29# The `maxusers' parameter controls the static sizing of a number of

40# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
41# after most other flags.  Here we use it to inhibit use of non-optimal
42# gcc builtin functions (e.g., memcmp).
43#
44# DEBUG happens to be magic.
45# The following is equivalent to 'config -g KERNELNAME' and creates
46# 'kernel.debug' compiled with -g debugging as well as a normal
47# 'kernel'.  Use 'make install.debug' to install the debug kernel
48# but that isn't normally necessary as the debug symbols are not loaded
49# by the kernel and are not useful there anyway.
50#
51# KERNEL can be overridden so that you can change the default name of your
52# kernel.
53#
54# MODULES_OVERRIDE can be used to limit modules built to a specific list.

56# INSTALLSTRIPPED can be set to cause installkernel to install stripped
57# kernels and modules rather than a kernel and modules with debug symbols.

60# installed, but to strip the installed modules.

76# the limit.  MAXSSIZ is the maximum that the stack limit can be
77# set to.  You might want to set the default lower than the max,
78# and explicitly set the maximum with a shell command for processes

292#  The `sppp' pseudo-device serves a similar role for certain types
293#  of synchronous PPP links.
294#  The `sl' pseudo-device implements the Serial Line IP (SLIP) service.
295#  The `bpf' pseudo-device enables the Berkeley Packet Filter.  Be
296#  aware of the legal and administrative consequences of enabling this
297#  option.  The number of devices determines the maximum number of
298#  simultaneous BPF clients programs runnable.
299#  The `disc' pseudo-device implements a minimal network interface,
300#  which throws away all packets sent and never receives any.  It is
301#  included for testing purposes.  This shows up as the 'ds' interface.
302#  The `tun' pseudo-device implements (user-)ppp and nos-tun
303#  The `gif' pseudo-device implements IPv6 over IP4 tunneling,
304#  IPv4 over IPv6 tunneling, IPv4 over IPv4 tunneling and

307#  GRE and MOBILE, as specified in the RFC1701 and RFC2004.
308#  The `stf' device implements 6to4 encapsulation.

580# SCSI DEVICES
581
582# SCSI DEVICE CONFIGURATION
583
584# The SCSI subsystem consists of the `base' SCSI code, a number of
585# high-level SCSI device `type' drivers, and the low-level host-adapter
586# device drivers.  The host adapters are listed in the ISA and PCI
587# device configuration sections below.
588#
589# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
590# that a given bus, target, and LUN always come on line as the same
591# device unit.  In earlier versions the unit numbers were assigned
592# in the order that the devices were probed on the SCSI bus.  This
593# means that if you removed a disk drive, you may have had to rewrite
594# your /etc/fstab file, and also that you had to be careful when adding
595# a new disk as it may have been probed earlier and moved your device
596# configuration around.
597
598# This old behavior is maintained as the default behavior.  The unit
599# assignment begins with the first non-wired down unit for a device
600# type.  For example, if you wire a disk as "da3" then the first
601# non-wired disk will be assigned da4.
602
603# The syntax for wiring down devices is:
604
605# device	scbus0 at ahc0		# Single bus device
606# device	scbus1 at ahc1 bus 0	# Single bus device
607# device	scbus3 at ahc2 bus 0	# Twin bus device
608# device	scbus2 at ahc2 bus 1	# Twin bus device
609# device 	da0 at scbus0 target 0 unit 0
610# device	da1 at scbus3 target 1
611# device	da2 at scbus2 target 3
612# device	sa1 at scbus1 target 6
613# device	cd
614
615# "units" (SCSI logical unit number) that are not specified are
616# treated as if specified as LUN 0.
617
618# All SCSI devices allocate as many units as are required.
619
620# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI
621# configuration and doesn't have to be explicitly configured.

1331# The 'rl' device provides support for PCI fast ethernet adapters based
1332# on the RealTek 8129/8139 chipset. Note that the RealTek driver defaults

1355# PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1356# single port cards (single mode and multimode fiber) and the
1357# SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1358# The driver will autodetect the number of ports on the card and
1359# attach each one as a separate network interface.
1360#
1361# The 'ti' device provides support for PCI gigabit ethernet NICs based
1362# on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1363# Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.
1364# Note that you will probably want to bump up NMBCLUSTERS a lot to use
1365# this driver.
1366#
1367# The 'tl' device provides support for the Texas Instruments TNETE100
1368# series 'ThunderLAN' cards and integrated ethernet controllers. This
1369# includes several Compaq Netelligent 10/100 cards and the built-in
1370# ethernet controllers in several Compaq Prosignia, Proliant and
1371# Deskpro systems. It also supports several Olicom 10Mbps and 10/100
1372# boards.
1373#
1374# The `tx' device provides support for the SMC 9432 TX, BTX and FTX cards.
1375#
1376# The `txp' device provides support for the 3Com 3cR990 "Typhoon"
1377# 10/100 adapters.
1378#
1379# The `vr' device provides support for various fast ethernet adapters
1380# based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1381# chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1382# Technologies PN102TX, and the AOpen/Acer ALN-320.
1383#
1384# The `wb' device provides support for various fast ethernet adapters
1385# based on the Winbond W89C840F chip. Note: this is not the same as
1386# the Winbond W89C940F, which is an NE2000 clone.
1387#
1388# The `xl' device provides support for the 3Com 3c900, 3c905 and
1389# 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1390# includes the integrated 3c905B-TX chips in certain Dell Optiplex and
1391# Dell Precision desktop machines and the integrated 3c905-TX chips
1392# in Dell Latitude laptop docking stations.
1393#
1394# The 'bktr' device is a PCI video capture device using the Brooktree
1395# bt848/bt848a/bt849a/bt878/bt879 chipset. When used with a TV Tuner it forms a
