-README file for the Linux g_NCR5380 driver.
-

-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 NCR5380 and NCR53c400 and compatible cards in port or
-memory mapped modes.
-
-Use of an interrupt is recommended, if supported by the board, as this will
-allow targets to disconnect and thereby improve SCSI bus utilization.
-
-If the irq parameter is 254 or is omitted entirely, the driver will probe
-for the correct IRQ line automatically. If the irq parameter is 0 or 255
-then no IRQ will be used.
-
-The NCR53c400 does not support DMA but it does have Pseudo-DMA which is
-supported by the driver.
-
-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:
- irq=xx[,...] the interrupt(s)
- base=xx[,...] the port or base address(es) (for port or memory mapped, resp.)
- card=xx[,...] card type(s):
- 0 = NCR5380,
- 1 = NCR53C400,
- 2 = NCR53C400A,
- 3 = Domex Technology Corp 3181E (DTC3181E)
- 4 = Hewlett Packard C2502
-
-These old-style parameters can support only one card:
- 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. Trantor T130B in its default configuration:
-modprobe g_NCR5380 irq=5 base=0x350 card=1
-or alternatively, using the old syntax,
-modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_53c400=1
-
-E.g. a port mapped NCR5380 board, driver to probe for IRQ:
-modprobe g_NCR5380 base=0x350 card=0
-or alternatively,
-modprobe g_NCR5380 ncr_addr=0x350 ncr_5380=1
-
-E.g. a memory mapped NCR53C400 board with no IRQ:
-modprobe g_NCR5380 irq=255 base=0xc8000 card=1
-or alternatively,
-modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1
-
-E.g. two cards, DTC3181 (in non-PnP mode) at 0x240 with no IRQ
-and HP C2502 at 0x300 with IRQ 7:
-modprobe g_NCR5380 irq=0,7 base=0x240,0x300 card=3,4
