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

1744 # PCnet/PRO and PCnet/Home. These were previously handled by the lnc
1745 # driver (and still will be if you leave this driver out of the kernel).
1747 # Te 're' device provides support for PCI GigaBit ethernet adapters based
1748 # on the RealTek 8169 chipset. It also supports the 8139C+ and is the
1749 # prefered driver for that chip.
1751 # The 'rl' device provides support for PCI fast ethernet adapters based
1752 # on the RealTek 8129/8139 chipset. Note that the RealTek driver defaults
1753 # to using programmed I/O to do register accesses because memory mapped
1754 # mode seems to cause severe lockups on SMP hardware. This driver also
1755 # supports the Accton EN1207D `Cheetah' adapter, which uses a chip called
1756 # the MPX 5030/5038, which is either a RealTek in disguise or a RealTek
1757 # workalike. Note that the D-Link DFE-530TX+ uses the RealTek chipset
1758 # and is supported by this driver, not the 'vr' driver.
1760 # The 'sf' device provides support for Adaptec Duralink PCI fast
1761 # ethernet adapters based on the Adaptec AIC-6915 "starfire" controller.
1762 # This includes dual and quad port cards, as well as one 100baseFX card.

1764 # card which is 32-bit.

1767 # Technologies ST201 PCI fast ethernet controller. This includes the

1774 # The 'sk' device provides support for the SysKonnect SK-984x series
1775 # PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1776 # single port cards (single mode and multimode fiber) and the
1777 # SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1778 # The driver will autodetect the number of ports on the card and
1779 # attach each one as a separate network interface.
1781 # The 'ti' device provides support for PCI gigabit ethernet NICs based
1782 # on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1783 # Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.
1784 # Note that you will probably want to bump up NMBCLUSTERS a lot to use
1787 # The 'tl' device provides support for the Texas Instruments TNETE100
1788 # series 'ThunderLAN' cards and integrated ethernet controllers. This
1789 # includes several Compaq Netelligent 10/100 cards and the built-in
1790 # ethernet controllers in several Compaq Prosignia, Proliant and

1800 # based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1801 # chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking

1807 # The `wb' device provides support for various fast ethernet adapters
1808 # based on the Winbond W89C840F chip. Note: this is not the same as
1809 # the Winbond W89C940F, which is an NE2000 clone.
1811 # The `xl' device provides support for the 3Com 3c900, 3c905 and
1812 # 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1813 # includes the integrated 3c905B-TX chips in certain Dell Optiplex and

1815 # in Dell Latitude laptop docking stations.
