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.

76# the limit.  MAXSSIZ is the maximum that the stack limit can be

315#  which throws away all packets sent and never receives any.  It is
316#  included for testing purposes.  This shows up as the 'ds' interface.
317#  The `tun' pseudo-device implements (user-)ppp and nos-tun
318#  The `gif' pseudo-device implements IPv6 over IP4 tunneling,
319#  IPv4 over IPv6 tunneling, IPv4 over IPv4 tunneling and
320#  IPv6 over IPv6 tunneling.
321#  The `gre' device implements two types of IP4 over IP4 tunneling:
322#  GRE and MOBILE, as specified in the RFC1701 and RFC2004.
323#  The `faith' pseudo-device captures packets sent to it and diverts them
324#  to the IPv4/IPv6 translation daemon.
325#  The `stf' device implements 6to4 encapsulation.

603# SCSI DEVICES
604
605# SCSI DEVICE CONFIGURATION
606
607# The SCSI subsystem consists of the `base' SCSI code, a number of
608# high-level SCSI device `type' drivers, and the low-level host-adapter
609# device drivers.  The host adapters are listed in the ISA and PCI
610# device configuration sections below.
611#
612# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
613# that a given bus, target, and LUN always come on line as the same
614# device unit.  In earlier versions the unit numbers were assigned
615# in the order that the devices were probed on the SCSI bus.  This
616# means that if you removed a disk drive, you may have had to rewrite
617# your /etc/fstab file, and also that you had to be careful when adding
618# a new disk as it may have been probed earlier and moved your device
619# configuration around.
620
621# This old behavior is maintained as the default behavior.  The unit
622# assignment begins with the first non-wired down unit for a device
623# type.  For example, if you wire a disk as "da3" then the first
624# non-wired disk will be assigned da4.
625
626# The syntax for wiring down devices is:
627
628# device	scbus0 at ahc0		# Single bus device
629# device	scbus1 at ahc1 bus 0	# Single bus device
630# device	scbus3 at ahc2 bus 0	# Twin bus device
631# device	scbus2 at ahc2 bus 1	# Twin bus device
632# device 	da0 at scbus0 target 0 unit 0
633# device	da1 at scbus3 target 1
634# device	da2 at scbus2 target 3
635# device	sa1 at scbus1 target 6
636# device	cd
637
638# "units" (SCSI logical unit number) that are not specified are
639# treated as if specified as LUN 0.
640
641# All SCSI devices allocate as many units as are required.
642

644# configuration and doesn't have to be explicitly configured.

1364# The 'sk' device provides support for the SysKonnect SK-984x series
1365# PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1366# single port cards (single mode and multimode fiber) and the
1367# SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1368# The driver will autodetect the number of ports on the card and
1369# attach each one as a separate network interface.
1370#
1371# The 'ti' device provides support for PCI gigabit ethernet NICs based
1372# on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1373# Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.
1374# Note that you will probably want to bump up NMBCLUSTERS a lot to use
1375# this driver.
1376#
1377# The 'tl' device provides support for the Texas Instruments TNETE100
1378# series 'ThunderLAN' cards and integrated ethernet controllers. This
1379# includes several Compaq Netelligent 10/100 cards and the built-in
1380# ethernet controllers in several Compaq Prosignia, Proliant and
1381# Deskpro systems. It also supports several Olicom 10Mbps and 10/100
1382# boards.
1383#
1384# The `tx' device provides support for the SMC 9432 TX, BTX and FTX cards.
1385#
1386# The `txp' device provides support for the 3Com 3cR990 "Typhoon"
1387# 10/100 adapters.
1388#
1389# The `vr' device provides support for various fast ethernet adapters
1390# based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1391# chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1392# Technologies PN102TX, and the AOpen/Acer ALN-320.
1393#
1394# The `wb' device provides support for various fast ethernet adapters
1395# based on the Winbond W89C840F chip. Note: this is not the same as
1396# the Winbond W89C940F, which is an NE2000 clone.
1397#
1398# The `xl' device provides support for the 3Com 3c900, 3c905 and
1399# 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1400# includes the integrated 3c905B-TX chips in certain Dell Optiplex and
1401# Dell Precision desktop machines and the integrated 3c905-TX chips
1402# in Dell Latitude laptop docking stations.
1403#
1404# The 'bktr' device is a PCI video capture device using the Brooktree
1405# bt848/bt848a/bt849a/bt878/bt879 chipset. When used with a TV Tuner it forms a
