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

1789 # preferred driver for that chip.
1791 # The 'rl' device provides support for PCI fast ethernet adapters based
1792 # on the RealTek 8129/8139 chipset. Note that the RealTek driver defaults
1793 # to using programmed I/O to do register accesses because memory mapped
1794 # mode seems to cause severe lockups on SMP hardware. This driver also
1795 # supports the Accton EN1207D `Cheetah' adapter, which uses a chip called
1796 # the MPX 5030/5038, which is either a RealTek in disguise or a RealTek
1797 # workalike. Note that the D-Link DFE-530TX+ uses the RealTek chipset
1798 # and is supported by this driver, not the 'vr' driver.
1800 # The 'sf' device provides support for Adaptec Duralink PCI fast
1801 # ethernet adapters based on the Adaptec AIC-6915 "starfire" controller.
1802 # This includes dual and quad port cards, as well as one 100baseFX card.
1803 # Most of these are 64-bit PCI devices, except for one single port
1804 # card which is 32-bit.
1806 # The 'ste' device provides support for adapters based on the Sundance
1807 # Technologies ST201 PCI fast ethernet controller. This includes the
1810 # The 'sis' device provides support for adapters based on the Silicon
1811 # Integrated Systems SiS 900 and SiS 7016 PCI fast ethernet controller
1814 # The 'sk' device provides support for the SysKonnect SK-984x series
1815 # PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1816 # single port cards (single mode and multimode fiber) and the
1817 # SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1818 # The driver will autodetect the number of ports on the card and
1819 # attach each one as a separate network interface.
1821 # The 'ti' device provides support for PCI gigabit ethernet NICs based
1822 # on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1823 # Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.
1824 # Note that you will probably want to bump up NMBCLUSTERS a lot to use
1827 # The 'tl' device provides support for the Texas Instruments TNETE100
1828 # series 'ThunderLAN' cards and integrated ethernet controllers. This
1829 # includes several Compaq Netelligent 10/100 cards and the built-in
1830 # ethernet controllers in several Compaq Prosignia, Proliant and
1831 # Deskpro systems. It also supports several Olicom 10Mbps and 10/100

1840 # based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1841 # chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking

1844 # The `vx' device provides support for the 3Com 3C590 and 3C595
1847 # The `wb' device provides support for various fast ethernet adapters
1848 # based on the Winbond W89C840F chip. Note: this is not the same as
1849 # the Winbond W89C940F, which is an NE2000 clone.
1851 # The `xl' device provides support for the 3Com 3c900, 3c905 and
1852 # 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1853 # includes the integrated 3c905B-TX chips in certain Dell Optiplex and
1854 # Dell Precision desktop machines and the integrated 3c905-TX chips
1855 # in Dell Latitude laptop docking stations.

1869 # bt848/bt848a/bt849a/bt878/bt879 chipset. When used with a TV Tuner it forms a
