512# Network interfaces:
513# The `loop' pseudo-device is MANDATORY when networking is enabled.
514# The `ether' pseudo-device provides generic code to handle
515# Ethernets; it is MANDATORY when a Ethernet device driver is
516# configured or token-ring is enabled.
517# The 'fddi' pseudo-device provides generic code to support FDDI.
518# The `arcnet' pseudo-device provides generic code to support Arcnet.
519# The `sppp' pseudo-device serves a similar role for certain types
520# of synchronous PPP links (like `cx', `ar').
521# The `sl' pseudo-device implements the Serial Line IP (SLIP) service.
522# The `ppp' pseudo-device implements the Point-to-Point Protocol.
523# The `bpf' pseudo-device enables the Berkeley Packet Filter. Be
524# aware of the legal and administrative consequences of enabling this
525# option. The number of devices determines the maximum number of
526# simultaneous BPF clients programs runnable.
527# The `disc' pseudo-device implements a minimal network interface,
528# which throws away all packets sent and never receives any. It is
529# included for testing purposes. This shows up as the 'ds' interface.
530# The `tun' pseudo-device implements (user-)ppp and nos-tun
531# The `gif' pseudo-device implements IPv6 over IP4 tunneling,
532# IPv4 over IPv6 tunneling, IPv4 over IPv4 tunneling and
533# IPv6 over IPv6 tunneling.
534# The `gre' device implements two types of IP4 over IP4 tunneling:
535# GRE and MOBILE, as specified in the RFC1701 and RFC2004.
536# The `faith' pseudo-device captures packets sent to it and diverts them
537# to the IPv4/IPv6 translation daemon.
538# The `stf' device implements 6to4 encapsulation.
539# The `ef' pseudo-device provides support for multiple ethernet frame types
540# specified via ETHER_* options. See ef(4) for details.

542# The PPP_BSDCOMP option enables support for compress(1) style entire

875# SCSI DEVICE CONFIGURATION
876
877# The SCSI subsystem consists of the `base' SCSI code, a number of
878# high-level SCSI device `type' drivers, and the low-level host-adapter
879# device drivers. The host adapters are listed in the ISA and PCI
880# device configuration sections below.
881#
882# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
883# that a given bus, target, and LUN always come on line as the same
884# device unit. In earlier versions the unit numbers were assigned
885# in the order that the devices were probed on the SCSI bus. This
886# means that if you removed a disk drive, you may have had to rewrite
887# your /etc/fstab file, and also that you had to be careful when adding
888# a new disk as it may have been probed earlier and moved your device
889# configuration around.
890
891# This old behavior is maintained as the default behavior. The unit
892# assignment begins with the first non-wired down unit for a device
893# type. For example, if you wire a disk as "da3" then the first
894# non-wired disk will be assigned da4.
895
896# The syntax for wiring down devices is:
897
898# device scbus0 at ahc0 # Single bus device
899# device scbus1 at ahc1 bus 0 # Single bus device
900# device scbus3 at ahc2 bus 0 # Twin bus device
901# device scbus2 at ahc2 bus 1 # Twin bus device
902# device da0 at scbus0 target 0 unit 0
903# device da1 at scbus3 target 1
904# device da2 at scbus2 target 3
905# device sa1 at scbus1 target 6

1043# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
1044# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1045# This option breaks suspend/resume on some portables.
1046#
1047# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
1048# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1049# Automatic EOI is documented not to work for for the slave with the

1051# versions.
1052#
1053# MAXMEM specifies the amount of RAM on the machine; if this is not
1054# specified, FreeBSD will first read the amount of memory from the CMOS
1055# RAM, so the amount of memory will initially be limited to 64MB or 16MB
1056# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
1057# then attempt to detect the installed amount of RAM. If this probe
1058# fails to detect >64MB RAM you will have to use the MAXMEM option.

1829# ethernet controllers in several Compaq Prosignia, Proliant and
1830# Deskpro systems. It also supports several Olicom 10Mbps and 10/100
1831# boards.
1832#
1833# The `tx' device provides support for the SMC 9432 TX, BTX and FTX cards.

1836# 10/100 adapters.
1837#
1838# The `vr' device provides support for various fast ethernet adapters
1839# based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1840# chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1841# Technologies PN102TX, and the AOpen/Acer ALN-320.
1842#
1843# The `vx' device provides support for the 3Com 3C590 and 3C595
1844# early support
1845#
1846# The `wb' device provides support for various fast ethernet adapters
1847# based on the Winbond W89C840F chip. Note: this is not the same as
1848# the Winbond W89C940F, which is an NE2000 clone.

1850# The `xl' device provides support for the 3Com 3c900, 3c905 and
1851# 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1852# includes the integrated 3c905B-TX chips in certain Dell Optiplex and
1853# Dell Precision desktop machines and the integrated 3c905-TX chips
1854# in Dell Latitude laptop docking stations.
1855#
1856# The `fpa' device provides support for the Digital DEFPA PCI FDDI
1857# adapter. pseudo-device fddi is also needed.

1859# The `meteor' device is a PCI video capture board. It can also have the
1860# following options:
1861# options METEOR_ALLOC_PAGES=xxx preallocate kernel pages for data entry
1862# figure (ROWS*COLUMN*BYTES_PER_PIXEL*FRAME+PAGE_SIZE-1)/PAGE_SIZE
1863# options METEOR_DEALLOC_PAGES remove all allocated pages on close(2)

1870# The 'bktr' device is a PCI video capture device using the Brooktree
1871# bt848/bt848a/bt849a/bt878/bt879 chipset. When used with a TV Tuner it forms a
1872# TV card, eg Miro PC/TV, Hauppauge WinCast/TV WinTV, VideoLogic Captivator,
