1 README file for the Linux g_NCR5380 driver. 2 3 (c) 1993 Drew Eckhard 4 NCR53c400 extensions (c) 1994,1995,1996 Kevin Lentin 5 6 This file documents the NCR53c400 extensions by Kevin Lentin and some 7 enhancements to the NCR5380 core. 8 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 14 same machine. 15 16 The drivers/scsi/Makefile has an override in it for the most common 17 NCR53c400 card, the Trantor T130B in its default configuration: 18 Port: 0x350 19 IRQ : 5 20 21 The NCR53c400 does not support DMA but it does have Pseudo-DMA which is 22 supported by the driver. 23 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. 27 28 This driver works as a module. 29 When included as a module, parameters can be passed on the insmod/modprobe 30 command line: 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): 34 0 = NCR5380, 35 1 = NCR53C400, 36 2 = NCR53C400A, 37 3 = Domex Technology Corp 3181E (DTC3181E) 38 4 = Hewlett Packard C2502 39 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 43 mapped, resp.) 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 49 50 e.g. 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 54 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 58 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 62 63 (255 should be specified for no or DMA interrupt, 254 to autoprobe for an 64 IRQ line if overridden on the command line.) 65 66 67 Kevin Lentin 68 K.Lentin@cs.monash.edu.au
