28 # internal system tables by a formula defined in subr_param.c. Setting
29 # maxusers to 0 will cause the system to auto-size based on physical
35 # The `makeoptions' parameter allows variables to be passed to the
36 # generated Makefile in the build area.

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

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

877 # SCSI DEVICE CONFIGURATION
879 # The SCSI subsystem consists of the `base' SCSI code, a number of
880 # high-level SCSI device `type' drivers, and the low-level host-adapter
881 # device drivers. The host adapters are listed in the ISA and PCI
882 # device configuration sections below.
884 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
885 # that a given bus, target, and LUN always come on line as the same
886 # device unit. In earlier versions the unit numbers were assigned
887 # in the order that the devices were probed on the SCSI bus. This
888 # means that if you removed a disk drive, you may have had to rewrite
889 # your /etc/fstab file, and also that you had to be careful when adding
890 # a new disk as it may have been probed earlier and moved your device
891 # configuration around.
893 # This old behavior is maintained as the default behavior. The unit
894 # assignment begins with the first non-wired down unit for a device
895 # type. For example, if you wire a disk as "da3" then the first
896 # non-wired disk will be assigned da4.
898 # The syntax for wiring down devices is:
900 # device scbus0 at ahc0 # Single bus device
901 # device scbus1 at ahc1 bus 0 # Single bus device
902 # device scbus3 at ahc2 bus 0 # Twin bus device
903 # device scbus2 at ahc2 bus 1 # Twin bus device
904 # device da0 at scbus0 target 0 unit 0
905 # device da1 at scbus3 target 1
906 # device da2 at scbus2 target 3
907 # device sa1 at scbus1 target 6
910 # "units" (SCSI logical unit number) that are not specified are
911 # treated as if specified as LUN 0.

1772 # The 'pcn' device provides support for PCI fast ethernet adapters based
1773 # on the AMD Am79c97x chipsets, including the PCnet/FAST, PCnet/FAST+,
1774 # PCnet/PRO and PCnet/Home. These were previously handled by the lnc
1775 # driver (and still will be if you leave this driver out of the kernel).
1777 # Te 're' device provides support for PCI GigaBit ethernet adapters based
1778 # on the RealTek 8169 chipset. It also supports the 8139C+ and is the
1779 # preferred driver for that chip.
1781 # The 'rl' device provides support for PCI fast ethernet adapters based
1782 # on the RealTek 8129/8139 chipset. Note that the RealTek driver defaults
1783 # to using programmed I/O to do register accesses because memory mapped
1784 # mode seems to cause severe lockups on SMP hardware. This driver also
1785 # supports the Accton EN1207D `Cheetah' adapter, which uses a chip called
1786 # the MPX 5030/5038, which is either a RealTek in disguise or a RealTek
1787 # workalike. Note that the D-Link DFE-530TX+ uses the RealTek chipset
1788 # and is supported by this driver, not the 'vr' driver.
1790 # The 'sf' device provides support for Adaptec Duralink PCI fast
1791 # ethernet adapters based on the Adaptec AIC-6915 "starfire" controller.
1792 # This includes dual and quad port cards, as well as one 100baseFX card.
1793 # Most of these are 64-bit PCI devices, except for one single port
1794 # card which is 32-bit.
1796 # The 'ste' device provides support for adapters based on the Sundance
1797 # Technologies ST201 PCI fast ethernet controller. This includes the

1801 # Integrated Systems SiS 900 and SiS 7016 PCI fast ethernet controller
1804 # The 'sk' device provides support for the SysKonnect SK-984x series
1805 # PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842
1806 # single port cards (single mode and multimode fiber) and the
1807 # SK-9843 and SK-9844 dual port cards (also single mode and multimode).
1808 # The driver will autodetect the number of ports on the card and
1809 # attach each one as a separate network interface.
1811 # The 'ti' device provides support for PCI gigabit ethernet NICs based
1812 # on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1813 # Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.
1814 # Note that you will probably want to bump up NMBCLUSTERS a lot to use
1817 # The 'tl' device provides support for the Texas Instruments TNETE100
1818 # series 'ThunderLAN' cards and integrated ethernet controllers. This
1819 # includes several Compaq Netelligent 10/100 cards and the built-in
1820 # ethernet controllers in several Compaq Prosignia, Proliant and
1821 # Deskpro systems. It also supports several Olicom 10Mbps and 10/100
1824 # The `tx' device provides support for the SMC 9432 TX, BTX and FTX cards.
1826 # The `txp' device provides support for the 3Com 3cR990 "Typhoon"
1829 # The `vr' device provides support for various fast ethernet adapters
1830 # based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1831 # chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1832 # Technologies PN102TX, and the AOpen/Acer ALN-320.
1834 # The `vx' device provides support for the 3Com 3C590 and 3C595
1837 # The `wb' device provides support for various fast ethernet adapters
1838 # based on the Winbond W89C840F chip. Note: this is not the same as
1839 # the Winbond W89C940F, which is an NE2000 clone.
1841 # The `xl' device provides support for the 3Com 3c900, 3c905 and
1842 # 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1843 # includes the integrated 3c905B-TX chips in certain Dell Optiplex and
1844 # Dell Precision desktop machines and the integrated 3c905-TX chips
1845 # in Dell Latitude laptop docking stations.
1847 # The `meteor' device is a PCI video capture board. It can also have the
