44# DEBUG happens to be magic.
45# The following is equivalent to 'config -g KERNELNAME' and creates

703# SCSI DEVICES
704
705# SCSI DEVICE CONFIGURATION
706
707# The SCSI subsystem consists of the `base' SCSI code, a number of
708# high-level SCSI device `type' drivers, and the low-level host-adapter
709# device drivers. The host adapters are listed in the ISA and PCI
710# device configuration sections below.
711#
712# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
713# that a given bus, target, and LUN always come on line as the same
714# device unit. In earlier versions the unit numbers were assigned
715# in the order that the devices were probed on the SCSI bus. This
716# means that if you removed a disk drive, you may have had to rewrite
717# your /etc/fstab file, and also that you had to be careful when adding
718# a new disk as it may have been probed earlier and moved your device
719# configuration around.
720
721# This old behavior is maintained as the default behavior. The unit
722# assignment begins with the first non-wired down unit for a device
723# type. For example, if you wire a disk as "da3" then the first
724# non-wired disk will be assigned da4.
725
726# The syntax for wiring down devices is:
727
728# device scbus0 at ahc0 # Single bus device
729# device scbus1 at ahc1 bus 0 # Single bus device
730# device scbus3 at ahc2 bus 0 # Twin bus device
731# device scbus2 at ahc2 bus 1 # Twin bus device
732# device da0 at scbus0 target 0 unit 0
733# device da1 at scbus3 target 1
734# device da2 at scbus2 target 3
735# device sa1 at scbus1 target 6
736# device cd
737
738# "units" (SCSI logical unit number) that are not specified are
739# treated as if specified as LUN 0.

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

1478# The 'rl' device provides support for PCI fast ethernet adapters based
1479# on the RealTek 8129/8139 chipset. Note that the RealTek driver defaults
1480# to using programmed I/O to do register accesses because memory mapped
1481# mode seems to cause severe lockups on SMP hardware. This driver also
1482# supports the Accton EN1207D `Cheetah' adapter, which uses a chip called
1483# the MPX 5030/5038, which is either a RealTek in disguise or a RealTek
1484# workalike. Note that the D-Link DFE-530TX+ uses the RealTek chipset
1485# and is supported by this driver, not the 'vr' driver.
1486#
1487# The 'sf' device provides support for Adaptec Duralink PCI fast
1488# ethernet adapters based on the Adaptec AIC-6915 "starfire" controller.
1489# This includes dual and quad port cards, as well as one 100baseFX card.
1490# Most of these are 64-bit PCI devices, except for one single port
1491# card which is 32-bit.
1492#
1493# The 'ste' device provides support for adapters based on the Sundance
1494# Technologies ST201 PCI fast ethernet controller. This includes the
1495# D-Link DFE-550TX.
1496#
1497# The 'sis' device provides support for adapters based on the Silicon
1498# Integrated Systems SiS 900 and SiS 7016 PCI fast ethernet controller
1499# chips.
1500#
1501# The 'sk' device provides support for the SysKonnect SK-984x series
1502# PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1503# single port cards (single mode and multimode fiber) and the
1504# SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1505# The driver will autodetect the number of ports on the card and
1506# attach each one as a separate network interface.
1507#
1508# The 'ti' device provides support for PCI gigabit ethernet NICs based
1509# on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1510# Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.
1511# Note that you will probably want to bump up NMBCLUSTERS a lot to use
1512# this driver.
1513#
1514# The 'tl' device provides support for the Texas Instruments TNETE100
1515# series 'ThunderLAN' cards and integrated ethernet controllers. This
1516# includes several Compaq Netelligent 10/100 cards and the built-in
1517# ethernet controllers in several Compaq Prosignia, Proliant and
1518# Deskpro systems. It also supports several Olicom 10Mbps and 10/100
1519# boards.
1520#
1521# The `tx' device provides support for the SMC 9432 TX, BTX and FTX cards.

1524# 10/100 adapters.
1525#
1526# The `vr' device provides support for various fast ethernet adapters
1527# based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1528# chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1529# Technologies PN102TX, and the AOpen/Acer ALN-320.
1530#
1531# The `vx' device provides support for the 3Com 3C590 and 3C595
1532# early support
1533#
1534# The `wb' device provides support for various fast ethernet adapters
1535# based on the Winbond W89C840F chip. Note: this is not the same as
1536# the Winbond W89C940F, which is an NE2000 clone.
1537#
1538# The `xl' device provides support for the 3Com 3c900, 3c905 and
1539# 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1540# includes the integrated 3c905B-TX chips in certain Dell Optiplex and
1541# Dell Precision desktop machines and the integrated 3c905-TX chips
1542# in Dell Latitude laptop docking stations.
1543#
1544# The 'bktr' device is a PCI video capture device using the Brooktree
1545# bt848/bt848a/bt849a/bt878/bt879 chipset. When used with a TV Tuner it forms a
