161# BlueLightning CPU. It works only with Cyrix FPU, and this option
162# should not be used with Intel FPU.

164# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning

205# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
206# 1).
207#
208# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
209# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
210# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.

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
233# which indicates that the 15-16MB range is *definitely* not being

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

1040# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
1041# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1042# This option breaks suspend/resume on some portables.

1044# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
1045# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1046# Automatic EOI is documented not to work for for the slave with the

1048# versions.
1049#
1050# MAXMEM specifies the amount of RAM on the machine; if this is not
1051# specified, FreeBSD will first read the amount of memory from the CMOS
1052# RAM, so the amount of memory will initially be limited to 64MB or 16MB
1053# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
1054# then attempt to detect the installed amount of RAM. If this probe
1055# fails to detect >64MB RAM you will have to use the MAXMEM option.
1056# The amount is in kilobytes, so for a machine with 128MB of RAM, it would

1500# The flags takes the following meaning for apm0:
1501# 0x0020 Statclock is broken.

1516# Notes on the Comtrol Rocketport driver:
1517#
1518# The exact values used for rp0 depend on how many boards you have
1519# in the system. The manufacturer's sample configs are listed as:
1520#
1521# Comtrol Rocketport ISA single card
1522# device rp0 at isa? port 0x280
1523#
1524# If instead you have two ISA cards, one installed at 0x100 and the
1525# second installed at 0x180, then you should add the following to
1526# your kernel configuration file:
1527#
1528# device rp0 at isa? port 0x100
1529# device rp1 at isa? port 0x180
1530#
1531# For 4 ISA cards, it might be something like this:
1532#
1533# device rp0 at isa? port 0x180
1534# device rp1 at isa? port 0x100
1535# device rp2 at isa? port 0x340
1536# device rp3 at isa? port 0x240
1537#
1538# And for PCI cards, you only need say:
1539#
1540# device rp
1541
1542# Notes on the Digiboard driver:
1543#
1544# The following flag values have special meanings:
1545# 0x01 - alternate layout of pins (dgb & dgm)
1546# 0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1547
1548# Notes on the Specialix SI/XIO driver:
1549# **This is NOT a Specialix supported Driver!**
1550# The host card is memory, not IO mapped.
1551# The Rev 1 host cards use a 64K chunk, on a 32K boundary.

1553# The cards can use an IRQ of 11, 12 or 15.

1558# The stl driver has a secondary IO port hard coded at 0x280. You need

2417# The STREAMS network emulation code can also be compiled statically or as a

2419# (the /usr/sbin/svr4 script does this for you). If compiling statically,
2420# the `streams' pseudo-device must be configured into any kernel which also
2421# specifies COMPAT_SVR4. It is possible to have a statically-configured
2422# STREAMS device and a dynamically loadable svr4 emulator; the /usr/sbin/svr4
2423# script understands that it doesn't need to load the `streams' module under
2424# those circumstances.

2450# this option. If your system is very busy, this
2451# option will create more trouble than solve.
2452# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
2453# wait when timing out with the above option.
2454# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
2455# DPT_LOST_IRQ When enabled, will try, once per second, to catch
2456# any interrupt that got lost. Seems to help in some
