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

1801 # includes the SMC EZ Card 1000 (SMC9462TX), D-Link DGE-500T, Asante
1802 # FriendlyNet GigaNIX 1000TA and 1000TPC, the Addtron AEG320T, the
1803 # LinkSys EG1032 and EG1064, the Surecom EP-320G-TX and the Netgear GA622T.
1805 # The 'pcn' device provides support for PCI fast ethernet adapters based
1806 # on the AMD Am79c97x chipsets, including the PCnet/FAST, PCnet/FAST+,
1807 # PCnet/PRO and PCnet/Home. These were previously handled by the lnc
1808 # driver (and still will be if you leave this driver out of the kernel).
1810 # Te 're' device provides support for PCI GigaBit ethernet adapters based
1811 # on the RealTek 8169 chipset. It also supports the 8139C+ and is the
1812 # preferred driver for that chip.
1814 # The 'rl' device provides support for PCI fast ethernet adapters based
1815 # on the RealTek 8129/8139 chipset. Note that the RealTek driver defaults
1816 # to using programmed I/O to do register accesses because memory mapped
1817 # mode seems to cause severe lockups on SMP hardware. This driver also
1818 # supports the Accton EN1207D `Cheetah' adapter, which uses a chip called
1819 # the MPX 5030/5038, which is either a RealTek in disguise or a RealTek
1820 # workalike. Note that the D-Link DFE-530TX+ uses the RealTek chipset
1821 # and is supported by this driver, not the 'vr' driver.
1823 # The 'sf' device provides support for Adaptec Duralink PCI fast
1824 # ethernet adapters based on the Adaptec AIC-6915 "starfire" controller.
1825 # This includes dual and quad port cards, as well as one 100baseFX card.
1826 # Most of these are 64-bit PCI devices, except for one single port
1827 # card which is 32-bit.
1829 # The 'ste' device provides support for adapters based on the Sundance
1830 # Technologies ST201 PCI fast ethernet controller. This includes the
1833 # The 'sis' device provides support for adapters based on the Silicon
1834 # Integrated Systems SiS 900 and SiS 7016 PCI fast ethernet controller
1837 # The 'sk' device provides support for the SysKonnect SK-984x series
1838 # PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1839 # single port cards (single mode and multimode fiber) and the
1840 # SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1841 # The driver will autodetect the number of ports on the card and
1842 # attach each one as a separate network interface.
1844 # The 'ti' device provides support for PCI gigabit ethernet NICs based
1845 # on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1846 # Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.
1847 # Note that you will probably want to bump up NMBCLUSTERS a lot to use
1850 # The 'tl' device provides support for the Texas Instruments TNETE100
1851 # series 'ThunderLAN' cards and integrated ethernet controllers. This
1852 # includes several Compaq Netelligent 10/100 cards and the built-in
1853 # ethernet controllers in several Compaq Prosignia, Proliant and
1854 # Deskpro systems. It also supports several Olicom 10Mbps and 10/100
1857 # The `tx' device provides support for the SMC 9432 TX, BTX and FTX cards.
1859 # The `txp' device provides support for the 3Com 3cR990 "Typhoon"
1862 # The `vr' device provides support for various fast ethernet adapters
1863 # based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1864 # chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1865 # Technologies PN102TX, and the AOpen/Acer ALN-320.
1867 # The `vx' device provides support for the 3Com 3C590 and 3C595
1870 # The `wb' device provides support for various fast ethernet adapters
1871 # based on the Winbond W89C840F chip. Note: this is not the same as
1872 # the Winbond W89C940F, which is an NE2000 clone.
1874 # The `xl' device provides support for the 3Com 3c900, 3c905 and
1875 # 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1876 # includes the integrated 3c905B-TX chips in certain Dell Optiplex and
1877 # Dell Precision desktop machines and the integrated 3c905-TX chips
1878 # in Dell Latitude laptop docking stations.
1880 # The `meteor' device is a PCI video capture board. It can also have the
1881 # following options:
1882 # options METEOR_ALLOC_PAGES=xxx preallocate kernel pages for data entry
1883 # figure (ROWS*COLUMN*BYTES_PER_PIXEL*FRAME+PAGE_SIZE-1)/PAGE_SIZE

1891 # The 'bktr' device is a PCI video capture device using the Brooktree
1892 # bt848/bt848a/bt849a/bt878/bt879 chipset. When used with a TV Tuner it forms a
