|
|
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=addr,irq
|
|
ncr53c400=addr,irq
|
|
ncr53c400a=addr,irq
|
|
dtc3181e=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.
|
|
|
|
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.
|
|
|
|
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_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
|
|
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.)
