171# should not be used with Intel FPU.
172#
173# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
174# CPU if CPU supports it. The default is double-clock mode on
175# BlueLightning CPU box.

177# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).

216# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
217# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
218# 1).
219#
220# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
221# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
222# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
223#
224# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
225#
226# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
227# enters suspend mode following execution of HALT instruction.

239# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
240# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
241# executed. This option is only needed if I586_CPU is also defined,
242# and should be included for any non-Pentium CPU that defines it.
243#
244# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
245# which indicates that the 15-16MB range is *definitely* not being
246# occupied by an ISA memory hole.
247#
248# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
249# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
250# These options may crash your system.
251#
252# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
253# in write-through mode when revision < 2.7. If revision of Cyrix
254# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

877# SCSI DEVICE CONFIGURATION
878
879# The SCSI subsystem consists of the `base' SCSI code, a number of
880# high-level SCSI device `type' drivers, and the low-level host-adapter
881# device drivers. The host adapters are listed in the ISA and PCI
882# device configuration sections below.
883#
884# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
885# that a given bus, target, and LUN always come on line as the same
886# device unit. In earlier versions the unit numbers were assigned
887# in the order that the devices were probed on the SCSI bus. This
888# means that if you removed a disk drive, you may have had to rewrite
889# your /etc/fstab file, and also that you had to be careful when adding
890# a new disk as it may have been probed earlier and moved your device
891# configuration around.
892
893# This old behavior is maintained as the default behavior. The unit
894# assignment begins with the first non-wired down unit for a device
895# type. For example, if you wire a disk as "da3" then the first
896# non-wired disk will be assigned da4.
897
898# The syntax for wiring down devices is:
899
900# device scbus0 at ahc0 # Single bus device
901# device scbus1 at ahc1 bus 0 # Single bus device
902# device scbus3 at ahc2 bus 0 # Twin bus device
903# device scbus2 at ahc2 bus 1 # Twin bus device
904# device da0 at scbus0 target 0 unit 0
905# device da1 at scbus3 target 1
906# device da2 at scbus2 target 3
907# device sa1 at scbus1 target 6

1045# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
1046# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1047# This option breaks suspend/resume on some portables.

1049# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A

1054#
1055# MAXMEM specifies the amount of RAM on the machine; if this is not
1056# specified, FreeBSD will first read the amount of memory from the CMOS
1057# RAM, so the amount of memory will initially be limited to 64MB or 16MB
1058# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
1059# then attempt to detect the installed amount of RAM. If this probe
1060# fails to detect >64MB RAM you will have to use the MAXMEM option.
