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

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

1338 # If instead you have two ISA cards, one installed at 0x100 and the

1342 # device rp0 at isa? port 0x100
1343 # device rp1 at isa? port 0x180
