4 # Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers',
5 # 'makeoptions', 'hints' etc go into the kernel configuration that you
8 # Lines that begin with 'hints.' are NOT for config(8), they go into your
9 # hints file. See /boot/device.hints and/or the 'hints' config(8) directive.
11 # Please use ``make LINT'' to create an old-style LINT file if you want to
12 # do kernel test-builds.
18 # This directive is mandatory; it defines the architecture to be
19 # configured for; in this case, the 386 family based IBM-PC and
25 # This is the ``identification'' of the kernel. Usually this should
26 # be the same as the name of your kernel.
31 # The `maxusers' parameter controls the static sizing of a number of
32 # internal system tables by a complicated formula defined in param.c.
37 # We want LINT to cover profiling as well
41 # The `makeoptions' parameter allows variables to be passed to the
42 # generated Makefile in the build area.
44 # CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
45 # after most other flags. Here we use it to inhibit use of non-optimal
46 # gcc builtin functions (e.g., memcmp).
48 # DEBUG happens to be magic.
49 # The following is equivalent to 'config -g KERNELNAME' and creates
50 # 'kernel.debug' compiled with -g debugging as well as a normal
51 # 'kernel'. Use 'make install.debug' to install the debug kernel
52 # but that isn't normally necessary as the debug symbols are not loaded
53 # by the kernel and are not useful there anyway.

807 # SCSI DEVICE CONFIGURATION
809 # The SCSI subsystem consists of the `base' SCSI code, a number of
810 # high-level SCSI device `type' drivers, and the low-level host-adapter
811 # device drivers. The host adapters are listed in the ISA and PCI
812 # device configuration sections below.
814 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
815 # that a given bus, target, and LUN always come on line as the same
816 # device unit. In earlier versions the unit numbers were assigned
817 # in the order that the devices were probed on the SCSI bus. This
818 # means that if you removed a disk drive, you may have had to rewrite
819 # your /etc/fstab file, and also that you had to be careful when adding
820 # a new disk as it may have been probed earlier and moved your device
821 # configuration around.
823 # This old behavior is maintained as the default behavior. The unit
824 # assignment begins with the first non-wired down unit for a device
825 # type. For example, if you wire a disk as "da3" then the first
826 # non-wired disk will be assigned da4.
828 # The syntax for wiring down devices is:
830 hint.scbus.0.at="ahc0"
831 hint.scbus.1.at="ahc1"
833 hint.scbus.3.at="ahc2"

847 # "units" (SCSI logical unit number) that are not specified are
848 # treated as if specified as LUN 0.
850 # All SCSI devices allocate as many units as are required.
852 # The ch driver drives SCSI Media Changer ("jukebox") devices.
854 # The da driver drives SCSI Direct Access ("disk") and Optical Media
857 # The sa driver drives SCSI Sequential Access ("tape") devices.
859 # The cd driver drives SCSI Read Only Direct Access ("cd") devices.
861 # The ses driver drives SCSI Envinronment Services ("ses") and
862 # SAF-TE ("SCSI Accessable Fault-Tolerant Enclosure") devices.
864 # The pt driver drives SCSI Processor devices.
867 # Target Mode support is provided here but also requires that a SIM
868 # (SCSI Host Adapter Driver) provide support as well.
870 # The targ driver provides target mode support as a Processor type device.
871 # It exists to give the minimal context necessary to respond to Inquiry
872 # commands. There is a sample user application that shows how the rest
873 # of the command support might be done in /usr/share/examples/scsi_target.
