Instead, you should start from GENERIC, and add options from 9# this file as required. 10# 11 12# 13# This directive is mandatory; it defines the architecture to be 14# configured for; in this case, the 386 family. You must also specify 15# at least one CPU (the one you intend to run on); deleting the 16# specification for CPUs you don't need to use may make parts of the 17# system run faster. This is especially true removing I386_CPU. 18# 19machine "i386" 20cpu "I386_CPU" 21cpu "I486_CPU" 22cpu "I586_CPU" # aka Pentium(tm) 23cpu "I686_CPU" # aka Pentium Pro(tm) 24 25# 26# This is the ``identification'' of the kernel.

E.g., (1) in a large news server, user 41# `news' may need more than 100 concurrent processes. (2) a user may 42# need lots of windows under X. In both cases, it may be inconvenient 43# to start all the processes from a parent whose soft rlimit on the 44# number of processes is large enough. The following options work by 45# changing the soft rlimits for init. 46# 47options CHILD_MAX=128 48options OPEN_MAX=128 49 50# 51# Certain applications can grow to be larger than the 128M limit 52# that FreeBSD initially imposes. Below are some options to 53# allow that limit to grow to 256MB, and can be increased further 54# with changing the parameters. MAXDSIZ is the maximum that the 55# limit can be set to, and the DFLDSIZ is the default value for 56# the limit. You might want to set the default lower than the 57# max, and explicitly set the maximum with a shell command for processes 58# that regularly exceed the limit like INND. 59# 60options "MAXDSIZ=(256*1024*1024)" 61options "DFLDSIZ=(256*1024*1024)" 62 63# 64# A math emulator is mandatory if you wish to run on hardware which 65# does not have a floating-point processor.

The host adapters are listed in the ISA and PCI 338# device configuration sections below. 339# 340# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 341# that a given bus, target, and LUN always come on line as the same 342# device unit. In earlier versions the unit numbers were assigned 343# in the order that the devices were probed on the SCSI bus. This 344# means that if you removed a disk drive, you may have had to rewrite 345# your /etc/fstab file, and also that you had to be careful when adding 346# a new disk as it may have been probed earlier and moved your device 347# configuration around. 348 349# This old behavior is maintained as the default behavior. The unit 350# assignment begins with the first non-wired down unit for a device 351# type. For example, if you wire a disk as "sd3" then the first 352# non-wired disk will be assigned sd4. 353 354# The syntax for wiring down devices is: 355 356# controller scbus0 at ahc0 # Single bus device 357# controller scbus1 at ahc1 bus 0 # Single bus device 358# controller scbus3 at ahc2 bus 0 # Twin bus device 359# controller scbus2 at ahc2 bus 1 # Twin bus device 360# disk sd0 at scbus0 target 0 unit 0 361# disk sd1 at scbus3 target 1 362# disk sd2 at scbus2 target 3 363# tape st1 at scbus1 target 6 364# device cd0 at scbus? 365 366# "units" (SCSI logical unit number) that are not specified are 367# treated as if specified as LUN 0. 368 369# All SCSI devices allocate as many units as are required. 370 371# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 372# configuration and doesn't have to be explicitly configured. 373 374controller scbus0 #base SCSI code 375device ch0 #SCSI media changers 376device sd0 #SCSI disks 377device st0 #SCSI tapes 378device cd0 #SCSI CD-ROMs 379device od0 #SCSI optical disk 380 381# The previous devices (ch, sd, st, cd) are recognized by config. 382# config doesn't (and shouldn't) know about these newer ones, 383# so we have to specify that they are on a SCSI bus with the "at scbus?" 384# clause. 385 386device worm0 at scbus? # SCSI worm 387device pt0 at scbus? # SCSI processor type 388device sctarg0 at scbus? # SCSI target 389 390# SCSI OPTIONS: 391 392# SCSIDEBUG: When defined enables debugging macros 393# NO_SCSI_SENSE: When defined disables sense descriptions (about 4k) 394# SCSI_REPORT_GEOMETRY: Always report disk geometry at boot up instead 395# of only when booting verbosely. 396options SCSIDEBUG 397#options NO_SCSI_SENSE 398options SCSI_REPORT_GEOMETRY 399 400# Options for the `od' optical disk driver: 401# 402# If drive returns sense key as 0x02 with vendor specific additional 403# sense code (ASC) and additional sense code qualifier (ASCQ), or 404# illegal ASC and ASCQ.
