879 # SCSI DEVICE CONFIGURATION
881 # The SCSI subsystem consists of the `base' SCSI code, a number of
882 # high-level SCSI device `type' drivers, and the low-level host-adapter
883 # device drivers. The host adapters are listed in the ISA and PCI
884 # device configuration sections below.
886 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
887 # that a given bus, target, and LUN always come on line as the same
888 # device unit. In earlier versions the unit numbers were assigned
889 # in the order that the devices were probed on the SCSI bus. This
890 # means that if you removed a disk drive, you may have had to rewrite
891 # your /etc/fstab file, and also that you had to be careful when adding
892 # a new disk as it may have been probed earlier and moved your device
893 # configuration around.
895 # This old behavior is maintained as the default behavior. The unit
896 # assignment begins with the first non-wired down unit for a device
897 # type. For example, if you wire a disk as "da3" then the first
898 # non-wired disk will be assigned da4.
900 # The syntax for wiring down devices is:
902 # device scbus0 at ahc0 # Single bus device
903 # device scbus1 at ahc1 bus 0 # Single bus device
904 # device scbus3 at ahc2 bus 0 # Twin bus device
905 # device scbus2 at ahc2 bus 1 # Twin bus device
906 # device da0 at scbus0 target 0 unit 0
907 # device da1 at scbus3 target 1
908 # device da2 at scbus2 target 3
909 # device sa1 at scbus1 target 6
912 # "units" (SCSI logical unit number) that are not specified are
913 # treated as if specified as LUN 0.
915 # All SCSI devices allocate as many units as are required.

1770 # SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1771 # The driver will autodetect the number of ports on the card and
1772 # attach each one as a separate network interface.
1774 # The 'ti' device provides support for PCI gigabit ethernet NICs based
1775 # on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
