(an example is a large news server in which 41# the uid, news, can sometimes need > 100 simultaneous processes running, 42# or perhaps a user using lots of windows under X). 43options CHILD_MAX=128 44options OPEN_MAX=128 45 46# 47# Under some circumstances it is useful to have an extra number of 48# vnode data structures allocated at boot time. In particular, 49# usenet news servers can benefit if there are enough vnodes to 50# cache the busiest newsgroup and overview directories. Beware that 51# this is an expensive option, it consumes physical non-pageable ram. 52# A busy news server may benefit from 10,000 extra vnodes or so. 53# 54options EXTRAVNODES=1 55 56# 57# A math emulator is mandatory if you wish to run on hardware which 58# does not have a floating-point processor.

The host adapters are listed in the ISA and PCI 322# device configuration sections below. 323# 324# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 325# that a given bus, target, and LUN always come on line as the same 326# device unit. In earlier versions the unit numbers were assigned 327# in the order that the devices were probed on the SCSI bus. This 328# means that if you removed a disk drive, you may have had to rewrite 329# your /etc/fstab file, and also that you had to be careful when adding 330# a new disk as it may have been probed earlier and moved your device 331# configuration around. 332 333# This old behavior is maintained as the default behavior. The unit 334# assignment begins with the first non-wired down unit for a device 335# type. For example, if you wire a disk as "sd3" then the first 336# non-wired disk will be assigned sd4. 337 338# The syntax for wiring down devices is: 339 340# controller scbus0 at ahc0 # Single bus device 341# controller scbus1 at ahc1 bus 0 # Single bus device 342# controller scbus3 at ahc2 bus 0 # Twin bus device 343# controller scbus2 at ahc2 bus 1 # Twin bus device 344# disk sd0 at scbus0 target 0 unit 0 345# disk sd1 at scbus3 target 1 346# disk sd2 at scbus2 target 3 347# tape st1 at scbus1 target 6 348# device cd0 at scbus? 349 350# "units" (SCSI logical unit number) that are not specified are 351# treated as if specified as LUN 0. 352 353# All SCSI devices allocate as many units as are required. 354 355# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 356# configuration and doesn't have to be explicitly configured. 357 358controller scbus0 #base SCSI code 359device ch0 #SCSI media changers 360device sd0 #SCSI disks 361device st0 #SCSI tapes 362device cd0 #SCSI CD-ROMs 363device od0 #SCSI optical disk 364 365# The previous devices (ch, sd, st, cd) are recognized by config. 366# config doesn't (and shouldn't) know about these newer ones, 367# so we have to specify that they are on a SCSI bus with the "at scbus?" 368# clause. 369 370device worm0 at scbus? # SCSI worm 371device pt0 at scbus? # SCSI processor type 372device sctarg0 at scbus? # SCSI target 373 374# SCSI OPTIONS: 375 376# SCSIDEBUG: When defined enables debugging macros 377# NO_SCSI_SENSE: When defined disables sense descriptions (about 4k) 378# SCSI_REPORT_GEOMETRY: Always report disk geometry at boot up instead 379# of only when booting verbosely. 380options SCSIDEBUG 381#options NO_SCSI_SENSE 382options SCSI_REPORT_GEOMETRY 383 384# Options for the `od' optical disk driver: 385# 386# If drive returns sense key as 0x02 with vendor specific additional 387# sense code (ASC) and additional sense code qualifier (ASCQ), or 388# illegal ASC and ASCQ.
