13# This directive is mandatory; it defines the architecture to be
14# configured for; in this case, the 386 family.  You must also specify
15# at least one CPU (the one you intend to run on); deleting the

263# SCSI DEVICES
264
265# SCSI DEVICE CONFIGURATION
266
267# The SCSI subsystem consists of the `base' SCSI code, a number of
268# high-level SCSI device `type' drivers, and the low-level host-adapter
269# device drivers.  The host adapters are listed in the ISA and PCI
270# device configuration sections below.
271#
272# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
273# that a given bus, target, and LUN always come on line as the same
274# device unit.  In earlier versions the unit numbers were assigned
275# in the order that the devices were probed on the SCSI bus.  This
276# means that if you removed a disk drive, you may have had to rewrite
277# your /etc/fstab file, and also that you had to be careful when adding
278# a new disk as it may have been probed earlier and moved your device
279# configuration around.
280
281# This old behavior is maintained as the default behavior.  The unit
282# assignment begins with the first non-wired down unit for a device
283# type.  For example, if you wire a disk as "sd3" then the first
284# non-wired disk will be assigned sd4.
285
286# The syntax for wiring down devices is:
287
288# controller	scbus0 at ahc0		# Single bus device
289# controller	scbus1 at ahc1 bus 0	# Single bus device
290# controller	scbus3 at ahc2 bus 0	# Twin bus device
