# You may now use double quotes around pathnames, in case
# your pathname includes spaces.
#=======================================================================
# PLUGIN_CTRL:
# Controls the presence of optional device plugins. These plugins are loaded
# directly with this option and some of them install a config option that is
# only available when the plugin device is loaded. The value "1" means to load
# the plugin and "0" will unload it (if loaded before).
#
# These plugins will be loaded by default (if present): 'biosdev', 'extfpuirq',
# 'gameport', 'iodebug','parallel', 'serial', 'speaker' and 'unmapped'.
#
# These plugins are also supported, but they are usually loaded directly with
# their bochsrc option: 'e1000', 'es1370', 'ne2k', 'pcidev', 'pcipnic', 'sb16',
# 'usb_ehci', 'usb_ohci', 'usb_uhci', 'usb_xhci' and 'voodoo'.
#=======================================================================
#plugin_ctrl: unmapped=0, e1000=1 # unload 'unmapped' and load 'e1000'
#=======================================================================
# CONFIG_INTERFACE
#
# The configuration interface is a series of menus or dialog boxes that
# allows you to change all the settings that control Bochs's behavior.
# Depending on the platform there are up to 3 choices of configuration
# interface: a text mode version called "textconfig" and two graphical versions
# called "win32config" and "wx". The text mode version uses stdin/stdout and
# is always compiled in, unless Bochs is compiled for wx only. The choice
# "win32config" is only available on win32 and it is the default there.
# The choice "wx" is only available when you use "--with-wx" on the configure
# command. If you do not write a config_interface line, Bochs will
# choose a default for you.
#
# NOTE: if you use the "wx" configuration interface, you must also use
# the "wx" display library.
#=======================================================================
#config_interface: textconfig
#config_interface: win32config
#config_interface: wx
#=======================================================================
# DISPLAY_LIBRARY
#
# The display library is the code that displays the Bochs VGA screen. Bochs
# has a selection of about 10 different display library implementations for
# different platforms. If you run configure with multiple --with-* options,
# the display_library command lets you choose which one you want to run with.
# If you do not write a display_library line, Bochs will choose a default for
# you.
#
# The choices are:
# x use X windows interface, cross platform
# win32 use native win32 libraries
# carbon use Carbon library (for MacOS X)
# macintosh use MacOS pre-10
# amigaos use native AmigaOS libraries
# sdl use SDL 1.2.x library, cross platform
# sdl2 use SDL 2.x library, cross platform
# svga use SVGALIB library for Linux, allows graphics without X11
# term text only, uses curses/ncurses library, cross platform
# rfb provides an interface to AT&T's VNC viewer, cross platform
# vncsrv use LibVNCServer for extended RFB(VNC) support
# wx use wxWidgets library, cross platform
# nogui no display at all
#
# NOTE: if you use the "wx" configuration interface, you must also use
# the "wx" display library.
#
# Specific options:
# Some display libraries now support specific options to control their
# behaviour. These options are supported by more than one display library:
#
# "gui_debug" - use GTK debugger gui (sdl, sdl2, x) / Win32 debugger gui (sdl,
# sdl2, win32)
# "hideIPS" - disable IPS output in status bar (rfb, sdl, sdl2, vncsrv,
# win32, wx, x)
# "nokeyrepeat" - turn off host keyboard repeat (sdl, sdl2, win32, x)
# "timeout" - time (in seconds) to wait for client (rfb, vncsrv)
#
# See the examples below for other currently supported options.
#=======================================================================
#display_library: amigaos
#display_library: carbon
#display_library: macintosh
#display_library: nogui
#display_library: rfb
#display_library: sdl, options="fullscreen" # startup in fullscreen mode
#display_library: sdl2, options="fullscreen" # startup in fullscreen mode
#display_library: term
#display_library: vncsrv
# "traphotkeys" - system hotkeys not handled by host OS, but sent to guest
# (win32 in mouse capture and fullscreen mode: alt-tab, win,
# alt-space, alt-esc, ctrl-esc)
#display_library: win32, options="traphotkeys"
