517# The `arcnet' pseudo-device provides generic code to support Arcnet.

522# The `bpf' pseudo-device enables the Berkeley Packet Filter. Be

873
874# SCSI DEVICE CONFIGURATION
875
876# The SCSI subsystem consists of the `base' SCSI code, a number of
877# high-level SCSI device `type' drivers, and the low-level host-adapter
878# device drivers. The host adapters are listed in the ISA and PCI
879# device configuration sections below.
880#
881# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
882# that a given bus, target, and LUN always come on line as the same
883# device unit. In earlier versions the unit numbers were assigned
884# in the order that the devices were probed on the SCSI bus. This
885# means that if you removed a disk drive, you may have had to rewrite
886# your /etc/fstab file, and also that you had to be careful when adding
887# a new disk as it may have been probed earlier and moved your device
888# configuration around.
889
890# This old behavior is maintained as the default behavior. The unit
891# assignment begins with the first non-wired down unit for a device
892# type. For example, if you wire a disk as "da3" then the first
893# non-wired disk will be assigned da4.
894
895# The syntax for wiring down devices is:
896
897# device scbus0 at ahc0 # Single bus device
898# device scbus1 at ahc1 bus 0 # Single bus device
899# device scbus3 at ahc2 bus 0 # Twin bus device
900# device scbus2 at ahc2 bus 1 # Twin bus device
901# device da0 at scbus0 target 0 unit 0
902# device da1 at scbus3 target 1
903# device da2 at scbus2 target 3
904# device sa1 at scbus1 target 6

1041#
1042# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
1043# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1044# This option breaks suspend/resume on some portables.
1045#
1046# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
1047# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1048# Automatic EOI is documented not to work for for the slave with the
1049# original i8259A, but it works for some clones and some integrated
1050# versions.
1051#
1052# MAXMEM specifies the amount of RAM on the machine; if this is not
1053# specified, FreeBSD will first read the amount of memory from the CMOS
1054# RAM, so the amount of memory will initially be limited to 64MB or 16MB
1055# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
1056# then attempt to detect the installed amount of RAM. If this probe
1057# fails to detect >64MB RAM you will have to use the MAXMEM option.
1058# The amount is in kilobytes, so for a machine with 128MB of RAM, it would

1840# 10/100 adapters.
1841#
1842# The `vr' device provides support for various fast ethernet adapters
1843# based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II'
1844# chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1845# Technologies PN102TX, and the AOpen/Acer ALN-320.
1846#
1847# The `vx' device provides support for the 3Com 3C590 and 3C595
1848# early support
1849#
1850# The `wb' device provides support for various fast ethernet adapters
1851# based on the Winbond W89C840F chip. Note: this is not the same as
1852# the Winbond W89C940F, which is an NE2000 clone.

1854# The `xl' device provides support for the 3Com 3c900, 3c905 and
1855# 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1856# includes the integrated 3c905B-TX chips in certain Dell Optiplex and
1857# Dell Precision desktop machines and the integrated 3c905-TX chips
1858# in Dell Latitude laptop docking stations.

1860# The `fpa' device provides support for the Digital DEFPA PCI FDDI
1861# adapter. pseudo-device fddi is also needed.

1863# The `meteor' device is a PCI video capture board. It can also have the
1864# following options:
1865# options METEOR_ALLOC_PAGES=xxx preallocate kernel pages for data entry
1866# figure (ROWS*COLUMN*BYTES_PER_PIXEL*FRAME+PAGE_SIZE-1)/PAGE_SIZE
1867# options METEOR_DEALLOC_PAGES remove all allocated pages on close(2)

1874# The 'bktr' device is a PCI video capture device using the Brooktree
1875# bt848/bt848a/bt849a/bt878/bt879 chipset. When used with a TV Tuner it forms a
1876# TV card, eg Miro PC/TV, Hauppauge WinCast/TV WinTV, VideoLogic Captivator,
