This is especially true removing 117# I386_CPU. 118# 119cpu "I386_CPU" 120cpu "I486_CPU" 121cpu "I586_CPU" # aka Pentium(tm) 122cpu "I686_CPU" # aka Pentium Pro(tm) 123 124# 125# Options for CPU features. 126# 127# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM 128# BlueLightning CPU. It works only with Cyrix FPU, and this option 129# should not be used with Intel FPU. 130# 131# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 132# CPU if CPU supports it. The default is double-clock mode on 133# BlueLightning CPU box. 134# 135# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 136# 137# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 138# mapped mode. Default is 2-way set associative mode. 139# 140# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 141# of Cyrix 6x86 and 6x86MX CPUs. If this option is not set and 142# FAILESAFE is defined, NO_LOCK bit of CCR1 is cleared. (NOTE 3) 143# 144# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 145# reorder). This option should not be used if you use memory mapped 146# I/O device(s). 147# 148# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 149# 150# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 151# for i386 machines. 152# 153# CPU_IORT defines I/O clock delay time (NOTE 1). Default vaules of 154# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 155# (no clock delay). 156# 157# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 158# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 159# 1). 160# 161# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 162# 163# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 164# enters suspend mode following execution of HALT instruction. 165# 166# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 167# K5/K6/K6-2 cpus. 168# 169# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 170# flush at hold state. 171# 172# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 173# without cache flush at hold state, and (2) write-back CPU cache on 174# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 175# 176# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 177# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 178# executed. This should be included for ALL kernels that won't run 179# on a Pentium. 180# 181# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 182# which indicates that the 15-16MB range is *definitely* not being 183# occupied by an ISA memory hole. 184# 185# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 186# CPU_LOOP_ENand CPU_RSTK_EN should not be used becasue of CPU bugs. 187# These options may crash your system. 188# 189# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 190# in write-through mode when revision < 2.7. If revision of Cyrix 191# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 192# 193# NOTE 3: This option may cause failures for software that requires 194# locked cycles in order to operate correctly. 195# 196options "CPU_BLUELIGHTNING_FPU_OP_CACHE" 197options "CPU_BLUELIGHTNING_3X" 198options "CPU_BTB_EN" 199options "CPU_DIRECT_MAPPED_CACHE" 200options "CPU_DISABLE_5X86_LSSER" 201options "CPU_FASTER_5X86_FPU" 202options "CPU_I486_ON_386" 203options "CPU_IORT" 204options "CPU_LOOP_EN" 205options "CPU_RSTK_EN" 206options "CPU_SUSP_HLT" 207options "CPU_WT_ALLOC" 208options "CYRIX_CACHE_WORKS" 209options "CYRIX_CACHE_REALLY_WORKS" 210#options "NO_F00F_HACK" 211 212# 213# A math emulator is mandatory if you wish to run on hardware which 214# does not have a floating-point processor.

It is a prerequisite for 311# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 312# called. The intent is that you can set 'INVARIANTS' for single 313# source files (by changing the source file or specifying it on the 314# command line) if you have 'INVARIANT_SUPPORT' enabled. 315# 316options INVARIANT_SUPPORT 317 318# 319# The DIAGNOSTIC option is used to enable extra debugging information 320# from some parts of the kernel.

The host adapters are listed in the ISA and PCI 653# device configuration sections below. 654# 655# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 656# that a given bus, target, and LUN always come on line as the same 657# device unit. In earlier versions the unit numbers were assigned 658# in the order that the devices were probed on the SCSI bus. This 659# means that if you removed a disk drive, you may have had to rewrite 660# your /etc/fstab file, and also that you had to be careful when adding 661# a new disk as it may have been probed earlier and moved your device 662# configuration around. 663 664# This old behavior is maintained as the default behavior. The unit 665# assignment begins with the first non-wired down unit for a device 666# type. For example, if you wire a disk as "da3" then the first 667# non-wired disk will be assigned da4. 668 669# The syntax for wiring down devices is: 670 671# controller scbus0 at ahc0 # Single bus device 672# controller scbus1 at ahc1 bus 0 # Single bus device 673# controller scbus3 at ahc2 bus 0 # Twin bus device 674# controller scbus2 at ahc2 bus 1 # Twin bus device 675# disk da0 at scbus0 target 0 unit 0 676# disk da1 at scbus3 target 1 677# disk da2 at scbus2 target 3 678# tape st1 at scbus1 target 6 679# device cd0 at scbus? 680 681# "units" (SCSI logical unit number) that are not specified are 682# treated as if specified as LUN 0. 683 684# All SCSI devices allocate as many units as are required. 685 686# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 687# configuration and doesn't have to be explicitly configured. 688 689controller scbus0 #base SCSI code 690device ch0 #SCSI media changers 691device da0 #SCSI direct access devices (aka disks) 692device sa0 #SCSI tapes 693device cd0 #SCSI CD-ROMs 694#device od0 #SCSI optical disk 695device pass0 #CAM passthrough driver 696 697# The previous devices (ch, da, st, cd) are recognized by config. 698# config doesn't (and shouldn't) know about these newer ones, 699# so we have to specify that they are on a SCSI bus with the "at scbus?" 700# clause. 701 702device pt0 at scbus? # SCSI processor type 703device sctarg0 at scbus? # SCSI target 704 705# CAM OPTIONS: 706# debugging options: 707# -- NOTE -- If you specify one of the bus/target/lun options, you must 708# specify them all! 709# CAMDEBUG: When defined enables debugging macros 710# CAM_DEBUG_BUS: Debug the given bus.
