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

48 # but that isn't normally necessary as the debug symbols are not loaded
49 # by the kernel and are not useful there anyway.

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

1334 # the MPX 5030/5038, which is either a RealTek in disguise or a RealTek

1355 # SK-9843 and SK-9844 dual port cards (also single mode and multimode).

1357 # attach each one as a separate network interface.
1359 # The 'ti' device provides support for PCI gigabit ethernet NICs based
1360 # on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the

1365 # The 'tl' device provides support for the Texas Instruments TNETE100
1366 # series 'ThunderLAN' cards and integrated ethernet controllers. This
1367 # includes several Compaq Netelligent 10/100 cards and the built-in

1380 # Technologies PN102TX, and the AOpen/Acer ALN-320.
1382 # The `wb' device provides support for various fast ethernet adapters
1383 # based on the Winbond W89C840F chip. Note: this is not the same as
1384 # the Winbond W89C940F, which is an NE2000 clone.
1386 # The `xl' device provides support for the 3Com 3c900, 3c905 and
