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

1327 # Notes on the Comtrol Rocketport driver:
1329 # The exact values used for rp0 depend on how many boards you have
1330 # in the system. The manufacturer's sample configs are listed as:
1332 # Comtrol Rocketport ISA single card
1333 # device rp0 at isa? port 0x280
1335 # If instead you have two ISA cards, one installed at 0x100 and the
1336 # second installed at 0x180, then you should add the following to
1337 # your kernel configuration file:
1339 # device rp0 at isa? port 0x100
1340 # device rp1 at isa? port 0x180
1342 # For 4 ISA cards, it might be something like this:
