872
873# SCSI DEVICE CONFIGURATION
874
875# The SCSI subsystem consists of the `base' SCSI code, a number of
876# high-level SCSI device `type' drivers, and the low-level host-adapter
877# device drivers. The host adapters are listed in the ISA and PCI
878# device configuration sections below.
879#
880# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
881# that a given bus, target, and LUN always come on line as the same
882# device unit. In earlier versions the unit numbers were assigned
883# in the order that the devices were probed on the SCSI bus. This
884# means that if you removed a disk drive, you may have had to rewrite
885# your /etc/fstab file, and also that you had to be careful when adding
886# a new disk as it may have been probed earlier and moved your device
887# configuration around.
888
889# This old behavior is maintained as the default behavior. The unit
890# assignment begins with the first non-wired down unit for a device
891# type. For example, if you wire a disk as "da3" then the first
892# non-wired disk will be assigned da4.
893
894# The syntax for wiring down devices is:
895
896# device scbus0 at ahc0 # Single bus device
897# device scbus1 at ahc1 bus 0 # Single bus device
898# device scbus3 at ahc2 bus 0 # Twin bus device
899# device scbus2 at ahc2 bus 1 # Twin bus device
900# device da0 at scbus0 target 0 unit 0
901# device da1 at scbus3 target 1
902# device da2 at scbus2 target 3
903# device sa1 at scbus1 target 6
904# device cd
905
906# "units" (SCSI logical unit number) that are not specified are
907# treated as if specified as LUN 0.

909# All SCSI devices allocate as many units as are required.

1807# PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1808# single port cards (single mode and multimode fiber) and the
1809# SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1810# The driver will autodetect the number of ports on the card and
1811# attach each one as a separate network interface.
1812#
1813# The 'ti' device provides support for PCI gigabit ethernet NICs based
1814# on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1815# Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.
1816# Note that you will probably want to bump up NMBCLUSTERS a lot to use
1817# this driver.
1818#
1819# The 'tl' device provides support for the Texas Instruments TNETE100
1820# series 'ThunderLAN' cards and integrated ethernet controllers. This
1821# includes several Compaq Netelligent 10/100 cards and the built-in
1822# ethernet controllers in several Compaq Prosignia, Proliant and
1823# Deskpro systems. It also supports several Olicom 10Mbps and 10/100
1824# boards.

1829# 10/100 adapters.
1830#
1831# The `vr' device provides support for various fast ethernet adapters
1832# based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1833# chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1834# Technologies PN102TX, and the AOpen/Acer ALN-320.
1835#
1836# The `vx' device provides support for the 3Com 3C590 and 3C595
1837# early support
1838#
1839# The `wb' device provides support for various fast ethernet adapters
1840# based on the Winbond W89C840F chip. Note: this is not the same as
1841# the Winbond W89C940F, which is an NE2000 clone.
