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

744 # configuration and doesn't have to be explicitly configured.

1347 # If instead you have two ISA cards, one installed at 0x100 and the

1349 # your kernel configuration file:
1351 # device nrp0 at isa? port 0x100
1352 # device nrp1 at isa? port 0x180
1354 # For 4 ISA cards, it might be something like this:
