688# SCSI DEVICES
689
690# SCSI DEVICE CONFIGURATION
691
692# The SCSI subsystem consists of the `base' SCSI code, a number of
693# high-level SCSI device `type' drivers, and the low-level host-adapter
694# device drivers. The host adapters are listed in the ISA and PCI
695# device configuration sections below.
696#
697# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
698# that a given bus, target, and LUN always come on line as the same
699# device unit. In earlier versions the unit numbers were assigned
700# in the order that the devices were probed on the SCSI bus. This
701# means that if you removed a disk drive, you may have had to rewrite
702# your /etc/fstab file, and also that you had to be careful when adding
703# a new disk as it may have been probed earlier and moved your device
704# configuration around.
705
706# This old behavior is maintained as the default behavior. The unit
707# assignment begins with the first non-wired down unit for a device
708# type. For example, if you wire a disk as "da3" then the first
709# non-wired disk will be assigned da4.
710
711# The syntax for wiring down devices is:
712
713# device scbus0 at ahc0 # Single bus device
714# device scbus1 at ahc1 bus 0 # Single bus device
715# device scbus3 at ahc2 bus 0 # Twin bus device
716# device scbus2 at ahc2 bus 1 # Twin bus device
717# device da0 at scbus0 target 0 unit 0
718# device da1 at scbus3 target 1
719# device da2 at scbus2 target 3
720# device sa1 at scbus1 target 6
721# device cd
722
723# "units" (SCSI logical unit number) that are not specified are
724# treated as if specified as LUN 0.
725
726# All SCSI devices allocate as many units as are required.

1476# the MPX 5030/5038, which is either a RealTek in disguise or a RealTek

1496# single port cards (single mode and multimode fiber) and the
1497# SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1498# The driver will autodetect the number of ports on the card and
1499# attach each one as a separate network interface.
1500#
1501# The 'ti' device provides support for PCI gigabit ethernet NICs based
1502# on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the

1505# this driver.
1506#
1507# The 'tl' device provides support for the Texas Instruments TNETE100
1508# series 'ThunderLAN' cards and integrated ethernet controllers. This
1509# includes several Compaq Netelligent 10/100 cards and the built-in
1510# ethernet controllers in several Compaq Prosignia, Proliant and

1520# based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1521# chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1522# Technologies PN102TX, and the AOpen/Acer ALN-320.
1523#
1524# The `vx' device provides support for the 3Com 3C590 and 3C595
1525# early support
1526#
1527# The `wb' device provides support for various fast ethernet adapters
1528# based on the Winbond W89C840F chip. Note: this is not the same as
1529# the Winbond W89C940F, which is an NE2000 clone.
