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.
541#
542# The PPP_BSDCOMP option enables support for compress(1) style entire
543# packet compression, the PPP_DEFLATE is for zlib/gzip style compression.
544# PPP_FILTER enables code for filtering the ppp data stream and selecting

881
882# SCSI DEVICE CONFIGURATION
883
884# The SCSI subsystem consists of the `base' SCSI code, a number of
885# high-level SCSI device `type' drivers, and the low-level host-adapter
886# device drivers. The host adapters are listed in the ISA and PCI
887# device configuration sections below.
888#
889# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
890# that a given bus, target, and LUN always come on line as the same
891# device unit. In earlier versions the unit numbers were assigned
892# in the order that the devices were probed on the SCSI bus. This
893# means that if you removed a disk drive, you may have had to rewrite
894# your /etc/fstab file, and also that you had to be careful when adding
895# a new disk as it may have been probed earlier and moved your device
896# configuration around.
897
898# This old behavior is maintained as the default behavior. The unit
899# assignment begins with the first non-wired down unit for a device
900# type. For example, if you wire a disk as "da3" then the first
901# non-wired disk will be assigned da4.
902
903# The syntax for wiring down devices is:
904
905# device scbus0 at ahc0 # Single bus device
906# device scbus1 at ahc1 bus 0 # Single bus device
907# device scbus3 at ahc2 bus 0 # Twin bus device
908# device scbus2 at ahc2 bus 1 # Twin bus device
909# device da0 at scbus0 target 0 unit 0
910# device da1 at scbus3 target 1
911# device da2 at scbus2 target 3
912# device sa1 at scbus1 target 6
913# device cd
914
915# "units" (SCSI logical unit number) that are not specified are

1049#
1050# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
1051# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1052# This option breaks suspend/resume on some portables.
1053#
1054# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
1055# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1056# Automatic EOI is documented not to work for for the slave with the
1057# original i8259A, but it works for some clones and some integrated
1058# versions.
1059#
1060# MAXMEM specifies the amount of RAM on the machine; if this is not
1061# specified, FreeBSD will first read the amount of memory from the CMOS
1062# RAM, so the amount of memory will initially be limited to 64MB or 16MB
1063# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
1064# then attempt to detect the installed amount of RAM. If this probe
1065# fails to detect >64MB RAM you will have to use the MAXMEM option.
1066# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
1067# be 131072 (128 * 1024).
