869# SCSI DEVICE CONFIGURATION
870
871# The SCSI subsystem consists of the `base' SCSI code, a number of
872# high-level SCSI device `type' drivers, and the low-level host-adapter
873# device drivers. The host adapters are listed in the ISA and PCI
874# device configuration sections below.
875#
876# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
877# that a given bus, target, and LUN always come on line as the same
878# device unit. In earlier versions the unit numbers were assigned
879# in the order that the devices were probed on the SCSI bus. This
880# means that if you removed a disk drive, you may have had to rewrite
881# your /etc/fstab file, and also that you had to be careful when adding
882# a new disk as it may have been probed earlier and moved your device
883# configuration around.
884
885# This old behavior is maintained as the default behavior. The unit
886# assignment begins with the first non-wired down unit for a device
887# type. For example, if you wire a disk as "da3" then the first
888# non-wired disk will be assigned da4.
889
890# The syntax for wiring down devices is:
891
892# device scbus0 at ahc0 # Single bus device
893# device scbus1 at ahc1 bus 0 # Single bus device
894# device scbus3 at ahc2 bus 0 # Twin bus device
895# device scbus2 at ahc2 bus 1 # Twin bus device
896# device da0 at scbus0 target 0 unit 0

1493# The flags takes the following meaning for apm0:
1494# 0x0020 Statclock is broken.

1498# Notes on the spigot:
1499# The video spigot is at 0xad6. This port address can not be changed.

1509# Notes on the Comtrol Rocketport driver:
1510#
1511# The exact values used for rp0 depend on how many boards you have
1512# in the system. The manufacturer's sample configs are listed as:
1513#
1514# Comtrol Rocketport ISA single card
1515# device rp0 at isa? port 0x280
1516#
1517# If instead you have two ISA cards, one installed at 0x100 and the
1518# second installed at 0x180, then you should add the following to
1519# your kernel configuration file:
1520#
1521# device rp0 at isa? port 0x100
1522# device rp1 at isa? port 0x180
1523#
1524# For 4 ISA cards, it might be something like this:
1525#
1526# device rp0 at isa? port 0x180
1527# device rp1 at isa? port 0x100
1528# device rp2 at isa? port 0x340
1529# device rp3 at isa? port 0x240
1530#
1531# And for PCI cards, you only need say:
1532#
1533# device rp
1534
1535# Notes on the Digiboard driver:
1536#
1537# The following flag values have special meanings:
1538# 0x01 - alternate layout of pins (dgb & dgm)
1539# 0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1540
1541# Notes on the Specialix SI/XIO driver:
1542# **This is NOT a Specialix supported Driver!**
1543# The host card is memory, not IO mapped.
1544# The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1545# The Rev 2 host cards use a 32K chunk, on a 32K boundary.
1546# The cards can use an IRQ of 11, 12 or 15.

1550# This is version 2.0.0, unsupported by Stallion.
1551# The stl driver has a secondary IO port hard coded at 0x280. You need
1552# to change src/i386/isa/stallion.c if you reconfigure this on the boards.
1553# The "flags" and "iosiz" settings on the stli driver depend on the board:
1554# EasyConnection 8/64 ISA: flags 23 iosiz 0x1000

2406# a KLD module.
2407# The STREAMS network emulation code can also be compiled statically or as a
2408# module. If loaded as a module, it must be loaded before the svr4 module
2409# (the /usr/sbin/svr4 script does this for you). If compiling statically,
2410# the `streams' pseudo-device must be configured into any kernel which also
2411# specifies COMPAT_SVR4. It is possible to have a statically-configured
2412# STREAMS device and a dynamically loadable svr4 emulator; the /usr/sbin/svr4
2413# script understands that it doesn't need to load the `streams' module under
2414# those circumstances.
2415# Caveat: At this time, `options KTRACE' is required for the svr4 emulator
2416# (whether static or dynamic).

2428# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).

2431# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
2432# Compaq are actually DPT controllers.
2433#
2434# See src/sys/dev/dpt for debugging and other subtle options.
2435# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
2436# instruments are enabled. The tools in
2437# /usr/sbin/dpt_* assume these to be enabled.
2438# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
2439# If you ant the driver to handle timeouts, enable
2440# this option. If your system is very busy, this
2441# option will create more trouble than solve.
2442# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
2443# wait when timing out with the above option.
2444# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
2445# DPT_LOST_IRQ When enabled, will try, once per second, to catch
2446# any interrupt that got lost. Seems to help in some
2447# DPT-firmware/Motherboard combinations. Minimal
2448# cost, great benefit.
2449# DPT_RESET_HBA Make "reset" actually reset the controller
2450# instead of fudging it. Only enable this if you
