203# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
204# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
205# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
206#
207# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).

215# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
216# flush at hold state.
217#
218# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
219# without cache flush at hold state, and (2) write-back CPU cache on
220# Cyrix 6x86 whose revision < 2.7 (NOTE 2).

222# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
223# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is

849# SCSI DEVICES
850
851# SCSI DEVICE CONFIGURATION
852
853# The SCSI subsystem consists of the `base' SCSI code, a number of
854# high-level SCSI device `type' drivers, and the low-level host-adapter
855# device drivers. The host adapters are listed in the ISA and PCI
856# device configuration sections below.
857#
858# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
859# that a given bus, target, and LUN always come on line as the same
860# device unit. In earlier versions the unit numbers were assigned
861# in the order that the devices were probed on the SCSI bus. This
862# means that if you removed a disk drive, you may have had to rewrite
863# your /etc/fstab file, and also that you had to be careful when adding
864# a new disk as it may have been probed earlier and moved your device
865# configuration around.
866
867# This old behavior is maintained as the default behavior. The unit
868# assignment begins with the first non-wired down unit for a device
869# type. For example, if you wire a disk as "da3" then the first
870# non-wired disk will be assigned da4.
871
872# The syntax for wiring down devices is:
873
874# device scbus0 at ahc0 # Single bus device
875# device scbus1 at ahc1 bus 0 # Single bus device
876# device scbus3 at ahc2 bus 0 # Twin bus device
877# device scbus2 at ahc2 bus 1 # Twin bus device
878# device da0 at scbus0 target 0 unit 0
879# device da1 at scbus3 target 1
880# device da2 at scbus2 target 3
881# device sa1 at scbus1 target 6
882# device cd
883
884# "units" (SCSI logical unit number) that are not specified are
885# treated as if specified as LUN 0.
886
887# All SCSI devices allocate as many units as are required.
888
