,irq
ncr53c400=addr,irq
ncr53c400a=addr,irq

The driver does not probe for any addresses or ports other than those in
the OVERRIDE or given to the kernel as above.

/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 parameters 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.
When included as a module, parameters can be passed on the insmod/modprobe
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
ncr_53c400a=1 to set up for a NCR53C400A board
dtc_3181e=1 to set up for a Domex Technology Corp 3181E board
hp_c2502=1 to set up for a Hewlett Packard C2502 board
e.g.
modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_5380=1
