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

686# SCSI DEVICES
687
688# SCSI DEVICE CONFIGURATION
689
690# The SCSI subsystem consists of the `base' SCSI code, a number of
691# high-level SCSI device `type' drivers, and the low-level host-adapter
692# device drivers. The host adapters are listed in the ISA and PCI
693# device configuration sections below.
694#
695# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
696# that a given bus, target, and LUN always come on line as the same
697# device unit. In earlier versions the unit numbers were assigned
698# in the order that the devices were probed on the SCSI bus. This
699# means that if you removed a disk drive, you may have had to rewrite
700# your /etc/fstab file, and also that you had to be careful when adding
701# a new disk as it may have been probed earlier and moved your device
702# configuration around.
703
704# This old behavior is maintained as the default behavior. The unit
705# assignment begins with the first non-wired down unit for a device
706# type. For example, if you wire a disk as "da3" then the first
707# non-wired disk will be assigned da4.
708
709# The syntax for wiring down devices is:
710
711# device scbus0 at ahc0 # Single bus device
712# device scbus1 at ahc1 bus 0 # Single bus device
713# device scbus3 at ahc2 bus 0 # Twin bus device
714# device scbus2 at ahc2 bus 1 # Twin bus device
715# device da0 at scbus0 target 0 unit 0
716# device da1 at scbus3 target 1
717# device da2 at scbus2 target 3
718# device sa1 at scbus1 target 6
719# device cd
720
721# "units" (SCSI logical unit number) that are not specified are
722# treated as if specified as LUN 0.
723
724# All SCSI devices allocate as many units as are required.

1494# single port cards (single mode and multimode fiber) and the
1495# SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1496# The driver will autodetect the number of ports on the card and
1497# attach each one as a separate network interface.
1498#
1499# The 'ti' device provides support for PCI gigabit ethernet NICs based
1500# on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the

1506# series 'ThunderLAN' cards and integrated ethernet controllers. This

1508# ethernet controllers in several Compaq Prosignia, Proliant and

1518# based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1519# chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1520# Technologies PN102TX, and the AOpen/Acer ALN-320.

1526# based on the Winbond W89C840F chip. Note: this is not the same as
1527# the Winbond W89C940F, which is an NE2000 clone.
