170#
171# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning

237# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
238# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
239# executed. This option is only needed if I586_CPU is also defined,
240# and should be included for any non-Pentium CPU that defines it.
241#
242# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
243# which indicates that the 15-16MB range is *definitely* not being

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

874
875# SCSI DEVICE CONFIGURATION
876
877# The SCSI subsystem consists of the `base' SCSI code, a number of
878# high-level SCSI device `type' drivers, and the low-level host-adapter
879# device drivers. The host adapters are listed in the ISA and PCI
880# device configuration sections below.
881#
882# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
883# that a given bus, target, and LUN always come on line as the same
884# device unit. In earlier versions the unit numbers were assigned
885# in the order that the devices were probed on the SCSI bus. This
886# means that if you removed a disk drive, you may have had to rewrite
887# your /etc/fstab file, and also that you had to be careful when adding
888# a new disk as it may have been probed earlier and moved your device
889# configuration around.
890
891# This old behavior is maintained as the default behavior. The unit
892# assignment begins with the first non-wired down unit for a device
893# type. For example, if you wire a disk as "da3" then the first
894# non-wired disk will be assigned da4.
895
896# The syntax for wiring down devices is:
897
898# device scbus0 at ahc0 # Single bus device
899# device scbus1 at ahc1 bus 0 # Single bus device
900# device scbus3 at ahc2 bus 0 # Twin bus device
901# device scbus2 at ahc2 bus 1 # Twin bus device
902# device da0 at scbus0 target 0 unit 0
903# device da1 at scbus3 target 1
904# device da2 at scbus2 target 3
905# device sa1 at scbus1 target 6

1046# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
1047# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1048# This option breaks suspend/resume on some portables.

1050# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A

1052# Automatic EOI is documented not to work for for the slave with the

1055#
1056# MAXMEM specifies the amount of RAM on the machine; if this is not
1057# specified, FreeBSD will first read the amount of memory from the CMOS
1058# RAM, so the amount of memory will initially be limited to 64MB or 16MB
1059# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
1060# then attempt to detect the installed amount of RAM. If this probe
1061# fails to detect >64MB RAM you will have to use the MAXMEM option.
1062# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
