158# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
159# BlueLightning CPU. It works only with Cyrix FPU, and this option
160# should not be used with Intel FPU.
161#
162# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
163# CPU if CPU supports it. The default is double-clock mode on
164# BlueLightning CPU box.
165#
166# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
167#
168# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
169# mapped mode. Default is 2-way set associative mode.

172# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
173# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)

179# CPU_DISABLE_SSE disables SSE/MMX2 instructions support.
180#
181# CPU_FASTER_5X86_FPU enables faster FPU exception handler.

197# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
198# 1).
199#
200# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
201# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
202# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
203#
204# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).

210# K5/K6/K6-2 cpus.

212# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
213# flush at hold state.
214#
215# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs

217# Cyrix 6x86 whose revision < 2.7 (NOTE 2).

219# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
220# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
221# executed. This option is only needed if I586_CPU is also defined,
222# and should be included for any non-Pentium CPU that defines it.
223#

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

1612# Notes on the Comtrol Rocketport driver:
1613#
1614# The exact values used for rp0 depend on how many boards you have
1615# in the system. The manufacturer's sample configs are listed as:
1616#
1617# Comtrol Rocketport ISA single card
1618# device rp0 at isa? port 0x280
1619#
1620# If instead you have two ISA cards, one installed at 0x100 and the
1621# second installed at 0x180, then you should add the following to
1622# your kernel configuration file:
1623#
1624# device rp0 at isa? port 0x100
1625# device rp1 at isa? port 0x180
1626#
1627# For 4 ISA cards, it might be something like this:

1629# device rp0 at isa? port 0x180
1630# device rp1 at isa? port 0x100
1631# device rp2 at isa? port 0x340
1632# device rp3 at isa? port 0x240
1633#
1634# And for PCI cards, you only need say:
1635#
1636# device rp
1637
1638# Notes on the Digiboard driver:
1639#
1640# The following flag values have special meanings:
1641# 0x01 - alternate layout of pins (dgb & dgm)
1642# 0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1643
1644# Notes on the Specialix SI/XIO driver:
1645# **This is NOT a Specialix supported Driver!**
1646# The host card is memory, not IO mapped.
1647# The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1648# The Rev 2 host cards use a 32K chunk, on a 32K boundary.
1649# The cards can use an IRQ of 11, 12 or 15.

1651# Notes on the Stallion stl and stli drivers:
1652# See src/i386/isa/README.stl for complete instructions.
1653# This is version 2.0.0, unsupported by Stallion.
1654# The stl driver has a secondary IO port hard coded at 0x280. You need
1655# to change src/i386/isa/stallion.c if you reconfigure this on the boards.
1656# The "flags" and "iosiz" settings on the stli driver depend on the board:
1657# EasyConnection 8/64 ISA: flags 23 iosiz 0x1000
