README file for the Linux g_NCR5380 driver.

|
||||
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 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
|
||||
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.)
