# NB: You probably don't want to try running a kernel built from this
# file.  Instead, you should start from GENERIC, and add options from
# this file as required.
#

#
# This directive is mandatory; it defines the architecture to be
# configured for; in this case, the 386 family.  You must also specify
# at least one CPU (the one you intend to run on); deleting the
# specification for CPUs you don't need to use may make parts of the
# system run faster
#
machine		"i386"
cpu		"I386_CPU"
cpu		"I486_CPU"
cpu		"I586_CPU"		# aka Pentium(tm)

#
# This is the ``identification'' of the kernel.  Usually this should
# be the same as the name of your kernel.
#
ident		LINT

#
# The `maxusers' parameter controls the static sizing of a number of
# internal system tables by a complicated formula defined in param.c.
#
maxusers	10

#
# Under some circumstances it is necessary to make the default max
# number of processes per user and open files per user more than the
# defaults on bootup.  (an example is a large news server in which
# the uid, news, can sometimes need > 100 simultaneous processes running,
# or perhaps a user using lots of windows under X).
options		CHILD_MAX=128
options		OPEN_MAX=128

#
# A math emulator is mandatory if you wish to run on hardware which
# does not have a floating-point processor.  Pick either the original,
# bogus (but freely-distributable) math emulator, or a much more
# fully-featured but GPL-licensed emulator taken from Linux.
#
options		MATH_EMULATE		#Support for x87 emulation
# Don't enable both of these in a real config.
options		GPL_MATH_EMULATE	#Support for x87 emualtion via
					#new math emulator

#
# This directive defines a number of things:
#  - The compiled kernel is to be called `kernel'
#  - The root filesystem might be on partition wd0a
#  - Crash dumps will be written to wd0b, if possible.  Specifying the
#    dump device here is not recommended.  Use dumpon(8).

# NB: The LFS, PORTAL, and UNION filesystems are known to be buggy,
# and WILL panic your system if you attempt to do anything with them.
# They are included here as an incentive for some enterprising soul to
# sit down and fix them.

# SCSI DEVICES

# SCSI DEVICE CONFIGURATION

# The SCSI subsystem consists of the `base' SCSI code, a number of
# high-level SCSI device `type' drivers, and the low-level host-adapter
# device drivers.  The host adapters are listed in the ISA and PCI
# device configuration sections below.
#
# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
# that a given bus, target, and LUN always come on line as the same
# device unit.  In earlier versions the unit numbers were assigned
# in the order that the devices were probed on the SCSI bus.  This
# means that if you removed a disk drive, you may have had to rewrite
# your /etc/fstab file, and also that you had to be careful when adding
# a new disk as it may have been probed earlier and moved your device
# configuration around.

# This old behavior is maintained as the default behavior.  The unit
# assignment begins with the first non-wired down unit for a device
# type.  For example, if you wire a disk as "sd3" then the first
# non-wired disk will be assigned sd4.

# The syntax for wiring down devices is:

# controller	scbus0 at ahc0		# Single bus device
# controller	scbus1 at ahc1 bus 0	# Single bus device
# controller	scbus3 at ahc2 bus 0	# Twin bus device
# controller	scbus2 at ahc2 bus 1	# Twin bus device
# disk 		sd0 at scbus0 target 0 unit 0
# disk		sd1 at scbus3 target 1
# disk		sd2 at scbus2 target 3
# tape		st1 at scbus1 target 6
# device	cd0 at scbus?

# "units" (SCSI logical unit number) that are not specified are
# treated as if specified as LUN 0.

# All SCSI devices allocate as many units as are required.

# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI
# configuration and doesn't have to be explicitly configured.

controller	scbus0	#base SCSI code
device		ch0	#SCSI media changers
device		sd0	#SCSI disks
device		st0	#SCSI tapes
device		cd0	#SCSI CD-ROMs
device		od0	#SCSI optical disk

# The previous devices (ch, sd, st, cd) are recognized by config.
# config doesn't (and shouldn't) know about these newer ones,
# so we have to specify that they are on a SCSI bus with the "at scbus?"
# clause.

device worm0 at scbus?	# SCSI worm
device pt0 at scbus?	# SCSI processor type
device sctarg0 at scbus? # SCSI target

# SCSI OPTIONS:

# SCSIDEBUG: When defined enables debugging macros
# NO_SCSI_SENSE: When defined disables sense descriptions (about 4k)
# SCSI_REPORT_GEOMETRY: Always report disk geometry at boot up instead
#                       of only when booting verbosely.

# HARDWARE DEVICE CONFIGURATION

# ISA and EISA devices:
# Currently there is no separate support for EISA.  There should be.
# Micro Channel is not supported at all.

#
# Mandatory ISA devices: isa, sc or vt, npx
#
controller	isa0

#
# Options for `isa':
#
# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
# interrupt controller.  This saves about 1.25 usec for each interrupt.
# No problems are known to be caused by this option.
#
# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
# interrupt controller.  This saves about 1.25 usec for each interrupt.
# Automatic EOI is documented not to work for for the slave with the
# original i8259A, but it works for some clones and some integrated
# versions.
#
# BOUNCE_BUFFERS provides support for ISA DMA on machines with more
# than 16 megabytes of memory.  It doesn't hurt on other machines.
# Some broken EISA and VLB hardware may need this, too.
#
# DUMMY_NOPS disables extra delays for some bus operations.  The delays
# are mostly for older systems and aren't used consistently.  Probably
# works OK on most EISA bus machines.
#
# TUNE_1542 enables the automatic ISA bus speed selection for the
# Adaptec 1542 boards. Does not work for all boards, use it with caution.
#
# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to
# reset the CPU for reboot.  This is needed on some systems with broken

# The flags fields are used to enable the multi-sector I/O and
# the 32BIT I/O modes.  The flags may be used in either the controller
# definition or in the individual disk definitions.  The controller
# definition is supported for the boot configuration stuff.
#
# Each drive has a 16 bit flags value defined:
#	The low 8 bits are the maximum value for the multi-sector I/O,
#	where 0xff defaults to the maximum that the drive can handle.
#	The high bit of the 16 bit flags (0x8000) allows probing for
#	32 bit transfers.
#
# The flags field for the drives can be specified in the controller
# specification with the low 16 bits for drive 0, and the high 16 bits
# for drive 1.
# e.g.:
#controller	wdc0	at isa? port "IO_WD1" bio irq 14 flags 0x00ff8004 vector wdintr
#
# specifies that drive 0 will be allowed to probe for 32 bit transfers and

#
# Notes on the spigot:
#  The video spigot is at 0xad6.  This port address can not be changed.
#  The irq values may only be 10, 11, or 15
#  I/O memory is an 8kb region.  Possible values are:
#    0a0000, 0a2000, ..., 0fffff, f00000, f02000, ..., ffffff
#    The start address must be on an even boundary.
#  Add the following option if you want to allow non-root users to be able
#  to access the spigot.  This option is not secure because it allows users
#  direct access to the I/O page.
#  	options SPIGOT_UNSECURE
#

# Notes on the Digiboard driver:
#
# The following flag values have special meanings:
#	0x01 - alternate layout of pins
#	0x02 - use the windowed PC/Xe in 64K mode

# Notes on the Specialix SI/XIO driver:
#  **This is NOT a Specialix supported Driver!**
#  The host card is memory, not IO mapped.
#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
#  The cards can use an IRQ of 11, 12 or 15.
