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

32# memory.

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.
55#
56# INSTALLSTRIPPED can be set to cause installkernel to install stripped
57# kernels and modules rather than a kernel and modules with debug symbols.
58#
59# INSTALLSTRIPPEDMODULES can be set to allow a full debug kernel to be
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

287#  The `sppp' pseudo-device serves a similar role for certain types
288#  of synchronous PPP links.
289#  The `sl' pseudo-device implements the Serial Line IP (SLIP) service.
290#  The `bpf' pseudo-device enables the Berkeley Packet Filter.  Be
291#  aware of the legal and administrative consequences of enabling this

295#  which throws away all packets sent and never receives any.  It is
296#  included for testing purposes.  This shows up as the 'ds' interface.
297#  The `tun' pseudo-device implements (user-)ppp and nos-tun
298#  The `gif' pseudo-device implements IPv6 over IP4 tunneling,
299#  IPv4 over IPv6 tunneling, IPv4 over IPv4 tunneling and

578# SCSI DEVICES
579
580# SCSI DEVICE CONFIGURATION
581
582# The SCSI subsystem consists of the `base' SCSI code, a number of
583# high-level SCSI device `type' drivers, and the low-level host-adapter
584# device drivers.  The host adapters are listed in the ISA and PCI
585# device configuration sections below.
586#
587# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
588# that a given bus, target, and LUN always come on line as the same
589# device unit.  In earlier versions the unit numbers were assigned
590# in the order that the devices were probed on the SCSI bus.  This
591# means that if you removed a disk drive, you may have had to rewrite
592# your /etc/fstab file, and also that you had to be careful when adding
593# a new disk as it may have been probed earlier and moved your device
594# configuration around.
595
596# This old behavior is maintained as the default behavior.  The unit
597# assignment begins with the first non-wired down unit for a device
598# type.  For example, if you wire a disk as "da3" then the first
599# non-wired disk will be assigned da4.
600
601# The syntax for wiring down devices is:
602
603# device	scbus0 at ahc0		# Single bus device
604# device	scbus1 at ahc1 bus 0	# Single bus device
605# device	scbus3 at ahc2 bus 0	# Twin bus device
606# device	scbus2 at ahc2 bus 1	# Twin bus device
607# device 	da0 at scbus0 target 0 unit 0
608# device	da1 at scbus3 target 1
609# device	da2 at scbus2 target 3
610# device	sa1 at scbus1 target 6
611# device	cd
612
613# "units" (SCSI logical unit number) that are not specified are
614# treated as if specified as LUN 0.
615
616# All SCSI devices allocate as many units as are required.
617
618# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI
619# configuration and doesn't have to be explicitly configured.

1354# PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1355# single port cards (single mode and multimode fiber) and the
1356# SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1357# The driver will autodetect the number of ports on the card and
1358# attach each one as a separate network interface.
1359#
1360# The 'ti' device provides support for PCI gigabit ethernet NICs based
1361# on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1362# Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.
1363# Note that you will probably want to bump up NMBCLUSTERS a lot to use
1364# this driver.
1365#
1366# The 'tl' device provides support for the Texas Instruments TNETE100
1367# series 'ThunderLAN' cards and integrated ethernet controllers. This
1368# includes several Compaq Netelligent 10/100 cards and the built-in
1369# ethernet controllers in several Compaq Prosignia, Proliant and
1370# Deskpro systems. It also supports several Olicom 10Mbps and 10/100
1371# boards.
1372#
1373# The `tx' device provides support for the SMC 9432 TX, BTX and FTX cards.
1374#
1375# The `txp' device provides support for the 3Com 3cR990 "Typhoon"
1376# 10/100 adapters.
1377#
1378# The `vr' device provides support for various fast ethernet adapters
1379# based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1380# chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1381# Technologies PN102TX, and the AOpen/Acer ALN-320.
1382#
1383# The `wb' device provides support for various fast ethernet adapters
1384# based on the Winbond W89C840F chip. Note: this is not the same as
1385# the Winbond W89C940F, which is an NE2000 clone.
1386#
1387# The `xl' device provides support for the 3Com 3c900, 3c905 and
1388# 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1389# includes the integrated 3c905B-TX chips in certain Dell Optiplex and
1390# Dell Precision desktop machines and the integrated 3c905-TX chips
1391# in Dell Latitude laptop docking stations.
1392#
1393# The 'bktr' device is a PCI video capture device using the Brooktree
1394# bt848/bt848a/bt849a/bt878/bt879 chipset. When used with a TV Tuner it forms a
