690 # SCSI DEVICE CONFIGURATION
692 # The SCSI subsystem consists of the `base' SCSI code, a number of
693 # high-level SCSI device `type' drivers, and the low-level host-adapter
694 # device drivers. The host adapters are listed in the ISA and PCI
695 # device configuration sections below.
697 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
698 # that a given bus, target, and LUN always come on line as the same
699 # device unit. In earlier versions the unit numbers were assigned
700 # in the order that the devices were probed on the SCSI bus. This
701 # means that if you removed a disk drive, you may have had to rewrite
702 # your /etc/fstab file, and also that you had to be careful when adding
703 # a new disk as it may have been probed earlier and moved your device
704 # configuration around.
706 # This old behavior is maintained as the default behavior. The unit
707 # assignment begins with the first non-wired down unit for a device
708 # type. For example, if you wire a disk as "da3" then the first
709 # non-wired disk will be assigned da4.
711 # The syntax for wiring down devices is:
713 # device scbus0 at ahc0 # Single bus device
714 # device scbus1 at ahc1 bus 0 # Single bus device
715 # device scbus3 at ahc2 bus 0 # Twin bus device
716 # device scbus2 at ahc2 bus 1 # Twin bus device
717 # device da0 at scbus0 target 0 unit 0
718 # device da1 at scbus3 target 1
719 # device da2 at scbus2 target 3
720 # device sa1 at scbus1 target 6
723 # "units" (SCSI logical unit number) that are not specified are
724 # treated as if specified as LUN 0.
726 # All SCSI devices allocate as many units as are required.

1323 # Notes on the Comtrol Rocketport driver:
1325 # The exact values used for nrp0 depend on how many boards you have
1326 # in the system. The manufacturer's sample configs are listed as:
1328 # Comtrol Rocketport ISA single card
1329 # device nrp0 at isa? port 0x280
1331 # If instead you have two ISA cards, one installed at 0x100 and the
1332 # second installed at 0x180, then you should add the following to
1333 # your kernel configuration file:
1335 # device nrp0 at isa? port 0x100
1336 # device nrp1 at isa? port 0x180
1338 # For 4 ISA cards, it might be something like this:
1340 # device nrp0 at isa? port 0x180
1341 # device nrp1 at isa? port 0x100
1342 # device nrp2 at isa? port 0x340
1343 # device nrp3 at isa? port 0x240

1349 # Notes on the Specialix SI/XIO driver:
1350 # **This is NOT a Specialix supported Driver!**
1351 # The host card is memory, not IO mapped.
1352 # The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1353 # The Rev 2 host cards use a 32K chunk, on a 32K boundary.
