227# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY

230# and should be included for any non-Pentium CPU that defines it.
231#
232# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors

871# SCSI DEVICE CONFIGURATION
872
873# The SCSI subsystem consists of the `base' SCSI code, a number of
874# high-level SCSI device `type' drivers, and the low-level host-adapter
875# device drivers. The host adapters are listed in the ISA and PCI
876# device configuration sections below.
877#
878# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
879# that a given bus, target, and LUN always come on line as the same
880# device unit. In earlier versions the unit numbers were assigned
881# in the order that the devices were probed on the SCSI bus. This
882# means that if you removed a disk drive, you may have had to rewrite
883# your /etc/fstab file, and also that you had to be careful when adding
884# a new disk as it may have been probed earlier and moved your device
885# configuration around.
886
887# This old behavior is maintained as the default behavior. The unit
888# assignment begins with the first non-wired down unit for a device
889# type. For example, if you wire a disk as "da3" then the first
890# non-wired disk will be assigned da4.
891
892# The syntax for wiring down devices is:
893
894# device scbus0 at ahc0 # Single bus device
895# device scbus1 at ahc1 bus 0 # Single bus device
896# device scbus3 at ahc2 bus 0 # Twin bus device
897# device scbus2 at ahc2 bus 1 # Twin bus device
898# device da0 at scbus0 target 0 unit 0
899# device da1 at scbus3 target 1
900# device da2 at scbus2 target 3
901# device sa1 at scbus1 target 6
902# device cd
903
904# "units" (SCSI logical unit number) that are not specified are

1501# The video spigot is at 0xad6. This port address can not be changed.

1511# Notes on the Comtrol Rocketport driver:
1512#
1513# The exact values used for rp0 depend on how many boards you have
1514# in the system. The manufacturer's sample configs are listed as:
1515#
1516# Comtrol Rocketport ISA single card
1517# device rp0 at isa? port 0x280
1518#
1519# If instead you have two ISA cards, one installed at 0x100 and the
1520# second installed at 0x180, then you should add the following to
1521# your kernel configuration file:
1522#
1523# device rp0 at isa? port 0x100
1524# device rp1 at isa? port 0x180
1525#
1526# For 4 ISA cards, it might be something like this:
1527#
1528# device rp0 at isa? port 0x180
1529# device rp1 at isa? port 0x100
1530# device rp2 at isa? port 0x340
1531# device rp3 at isa? port 0x240
1532#
1533# And for PCI cards, you only need say:
1534#
1535# device rp
1536
1537# Notes on the Digiboard driver:
1538#
1539# The following flag values have special meanings:
1540# 0x01 - alternate layout of pins (dgb & dgm)
1541# 0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1542
1543# Notes on the Specialix SI/XIO driver:
1544# **This is NOT a Specialix supported Driver!**
1545# The host card is memory, not IO mapped.
1546# The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1547# The Rev 2 host cards use a 32K chunk, on a 32K boundary.
1548# The cards can use an IRQ of 11, 12 or 15.

1553# The stl driver has a secondary IO port hard coded at 0x280. You need
1554# to change src/i386/isa/stallion.c if you reconfigure this on the boards.
1555# The "flags" and "iosiz" settings on the stli driver depend on the board:
1556# EasyConnection 8/64 ISA: flags 23 iosiz 0x1000

2408# a KLD module.
2409# The STREAMS network emulation code can also be compiled statically or as a
2410# module. If loaded as a module, it must be loaded before the svr4 module
2411# (the /usr/sbin/svr4 script does this for you). If compiling statically,
2412# the `streams' pseudo-device must be configured into any kernel which also
2413# specifies COMPAT_SVR4. It is possible to have a statically-configured
2414# STREAMS device and a dynamically loadable svr4 emulator; the /usr/sbin/svr4
2415# script understands that it doesn't need to load the `streams' module under
2416# those circumstances.
2417# Caveat: At this time, `options KTRACE' is required for the svr4 emulator
2418# (whether static or dynamic).

2433# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and

2441# If you ant the driver to handle timeouts, enable
2442# this option. If your system is very busy, this
2443# option will create more trouble than solve.
2444# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
2445# wait when timing out with the above option.
2446# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
2447# DPT_LOST_IRQ When enabled, will try, once per second, to catch
2448# any interrupt that got lost. Seems to help in some
2449# DPT-firmware/Motherboard combinations. Minimal
2450# cost, great benefit.
