37 # The `makeoptions' parameter allows variables to be passed to the

44 # DEBUG happens to be magic.

832 # SCSI DEVICE CONFIGURATION
834 # The SCSI subsystem consists of the `base' SCSI code, a number of
835 # high-level SCSI device `type' drivers, and the low-level host-adapter
836 # device drivers. The host adapters are listed in the ISA and PCI
837 # device configuration sections below.
839 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
840 # that a given bus, target, and LUN always come on line as the same
841 # device unit. In earlier versions the unit numbers were assigned
842 # in the order that the devices were probed on the SCSI bus. This
843 # means that if you removed a disk drive, you may have had to rewrite
844 # your /etc/fstab file, and also that you had to be careful when adding
845 # a new disk as it may have been probed earlier and moved your device
846 # configuration around.
848 # This old behavior is maintained as the default behavior. The unit
849 # assignment begins with the first non-wired down unit for a device
850 # type. For example, if you wire a disk as "da3" then the first
851 # non-wired disk will be assigned da4.
853 # The syntax for wiring down devices is:
855 # device scbus0 at ahc0 # Single bus device
856 # device scbus1 at ahc1 bus 0 # Single bus device
857 # device scbus3 at ahc2 bus 0 # Twin bus device
858 # device scbus2 at ahc2 bus 1 # Twin bus device
859 # device da0 at scbus0 target 0 unit 0
860 # device da1 at scbus3 target 1
861 # device da2 at scbus2 target 3
862 # device sa1 at scbus1 target 6
865 # "units" (SCSI logical unit number) that are not specified are
866 # treated as if specified as LUN 0.
868 # All SCSI devices allocate as many units as are required.