#display_library: wx
#display_library: x
#=======================================================================
# CPU:
# This defines cpu-related parameters inside Bochs:
#
# MODEL:
# Selects CPU configuration to emulate from pre-defined list of all
# supported configurations. When this option is used and the value
# is different from 'bx_generic', the parameters of the CPUID option
# have no effect anymore.
#
# CPU configurations that can be selected:

# COUNT:
# Set the number of processors:cores per processor:threads per core when
# Bochs is compiled for SMP emulation. Bochs currently supports up to
# 14 threads (legacy APIC) or 254 threads (xAPIC or higher) running
# simultaniosly. If Bochs is compiled without SMP support, it won't accept
# values different from 1.
#
# QUANTUM:
# Maximum amount of instructions allowed to execute by processor before
# returning control to another cpu. This option exists only in Bochs
# binary compiled with SMP support.
#
# RESET_ON_TRIPLE_FAULT:
# Reset the CPU when triple fault occur (highly recommended) rather than
# PANIC. Remember that if you trying to continue after triple fault the
# simulation will be completely bogus !
#
# CPUID_LIMIT_WINNT:
# Determine whether to limit maximum CPUID function to 2. This mode is
# required to workaround WinNT installation and boot issues.
#
# MSRS:
# Define path to user CPU Model Specific Registers (MSRs) specification.
# See example in msrs.def.
#
# IGNORE_BAD_MSRS:
# Ignore MSR references that Bochs does not understand; print a warning
# message instead of generating #GP exception. This option is enabled
# by default but will not be available if configurable MSRs are enabled.
#
# MWAIT_IS_NOP:
# When this option is enabled MWAIT will not put the CPU into a sleep state.
# This option exists only if Bochs compiled with --enable-monitor-mwait.
#
# IPS:
# Emulated Instructions Per Second. This is the number of IPS that bochs
# is capable of running on your machine. You can recompile Bochs with
# --enable-show-ips option enabled, to find your host's capability.
# Measured IPS value will then be logged into your log file or shown
# in the status bar (if supported by the gui).
#
# IPS is used to calibrate many time-dependent events within the bochs
# simulation. For example, changing IPS affects the frequency of VGA
# updates, the duration of time before a key starts to autorepeat, and
# the measurement of BogoMips and other benchmarks.
#
# Examples:
#
# Bochs Machine/Compiler Mips

# ROMIMAGE:
# The ROM BIOS controls what the PC does when it first powers on.
# Normally, you can use a precompiled BIOS in the source or binary
# distribution called BIOS-bochs-latest. The default ROM BIOS is usually loaded
# starting at address 0xfffe0000, and it is exactly 128k long. The legacy
# version of the Bochs BIOS is usually loaded starting at address 0xffff0000,
# and it is exactly 64k long.
# You can use the environment variable $BXSHARE to specify the location
# of the BIOS.
# The usage of external large BIOS images (up to 512k) at memory top is
# now supported, but we still recommend to use the BIOS distributed with Bochs.
# The start address is optional, since it can be calculated from image size.
# The Bochs BIOS currently supports only the option "fastboot" to skip the
# boot menu delay.

