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

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

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

1325 # on the RealTek 8129/8139 chipset. Note that the RealTek driver defaults

1329 # the MPX 5030/5038, which is either a RealTek in disguise or a RealTek

1334 # ethernet adapters based on the Adaptec AIC-6915 "starfire" controller.
1335 # This includes dual and quad port cards, as well as one 100baseFX card.

1352 # attach each one as a separate network interface.
