200# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
201# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
202#
203# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).

205# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
206# enters suspend mode following execution of HALT instruction.

212# flush at hold state.

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

218# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
219# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
220# executed. This option is only needed if I586_CPU is also defined,

843# SCSI DEVICES
844
845# SCSI DEVICE CONFIGURATION
846
847# The SCSI subsystem consists of the `base' SCSI code, a number of
848# high-level SCSI device `type' drivers, and the low-level host-adapter
849# device drivers. The host adapters are listed in the ISA and PCI
850# device configuration sections below.
851#
852# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
853# that a given bus, target, and LUN always come on line as the same
854# device unit. In earlier versions the unit numbers were assigned
855# in the order that the devices were probed on the SCSI bus. This
856# means that if you removed a disk drive, you may have had to rewrite
857# your /etc/fstab file, and also that you had to be careful when adding
858# a new disk as it may have been probed earlier and moved your device
859# configuration around.
860
861# This old behavior is maintained as the default behavior. The unit
862# assignment begins with the first non-wired down unit for a device
863# type. For example, if you wire a disk as "da3" then the first
864# non-wired disk will be assigned da4.
865
866# The syntax for wiring down devices is:
867
868# device scbus0 at ahc0 # Single bus device
869# device scbus1 at ahc1 bus 0 # Single bus device
870# device scbus3 at ahc2 bus 0 # Twin bus device
871# device scbus2 at ahc2 bus 1 # Twin bus device
872# device da0 at scbus0 target 0 unit 0
873# device da1 at scbus3 target 1
874# device da2 at scbus2 target 3
875# device sa1 at scbus1 target 6
876# device cd
877
878# "units" (SCSI logical unit number) that are not specified are
879# treated as if specified as LUN 0.
880
881# All SCSI devices allocate as many units as are required.
