170# BlueLightning CPU. It works only with Cyrix FPU, and this option
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.
176#
177# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
178#
179# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
180# mapped mode. Default is 2-way set associative mode.

211# CPU_ELAN enables support for AMDs ElanSC520 CPU.
212#
213# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
214# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
215# 1).
216#
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
219# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
220#
221# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).

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

227# K5/K6/K6-2 cpus.
228#
229# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
230# flush at hold state.
231#
232# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
233# without cache flush at hold state, and (2) write-back CPU cache on
234# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
235#
236# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
237# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
238# executed. This option is only needed if I586_CPU is also defined,
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
243# occupied by an ISA memory hole.
244#
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
251# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

878# SCSI DEVICE CONFIGURATION
879
880# The SCSI subsystem consists of the `base' SCSI code, a number of
881# high-level SCSI device `type' drivers, and the low-level host-adapter
882# device drivers. The host adapters are listed in the ISA and PCI
883# device configuration sections below.
884#
885# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
886# that a given bus, target, and LUN always come on line as the same
887# device unit. In earlier versions the unit numbers were assigned
888# in the order that the devices were probed on the SCSI bus. This
889# means that if you removed a disk drive, you may have had to rewrite
890# your /etc/fstab file, and also that you had to be careful when adding
891# a new disk as it may have been probed earlier and moved your device
892# configuration around.
893
894# This old behavior is maintained as the default behavior. The unit
895# assignment begins with the first non-wired down unit for a device
896# type. For example, if you wire a disk as "da3" then the first
897# non-wired disk will be assigned da4.
898
899# The syntax for wiring down devices is:
900
901# device scbus0 at ahc0 # Single bus device
902# device scbus1 at ahc1 bus 0 # Single bus device
903# device scbus3 at ahc2 bus 0 # Twin bus device
904# device scbus2 at ahc2 bus 1 # Twin bus device
905# device da0 at scbus0 target 0 unit 0
906# device da1 at scbus3 target 1
907# device da2 at scbus2 target 3
908# device sa1 at scbus1 target 6
909# device cd
910
911# "units" (SCSI logical unit number) that are not specified are

1045#
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.
1049#
1050# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
1051# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1052# Automatic EOI is documented not to work for for the slave with the
1053# original i8259A, but it works for some clones and some integrated
1054# versions.
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
1063# be 131072 (128 * 1024).

1525# Notes on the Comtrol Rocketport driver:
1526#
1527# The exact values used for rp0 depend on how many boards you have

1529#
1530# Comtrol Rocketport ISA single card

1532#
1533# If instead you have two ISA cards, one installed at 0x100 and the
1534# second installed at 0x180, then you should add the following to
1535# your kernel configuration file:
1536#
1537# device rp0 at isa? port 0x100
1538# device rp1 at isa? port 0x180

1543# device rp1 at isa? port 0x100
1544# device rp2 at isa? port 0x340

1547# And for PCI cards, you only need say:
1548#
1549# device rp
1550
1551# Notes on the Digiboard driver:
1552#
1553# The following flag values have special meanings:
1554# 0x01 - alternate layout of pins (dgb & dgm)
1555# 0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1556
1557# Notes on the Specialix SI/XIO driver:
1558# **This is NOT a Specialix supported Driver!**
1559# The host card is memory, not IO mapped.
1560# The Rev 1 host cards use a 64K chunk, on a 32K boundary.
