857# SCSI DEVICE CONFIGURATION
858
859# The SCSI subsystem consists of the `base' SCSI code, a number of
860# high-level SCSI device `type' drivers, and the low-level host-adapter
861# device drivers. The host adapters are listed in the ISA and PCI
862# device configuration sections below.
863#
864# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
865# that a given bus, target, and LUN always come on line as the same
866# device unit. In earlier versions the unit numbers were assigned
867# in the order that the devices were probed on the SCSI bus. This
868# means that if you removed a disk drive, you may have had to rewrite
869# your /etc/fstab file, and also that you had to be careful when adding
870# a new disk as it may have been probed earlier and moved your device
871# configuration around.
872
873# This old behavior is maintained as the default behavior. The unit
874# assignment begins with the first non-wired down unit for a device
875# type. For example, if you wire a disk as "da3" then the first
876# non-wired disk will be assigned da4.
877
878# The syntax for wiring down devices is:
879
880# device scbus0 at ahc0 # Single bus device
881# device scbus1 at ahc1 bus 0 # Single bus device
882# device scbus3 at ahc2 bus 0 # Twin bus device
883# device scbus2 at ahc2 bus 1 # Twin bus device
884# device da0 at scbus0 target 0 unit 0
885# device da1 at scbus3 target 1
886# device da2 at scbus2 target 3
887# device sa1 at scbus1 target 6

1610# Notes on the Comtrol Rocketport driver:
1611#
1612# The exact values used for rp0 depend on how many boards you have

1614#
1615# Comtrol Rocketport ISA single card
1616# device rp0 at isa? port 0x280
1617#
1618# If instead you have two ISA cards, one installed at 0x100 and the
1619# second installed at 0x180, then you should add the following to
1620# your kernel configuration file:
1621#
1622# device rp0 at isa? port 0x100
1623# device rp1 at isa? port 0x180

1628# device rp1 at isa? port 0x100
1629# device rp2 at isa? port 0x340
1630# device rp3 at isa? port 0x240
1631#
1632# And for PCI cards, you only need say:
1633#
1634# device rp
1635
1636# Notes on the Digiboard driver:
1637#
1638# The following flag values have special meanings:
1639# 0x01 - alternate layout of pins (dgb & dgm)
1640# 0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1641
1642# Notes on the Specialix SI/XIO driver:
1643# **This is NOT a Specialix supported Driver!**
1644# The host card is memory, not IO mapped.
1645# The Rev 1 host cards use a 64K chunk, on a 32K boundary.

1647# The cards can use an IRQ of 11, 12 or 15.

1652# The stl driver has a secondary IO port hard coded at 0x280. You need

1899# The `xl' device provides support for the 3Com 3c900, 3c905 and
1900# 3c905B (Fast) Etherlink XL cards and integrated controllers. This
1901# includes the integrated 3c905B-TX chips in certain Dell Optiplex and
1902# Dell Precision desktop machines and the integrated 3c905-TX chips
1903# in Dell Latitude laptop docking stations.

1905# The `fpa' device provides support for the Digital DEFPA PCI FDDI
1906# adapter. pseudo-device fddi is also needed.
