It works only with Cyrix FPU, and this option 124# should not be used with Intel FPU. 125# 126# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 127# CPU if CPU supports it. The default is double-clock mode on 128# BlueLightning CPU box. 129# 130# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 131# 132# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 133# mapped mode. Default is 2-way set associative mode. 134# 135# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 136# of Cyrix 6x86 and 6x86MX CPUs. If this option is not set and 137# FAILESAFE is defined, NO_LOCK bit of CCR1 is cleared. (NOTE 3) 138# 139# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 140# reorder).

Default vaules of 149# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 150# (no clock delay). 151# 152# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 153# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 154# 1). 155# 156# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 157# 158# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 159# enters suspend mode following execution of HALT instruction. 160# 161# CPU_WT_ALLOC enables write-through allocation. 162# 163# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 164# flush at hold state. 165# 166# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 167# without cache flush at hold state, and (2) write-back CPU cache on 168# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 169# 170# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 171# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 172# executed. This should be included for ALL kernels that won't run 173# on a Pentium. 174# 175# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 176# CPU_LOOP_ENand CPU_RSTK_EN should no be used becasue of CPU bugs. 177# These options may crash your system. 178# 179# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 180# in write-through mode when revision < 2.7. If revision of Cyrix 181# 6x86 >= 2.7, CPU cache is always enabled in write-back mode. 182# 183# NOTE 3: This option may cause failures for software that requires 184# locked cycles in order to operate correctly. 185# 186options "CPU_BLUELIGHTNING_FPU_OP_CACHE" 187options "CPU_BLUELIGHTNING_3X" 188options "CPU_BTB_EN" 189options "CPU_DIRECT_MAPPED_CACHE" 190options "CPU_DISABLE_5X86_LSSER" 191options "CPU_FASTER_5X86_FPU" 192options "CPU_I486_ON_386" 193options "CPU_IORT" 194options "CPU_LOOP_EN" 195options "CPU_RSTK_EN" 196options "CPU_SUSP_HLT" 197options "CYRIX_CACHE_WORKS" 198options "CYRIX_CACHE_REALLY_WORKS" 199#options "NO_F00F_HACK" 200 201# 202# A math emulator is mandatory if you wish to run on hardware which 203# does not have a floating-point processor.

The host adapters are listed in the ISA and PCI 545# device configuration sections below. 546# 547# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 548# that a given bus, target, and LUN always come on line as the same 549# device unit. In earlier versions the unit numbers were assigned 550# in the order that the devices were probed on the SCSI bus. This 551# means that if you removed a disk drive, you may have had to rewrite 552# your /etc/fstab file, and also that you had to be careful when adding 553# a new disk as it may have been probed earlier and moved your device 554# configuration around. 555 556# This old behavior is maintained as the default behavior. The unit 557# assignment begins with the first non-wired down unit for a device 558# type. For example, if you wire a disk as "sd3" then the first 559# non-wired disk will be assigned sd4. 560 561# The syntax for wiring down devices is: 562 563# controller scbus0 at ahc0 # Single bus device 564# controller scbus1 at ahc1 bus 0 # Single bus device 565# controller scbus3 at ahc2 bus 0 # Twin bus device 566# controller scbus2 at ahc2 bus 1 # Twin bus device 567# disk sd0 at scbus0 target 0 unit 0 568# disk sd1 at scbus3 target 1 569# disk sd2 at scbus2 target 3 570# tape st1 at scbus1 target 6 571# device cd0 at scbus? 572 573# "units" (SCSI logical unit number) that are not specified are 574# treated as if specified as LUN 0. 575 576# All SCSI devices allocate as many units as are required. 577 578# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 579# configuration and doesn't have to be explicitly configured. 580 581controller scbus0 #base SCSI code 582device ch0 #SCSI media changers 583device sd0 #SCSI disks 584device st0 #SCSI tapes 585device cd0 #SCSI CD-ROMs 586device od0 #SCSI optical disk 587 588# The previous devices (ch, sd, st, cd) are recognized by config. 589# config doesn't (and shouldn't) know about these newer ones, 590# so we have to specify that they are on a SCSI bus with the "at scbus?" 591# clause. 592 593device worm0 at scbus? # SCSI worm 594device pt0 at scbus? # SCSI processor type 595device sctarg0 at scbus? # SCSI target 596 597# SCSI OPTIONS: 598 599# SCSIDEBUG: When defined enables debugging macros 600# NO_SCSI_SENSE: When defined disables sense descriptions (about 4k) 601# SCSI_REPORT_GEOMETRY: Always report disk geometry at boot up instead 602# of only when booting verbosely. 603options SCSIDEBUG 604#options NO_SCSI_SENSE 605options SCSI_REPORT_GEOMETRY 606 607# Options for the `od' optical disk driver: 608# 609# If drive returns sense key as 0x02 with vendor specific additional 610# sense code (ASC) and additional sense code qualifier (ASCQ), or 611# illegal ASC and ASCQ.
