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 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.

The host adapters are listed in the ISA and PCI 503# device configuration sections below. 504# 505# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 506# that a given bus, target, and LUN always come on line as the same 507# device unit. In earlier versions the unit numbers were assigned 508# in the order that the devices were probed on the SCSI bus. This 509# means that if you removed a disk drive, you may have had to rewrite 510# your /etc/fstab file, and also that you had to be careful when adding 511# a new disk as it may have been probed earlier and moved your device 512# configuration around. 513 514# This old behavior is maintained as the default behavior. The unit 515# assignment begins with the first non-wired down unit for a device 516# type. For example, if you wire a disk as "sd3" then the first 517# non-wired disk will be assigned sd4. 518 519# The syntax for wiring down devices is: 520 521# controller scbus0 at ahc0 # Single bus device 522# controller scbus1 at ahc1 bus 0 # Single bus device 523# controller scbus3 at ahc2 bus 0 # Twin bus device 524# controller scbus2 at ahc2 bus 1 # Twin bus device 525# disk sd0 at scbus0 target 0 unit 0 526# disk sd1 at scbus3 target 1 527# disk sd2 at scbus2 target 3 528# tape st1 at scbus1 target 6 529# device cd0 at scbus? 530 531# "units" (SCSI logical unit number) that are not specified are 532# treated as if specified as LUN 0. 533 534# All SCSI devices allocate as many units as are required. 535 536# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 537# configuration and doesn't have to be explicitly configured. 538 539controller scbus0 #base SCSI code 540device ch0 #SCSI media changers 541device sd0 #SCSI disks 542device st0 #SCSI tapes 543device cd0 #SCSI CD-ROMs 544device od0 #SCSI optical disk 545 546# The previous devices (ch, sd, st, cd) are recognized by config. 547# config doesn't (and shouldn't) know about these newer ones, 548# so we have to specify that they are on a SCSI bus with the "at scbus?" 549# clause. 550 551device worm0 at scbus? # SCSI worm 552device pt0 at scbus? # SCSI processor type 553device sctarg0 at scbus? # SCSI target 554 555# SCSI OPTIONS: 556 557# SCSIDEBUG: When defined enables debugging macros 558# NO_SCSI_SENSE: When defined disables sense descriptions (about 4k) 559# SCSI_REPORT_GEOMETRY: Always report disk geometry at boot up instead 560# of only when booting verbosely. 561options SCSIDEBUG 562#options NO_SCSI_SENSE 563options SCSI_REPORT_GEOMETRY 564 565# Options for the `od' optical disk driver: 566# 567# If drive returns sense key as 0x02 with vendor specific additional 568# sense code (ASC) and additional sense code qualifier (ASCQ), or 569# illegal ASC and ASCQ.
