157# CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has
158# forgotten to enable them.
159#
160# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
161# BlueLightning CPU. It works only with Cyrix FPU, and this option
162# should not be used with Intel FPU.
163#
164# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
165# CPU if CPU supports it. The default is double-clock mode on
166# BlueLightning CPU box.
167#
168# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
169#
170# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
171# mapped mode. Default is 2-way set associative mode.
172#
173# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
174# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
175# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
176#
177# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
178# reorder). This option should not be used if you use memory mapped
179# I/O device(s).
180#
181# CPU_DISABLE_SSE disables SSE/MMX2 instructions support.
182#
183# CPU_ENABLE_TCC enables Thermal Control Circuitry (TCC) found in some
184# Pentium(tm) 4 and (possibly) later CPUs. When enabled and detected,
185# TCC supports restricting power consumption using the hw.p4tcc.*
186# sysctls. This operates independently of SpeedStep and is useful on
187# systems where other mechanisms such as apm(4) or acpi(4) don't work.
188#
189# CPU_FASTER_5X86_FPU enables faster FPU exception handler.

191# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
192# for i386 machines.
193#
194# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of
195# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
196# (no clock delay).
197#
198# CPU_L2_LATENCY specifed the L2 cache latency value. This option is used
199# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
200# The default value is 5.
201#
202# CPU_ELAN enables support for AMDs ElanSC520 CPU.
203#
204# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
205# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
206# 1).
207#
208# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
209# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
210# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
211#
212# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
213#
214# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
215# enters suspend mode following execution of HALT instruction.
216#
217# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
218# K5/K6/K6-2 cpus.
219#
220# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
221# flush at hold state.
222#
223# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
224# without cache flush at hold state, and (2) write-back CPU cache on
225# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
226#
227# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
228# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
229# executed. This option is only needed if I586_CPU is also defined,
230# and should be included for any non-Pentium CPU that defines it.
231#
232# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
233# which indicates that the 15-16MB range is *definitely* not being
234# occupied by an ISA memory hole.
235#
236# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
237# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
238# These options may crash your system.
239#
240# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
241# in write-through mode when revision < 2.7. If revision of Cyrix

869# SCSI DEVICE CONFIGURATION
870
871# The SCSI subsystem consists of the `base' SCSI code, a number of
872# high-level SCSI device `type' drivers, and the low-level host-adapter
873# device drivers. The host adapters are listed in the ISA and PCI
874# device configuration sections below.
875#
876# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
877# that a given bus, target, and LUN always come on line as the same
878# device unit. In earlier versions the unit numbers were assigned
879# in the order that the devices were probed on the SCSI bus. This
880# means that if you removed a disk drive, you may have had to rewrite
881# your /etc/fstab file, and also that you had to be careful when adding
882# a new disk as it may have been probed earlier and moved your device
883# configuration around.
884
885# This old behavior is maintained as the default behavior. The unit
886# assignment begins with the first non-wired down unit for a device
887# type. For example, if you wire a disk as "da3" then the first
888# non-wired disk will be assigned da4.
889
890# The syntax for wiring down devices is:
891
892# device scbus0 at ahc0 # Single bus device
893# device scbus1 at ahc1 bus 0 # Single bus device
894# device scbus3 at ahc2 bus 0 # Twin bus device
895# device scbus2 at ahc2 bus 1 # Twin bus device
896# device da0 at scbus0 target 0 unit 0
897# device da1 at scbus3 target 1

1537# The following flag values have special meanings:
1538# 0x01 - alternate layout of pins (dgb & dgm)
1539# 0x02 - use the windowed PC/Xe in 64K mode (dgb only)

1542# **This is NOT a Specialix supported Driver!**
1543# The host card is memory, not IO mapped.
1544# The Rev 1 host cards use a 64K chunk, on a 32K boundary.

1551# The stl driver has a secondary IO port hard coded at 0x280. You need
1552# to change src/i386/isa/stallion.c if you reconfigure this on the boards.
1553# The "flags" and "iosiz" settings on the stli driver depend on the board:

2432# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
2433# The DPT controllers are commonly re-licensed under other brand-names -
2434# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
2435# Compaq are actually DPT controllers.
2436#
2437# See src/sys/dev/dpt for debugging and other subtle options.
2438# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
2439# instruments are enabled. The tools in
2440# /usr/sbin/dpt_* assume these to be enabled.
2441# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
2442# If you ant the driver to handle timeouts, enable
2443# this option. If your system is very busy, this
2444# option will create more trouble than solve.
2445# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
2446# wait when timing out with the above option.
2447# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
2448# DPT_LOST_IRQ When enabled, will try, once per second, to catch
2449# any interrupt that got lost. Seems to help in some
2450# DPT-firmware/Motherboard combinations. Minimal
2451# cost, great benefit.
2452# DPT_RESET_HBA Make "reset" actually reset the controller
2453# instead of fudging it. Only enable this if you
2454# are 100% certain you need it.
