276# MAXMEM specifies the amount of RAM on the machine; if this is not

554# This is a temporary driver that should someday be replaced by something

556# General Device 10 decoder, which means you have to fiddle with PCI
557# registers to map it in, even though it is otherwise treated here as
558# an ISA device. At the moment, the driver polls, although the device
559# is capable of generating interrupts. It largely undocumented.
560# The port location in the hint is where you WANT the device to be
561# mapped. 0x10a0 seems to be traditional. At the moment the jogdial

260# Options for `isa':
261#
262# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
263# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
264# This option breaks suspend/resume on some portables.
265#
266# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
267# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
268# Automatic EOI is documented not to work for for the slave with the
269# original i8259A, but it works for some clones and some integrated
270# versions.
271#
272# MAXMEM specifies the amount of RAM on the machine; if this is not
273# specified, FreeBSD will first read the amount of memory from the CMOS
274# RAM, so the amount of memory will initially be limited to 64MB or 16MB
275# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
276# then attempt to detect the installed amount of RAM. If this probe
277# fails to detect >64MB RAM you will have to use the MAXMEM option.
278# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
279# be 131072 (128 * 1024).
280#
281# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to
282# reset the CPU for reboot. This is needed on some systems with broken
283# keyboard controllers.

327# The Numeric Processing eXtension driver. In addition to this, you
328# may configure a math emulator (see above). If your machine has a
329# hardware FPU and the kernel configuration includes the npx device
330# *and* a math emulator compiled into the kernel, the hardware FPU
331# will be used, unless it is found to be broken or unless "flags" to
332# npx0 includes "0x08", which requests preference for the emulator.
333device npx
334
335#
336# `flags' for npx0:
337# 0x01 don't use the npx registers to optimize bcopy.
338# 0x02 don't use the npx registers to optimize bzero.
339# 0x04 don't use the npx registers to optimize copyin or copyout.
340# 0x08 use emulator even if hardware FPU is available.
341# The npx registers are normally used to optimize copying and zeroing when
342# all of the following conditions are satisfied:
343# I586_CPU is an option
344# the cpu is an i586 (perhaps not a Pentium)
345# the probe for npx0 succeeds
346# INT 16 exception handling works.
347# Then copying and zeroing using the npx registers is normally 30-100% faster.
348# The flags can be used to control cases where it doesn't work or is slower.
349# Setting them at boot time using userconfig works right (the optimizations
350# are not used until later in the bootstrap when npx0 is attached).
351# Flag 0x08 automatically disables the i586 optimized routines.

539# to access the spigot. This option is not secure because it allows users
540# direct access to the I/O page.
541# options SPIGOT_UNSECURE
542
543# Notes on the Specialix SI/XIO driver:
544# The host card is memory, not IO mapped.
545# The Rev 1 host cards use a 64K chunk, on a 32K boundary.

549# Notes on the Sony Programmable I/O controller
550# This is a temporary driver that should someday be replaced by something
551# that hooks into the ACPI layer. The device is hooked to the PIIX4's
552# General Device 10 decoder, which means you have to fiddle with PCI
553# registers to map it in, even though it is otherwise treated here as
554# an ISA device. At the moment, the driver polls, although the device
555# is capable of generating interrupts. It largely undocumented.
556# The port location in the hint is where you WANT the device to be
557# mapped. 0x10a0 seems to be traditional. At the moment the jogdial
558# is the only thing truly supported, but aparently a fair percentage
559# of the Vaio extra features are controlled by this device.
560
561# Notes on the Stallion stl and stli drivers:
562# See src/i386/isa/README.stl for complete instructions.
563# This is version 0.0.5alpha, unsupported by Stallion.
564# The stl driver has a secondary IO port hard coded at 0x280. You need
565# to change src/i386/isa/stallion.c if you reconfigure this on the boards.
566# The "flags" and "msize" settings on the stli driver depend on the board:
567# EasyConnection 8/64 ISA: flags 23 msize 0x1000
568# EasyConnection 8/64 EISA: flags 24 msize 0x10000
569# EasyConnection 8/64 MCA: flags 25 msize 0x1000
570# ONboard ISA: flags 4 msize 0x10000

576# Notes on the Digiboard PC/Xi and PC/Xe series driver
577#
578# The NDGBPORTS option specifies the number of ports controlled by the

880# script understands that it doesn't need to load the `streams' module under
881# those circumstances.
