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

217# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
218# is useful when you use Socket 8 to Socket 370 converter, because most Pentium

230# flush at hold state.

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

239# and should be included for any non-Pentium CPU that defines it.
240#
241# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
242# which indicates that the 15-16MB range is *definitely* not being

245# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
246# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
247# These options may crash your system.
248#
249# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
250# in write-through mode when revision < 2.7. If revision of Cyrix

884# SCSI DEVICE CONFIGURATION
885
886# The SCSI subsystem consists of the `base' SCSI code, a number of
887# high-level SCSI device `type' drivers, and the low-level host-adapter
888# device drivers. The host adapters are listed in the ISA and PCI
889# device configuration sections below.
890#
891# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
892# that a given bus, target, and LUN always come on line as the same
893# device unit. In earlier versions the unit numbers were assigned
894# in the order that the devices were probed on the SCSI bus. This
895# means that if you removed a disk drive, you may have had to rewrite
896# your /etc/fstab file, and also that you had to be careful when adding
897# a new disk as it may have been probed earlier and moved your device
898# configuration around.
899
900# This old behavior is maintained as the default behavior. The unit
901# assignment begins with the first non-wired down unit for a device
902# type. For example, if you wire a disk as "da3" then the first
903# non-wired disk will be assigned da4.
904
905# The syntax for wiring down devices is:
906
907# device scbus0 at ahc0 # Single bus device
908# device scbus1 at ahc1 bus 0 # Single bus device
909# device scbus3 at ahc2 bus 0 # Twin bus device
910# device scbus2 at ahc2 bus 1 # Twin bus device
911# device da0 at scbus0 target 0 unit 0
912# device da1 at scbus3 target 1
913# device da2 at scbus2 target 3
914# device sa1 at scbus1 target 6
915# device cd
916
917# "units" (SCSI logical unit number) that are not specified are

1052# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
1053# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1054# This option breaks suspend/resume on some portables.

1056# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A

1058# Automatic EOI is documented not to work for for the slave with the

1061#
1062# MAXMEM specifies the amount of RAM on the machine; if this is not
1063# specified, FreeBSD will first read the amount of memory from the CMOS
1064# RAM, so the amount of memory will initially be limited to 64MB or 16MB
1065# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
1066# then attempt to detect the installed amount of RAM. If this probe
1067# fails to detect >64MB RAM you will have to use the MAXMEM option.
1068# The amount is in kilobytes, so for a machine with 128MB of RAM, it would

2431# (the /usr/sbin/svr4 script does this for you). If compiling statically,
2432# the `streams' pseudo-device must be configured into any kernel which also
2433# specifies COMPAT_SVR4. It is possible to have a statically-configured
2434# STREAMS device and a dynamically loadable svr4 emulator; the /usr/sbin/svr4
2435# script understands that it doesn't need to load the `streams' module under
2436# those circumstances.
