44# DEBUG happens to be magic.
45# The following is equivalent to 'config -g KERNELNAME' and creates
46# 'kernel.debug' compiled with -g debugging as well as a normal
47# 'kernel'. Use 'make install.debug' to install the debug kernel
48# but that isn't normally necessary as the debug symbols are not loaded
49# by the kernel and are not useful there anyway.

76# the limit. MAXSSIZ is the maximum that the stack limit can be
77# set to. You might want to set the default lower than the max,

589# SCSI DEVICES

591# SCSI DEVICE CONFIGURATION
592
593# The SCSI subsystem consists of the `base' SCSI code, a number of
594# high-level SCSI device `type' drivers, and the low-level host-adapter
595# device drivers. The host adapters are listed in the ISA and PCI
596# device configuration sections below.
597#
598# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
599# that a given bus, target, and LUN always come on line as the same
600# device unit. In earlier versions the unit numbers were assigned
601# in the order that the devices were probed on the SCSI bus. This
602# means that if you removed a disk drive, you may have had to rewrite
603# your /etc/fstab file, and also that you had to be careful when adding
604# a new disk as it may have been probed earlier and moved your device
605# configuration around.
606
607# This old behavior is maintained as the default behavior. The unit
608# assignment begins with the first non-wired down unit for a device
609# type. For example, if you wire a disk as "da3" then the first
610# non-wired disk will be assigned da4.
611
612# The syntax for wiring down devices is:
613
614# device scbus0 at ahc0 # Single bus device
615# device scbus1 at ahc1 bus 0 # Single bus device
616# device scbus3 at ahc2 bus 0 # Twin bus device
617# device scbus2 at ahc2 bus 1 # Twin bus device
618# device da0 at scbus0 target 0 unit 0
619# device da1 at scbus3 target 1
620# device da2 at scbus2 target 3
621# device sa1 at scbus1 target 6
622# device cd
623
624# "units" (SCSI logical unit number) that are not specified are
625# treated as if specified as LUN 0.
626
627# All SCSI devices allocate as many units as are required.
628
