15 # These directives are mandatory. The machine directive specifies the
16 # platform and the machine_arch directive specifies the cpu architecture.
23 # This is the ``identification'' of the kernel. Usually this should
24 # be the same as the name of your kernel.
29 # The `maxusers' parameter controls the static sizing of a number of
30 # internal system tables by a formula defined in subr_param.c. Setting
31 # maxusers to 0 will cause the system to auto-size based on physical
37 # The `makeoptions' parameter allows variables to be passed to the
38 # generated Makefile in the build area.
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).
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

582 # SCSI DEVICE CONFIGURATION
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.
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.
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.
603 # The syntax for wiring down devices is:
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
615 # "units" (SCSI logical unit number) that are not specified are
616 # treated as if specified as LUN 0.
618 # All SCSI devices allocate as many units as are required.

1328 # on the RealTek 8169 chipset. It also supports the 8139C+ and is the
1329 # preferred driver for that chip.
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
1333 # to using programmed I/O to do register accesses because memory mapped
1334 # mode seems to cause severe lockups on SMP hardware. This driver also
1335 # supports the Accton EN1207D `Cheetah' adapter, which uses a chip called
1336 # the MPX 5030/5038, which is either a RealTek in disguise or a RealTek
1337 # workalike. Note that the D-Link DFE-530TX+ uses the RealTek chipset
1338 # and is supported by this driver, not the 'vr' driver.

1341 # ethernet adapters based on the Adaptec AIC-6915 "starfire" controller.

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.
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

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

1385 # based on the Winbond W89C840F chip. Note: this is not the same as
1386 # the Winbond W89C940F, which is an NE2000 clone.
1388 # The `xl' device provides support for the 3Com 3c900, 3c905 and
