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 mandatory ``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

37 # The `makeoptions' parameter allows variables to be passed to the

44 # DEBUG happens to be magic.
45 # The following is equivalent to 'config -g KERNELNAME' and creates

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

1331 # on the RealTek 8169 chipset. It also supports the 8139C+ and is the
1332 # preferred driver for that chip.

1335 # on the RealTek 8129/8139 chipset. Note that the RealTek driver defaults
1336 # to using programmed I/O to do register accesses because memory mapped
1337 # mode seems to cause severe lockups on SMP hardware. This driver also
1338 # supports the Accton EN1207D `Cheetah' adapter, which uses a chip called
1339 # the MPX 5030/5038, which is either a RealTek in disguise or a RealTek
1340 # workalike. Note that the D-Link DFE-530TX+ uses the RealTek chipset
1341 # and is supported by this driver, not the 'vr' driver.

1344 # ethernet adapters based on the Adaptec AIC-6915 "starfire" controller.

1347 # card which is 32-bit.

1358 # PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1359 # single port cards (single mode and multimode fiber) and the
1360 # SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1361 # The driver will autodetect the number of ports on the card and
1362 # attach each one as a separate network interface.
1364 # The 'ti' device provides support for PCI gigabit ethernet NICs based
1365 # on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1366 # Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.

1370 # The 'tl' device provides support for the Texas Instruments TNETE100
1371 # series 'ThunderLAN' cards and integrated ethernet controllers. This
1372 # includes several Compaq Netelligent 10/100 cards and the built-in
1373 # ethernet controllers in several Compaq Prosignia, Proliant and

1388 # based on the Winbond W89C840F chip. Note: this is not the same as
1389 # the Winbond W89C940F, which is an NE2000 clone.
1391 # The `xl' device provides support for the 3Com 3c900, 3c905 and
