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

41 # after most other flags. Here we use it to inhibit use of non-optimal

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

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

1318 # to using programmed I/O to do register accesses because memory mapped
1319 # mode seems to cause severe lockups on SMP hardware. This driver also
1320 # supports the Accton EN1207D `Cheetah' adapter, which uses a chip called
1321 # the MPX 5030/5038, which is either a RealTek in disguise or a RealTek
1322 # workalike. Note that the D-Link DFE-530TX+ uses the RealTek chipset
1323 # and is supported by this driver, not the 'vr' driver.
1325 # The 'sf' device provides support for Adaptec Duralink PCI fast
1326 # ethernet adapters based on the Adaptec AIC-6915 "starfire" controller.
1327 # This includes dual and quad port cards, as well as one 100baseFX card.

1329 # card which is 32-bit.

1332 # Technologies ST201 PCI fast ethernet controller. This includes the

1339 # The 'sk' device provides support for the SysKonnect SK-984x series
1340 # PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1341 # single port cards (single mode and multimode fiber) and the
1342 # SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1343 # The driver will autodetect the number of ports on the card and
1344 # attach each one as a separate network interface.
1346 # The 'ti' device provides support for PCI gigabit ethernet NICs based
1347 # on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the

1352 # The 'tl' device provides support for the Texas Instruments TNETE100
1353 # series 'ThunderLAN' cards and integrated ethernet controllers. This
1354 # includes several Compaq Netelligent 10/100 cards and the built-in
