24 # be the same as the name of your kernel.
29 # The `maxusers' parameter controls the static sizing of a number of
30 # internal system tables by a formula defined in subr_param.c. Setting

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

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