1 README file for the Linux g_NCR5380 driver.
4 NCR53c400 extensions (c) 1994,1995,1996 Kevin Lentin
6 This file documents the NCR53c400 extensions by Kevin Lentin and some
7 enhancements to the NCR5380 core.
9 This driver supports both NCR5380 and NCR53c400 cards in port or memory
10 mapped modes. Currently this driver can only support one of those mapping
11 modes at a time but it does support both of these chips at the same time.
12 The next release of this driver will support port & memory mapped cards at
13 the same time. It should be able to handle multiple different cards in the
16 The drivers/scsi/Makefile has an override in it for the most common
17 NCR53c400 card, the Trantor T130B in its default configuration:
21 The NCR53c400 does not support DMA but it does have Pseudo-DMA which is
22 supported by the driver.
24 This driver provides some information on what it has detected in
25 /proc/scsi/g_NCR5380/x where x is the scsi card number as detected at boot
26 time. More info to come in the future.
28 This driver works as a module.
29 When included as a module, parameters can be passed on the insmod/modprobe
31 irq=xx[,...] the interrupt(s)
32 base=xx[,...] the port or base address(es) (for port or memory mapped, resp.)
33 card=xx[,...] card type(s):
37 3 = Domex Technology Corp 3181E (DTC3181E)
38 4 = Hewlett Packard C2502
40 These old-style parameters can support only one card:
41 ncr_irq=xx the interrupt
42 ncr_addr=xx the port or base address (for port or memory
44 ncr_5380=1 to set up for a NCR5380 board
45 ncr_53c400=1 to set up for a NCR53C400 board
46 ncr_53c400a=1 to set up for a NCR53C400A board
47 dtc_3181e=1 to set up for a Domex Technology Corp 3181E board
48 hp_c2502=1 to set up for a Hewlett Packard C2502 board
51 OLD: modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_5380=1
52 NEW: modprobe g_NCR5380 irq=5 base=0x350 card=0
53 for a port mapped NCR5380 board or
55 OLD: modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1
56 NEW: modprobe g_NCR5380 irq=255 base=0xc8000 card=1
57 for a memory mapped NCR53C400 board with interrupts disabled or
59 NEW: modprobe g_NCR5380 irq=0,7 base=0x240,0x300 card=3,4
60 for two cards: DTC3181 (in non-PnP mode) at 0x240 with no IRQ
61 and HP C2502 at 0x300 with IRQ 7
63 (255 should be specified for no or DMA interrupt, 254 to autoprobe for an
64 IRQ line if overridden on the command line.)
