27 # The `maxusers' parameter controls the static sizing of a number of
28 # internal system tables by a formula defined in subr_param.c. Setting
29 # maxusers to 0 will cause the system to auto-size based on physical
35 # The `makeoptions' parameter allows variables to be passed to the
36 # generated Makefile in the build area.

39 # after most other flags. Here we use it to inhibit use of non-optimal
40 # gcc builtin functions (e.g., memcmp).
42 # DEBUG happens to be magic.
43 # The following is equivalent to 'config -g KERNELNAME' and creates
44 # 'kernel.debug' compiled with -g debugging as well as a normal

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

1791 # driver (and still will be if you leave this driver out of the kernel).
1793 # Te 're' device provides support for PCI GigaBit ethernet adapters based
1794 # on the RealTek 8169 chipset. It also supports the 8139C+ and is the
1795 # preferred driver for that chip.
1797 # The 'rl' device provides support for PCI fast ethernet adapters based
1798 # on the RealTek 8129/8139 chipset. Note that the RealTek driver defaults
1799 # to using programmed I/O to do register accesses because memory mapped
1800 # mode seems to cause severe lockups on SMP hardware. This driver also
1801 # supports the Accton EN1207D `Cheetah' adapter, which uses a chip called
1802 # the MPX 5030/5038, which is either a RealTek in disguise or a RealTek

1807 # ethernet adapters based on the Adaptec AIC-6915 "starfire" controller.
1808 # This includes dual and quad port cards, as well as one 100baseFX card.

1820 # The 'sk' device provides support for the SysKonnect SK-984x series
1821 # PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1822 # single port cards (single mode and multimode fiber) and the
1823 # SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1824 # The driver will autodetect the number of ports on the card and
1825 # attach each one as a separate network interface.
1827 # The 'ti' device provides support for PCI gigabit ethernet NICs based
1828 # on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1829 # Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.
1830 # Note that you will probably want to bump up NMBCLUSTERS a lot to use
1833 # The 'tl' device provides support for the Texas Instruments TNETE100
1834 # series 'ThunderLAN' cards and integrated ethernet controllers. This
1835 # includes several Compaq Netelligent 10/100 cards and the built-in
1836 # ethernet controllers in several Compaq Prosignia, Proliant and
1837 # Deskpro systems. It also supports several Olicom 10Mbps and 10/100
1840 # The `tx' device provides support for the SMC 9432 TX, BTX and FTX cards.
1842 # The `txp' device provides support for the 3Com 3cR990 "Typhoon"

1846 # based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1847 # chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1848 # Technologies PN102TX, and the AOpen/Acer ALN-320.
1850 # The `vx' device provides support for the 3Com 3C590 and 3C595
1853 # The `wb' device provides support for various fast ethernet adapters
1854 # based on the Winbond W89C840F chip. Note: this is not the same as
1855 # the Winbond W89C940F, which is an NE2000 clone.
1857 # The `xl' device provides support for the 3Com 3c900, 3c905 and
1858 # 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1859 # includes the integrated 3c905B-TX chips in certain Dell Optiplex and
1860 # Dell Precision desktop machines and the integrated 3c905-TX chips
1861 # in Dell Latitude laptop docking stations.
1863 # The `fpa' device provides support for the Digital DEFPA PCI FDDI
1864 # adapter. pseudo-device fddi is also needed.

1877 # The 'bktr' device is a PCI video capture device using the Brooktree
1878 # bt848/bt848a/bt849a/bt878/bt879 chipset. When used with a TV Tuner it forms a