# VGA:
# This defines parameters related to the VGA display
#
# EXTENSION
# Here you can specify the display extension to be used. With the value
# 'none' you can use standard VGA with no extension. Other supported
# values are 'vbe' for Bochs VBE, 'cirrus' for Cirrus SVGA support and
# 'voodoo' for Voodoo Graphics support (see 'voodoo' option).
#
# UPDATE_FREQ
# This parameter specifies the number of display updates per second.
# The VGA update timer by default uses the realtime engine with a value
# of 5. This parameter can be changed at runtime.
#
# REALTIME
# If set to 1 (default), the VGA timer is based on realtime, otherwise it
# is driven by the cpu and depends on the ips setting. If the host is slow
# (low ips, update_freq) and the guest uses HLT appropriately, setting this
# to 0 and "clock: sync=none" may improve the responsiveness of the guest
# GUI when the guest is otherwise idle.
#
# Examples:
# vga: extension=cirrus, update_freq=10
#=======================================================================
#vga: extension=vbe, update_freq=5, realtime=1
#=======================================================================
# VOODOO:
# This defines the Voodoo Graphics emulation (experimental). Currently
# supported models are 'voodoo1', 'voodoo2', 'banshee' and 'voodoo3'. The
# Voodoo2 support is not yet complete, but almost usable. The Banshee and
# Voodoo3 support is under construction, but basically usable. The 2D/3D cards
# require an external VGA BIOS the vga extension option to be set to 'voodoo'.
# If the i440BX PCI chipset is selected, they can be assigned to AGP (slot #5).
# The gui screen update timing for all models is controlled by the related 'vga'
# options.
#
# Examples:
# voodoo: enabled=1, model=voodoo2
#=======================================================================
#voodoo: enabled=1, model=voodoo1
#=======================================================================
# KEYBOARD:
# This defines parameters related to the emulated keyboard
#
# TYPE:
# Type of keyboard return by a "identify keyboard" command to the
# keyboard controller. It must be one of "xt", "at" or "mf".
# Defaults to "mf". It should be ok for almost everybody. A known
# exception is french macs, that do have a "at"-like keyboard.
#
# SERIAL_DELAY:
# Approximate time in microseconds that it takes one character to
# be transferred from the keyboard to controller over the serial path.
#
# PASTE_DELAY:
# Approximate time in microseconds between attempts to paste
# characters to the keyboard controller. This leaves time for the
# guest os to deal with the flow of characters. The ideal setting
# depends on how your operating system processes characters. The
# default of 100000 usec (.1 seconds) was chosen because it works
# consistently in Windows.
# If your OS is losing characters during a paste, increase the paste
# delay until it stops losing characters.
#
# KEYMAP:
# This enables a remap of a physical localized keyboard to a
# virtualized us keyboard, as the PC architecture expects.
#
# USER_SHORTCUT:
# This defines the keyboard shortcut to be sent when you press the "user"
# button in the headerbar. The shortcut string is a combination of maximum
# 3 key names (listed below) separated with a '-' character.
# Valid key names:
# "alt", "bksl", "bksp", "ctrl", "del", "down", "end", "enter", "esc",
# "f1", ... "f12", "home", "ins", "left", "menu", "minus", "pgdwn", "pgup",
# "plus", "power", "print", "right", "scrlck", "shift", "space", "tab", "up"
# and "win".
# Examples:
# keyboard: type=mf, serial_delay=200, paste_delay=100000
# keyboard: keymap=gui/keymaps/x11-pc-de.map
# keyboard: user_shortcut=ctrl-alt-del
#=======================================================================
#keyboard: type=mf, serial_delay=250
#=======================================================================
# MOUSE:
# This defines parameters for the emulated mouse type, the initial status
# of the mouse capture and the runtime method to toggle it.
#
# TYPE:
# With the mouse type option you can select the type of mouse to emulate.
# The default value is 'ps2'. The other choices are 'imps2' (wheel mouse
# on PS/2), 'serial', 'serial_wheel', 'serial_msys' (one com port requires
# setting 'mode=mouse') 'inport' and 'bus' (if present). To connect a mouse
# to a USB port, see the 'usb_uhci', 'usb_ohci', 'usb_ehci' or 'usb_xhci'
# options (requires PCI and USB support).
#
# ENABLED:
# The Bochs gui creates mouse "events" unless the 'enabled' option is
# set to 0. The hardware emulation itself is not disabled by this.
# Unless you have a particular reason for enabling the mouse by default,
# it is recommended that you leave it off. You can also toggle the mouse
# usage at runtime (RFB, SDL, Win32, wxWidgets and X11 - see below).
#
# TOGGLE:
# The default method to toggle the mouse capture at runtime is to press the
# CTRL key and the middle mouse button ('ctrl+mbutton'). This option allows
# to change the method to 'ctrl+f10' (like DOSBox), 'ctrl+alt' (like QEMU)
# or 'f12'.
#
# Examples:
# mouse: enabled=1
# mouse: type=imps2, enabled=1
# mouse: type=serial, enabled=1
# mouse: enabled=0, toggle=ctrl+f10
#=======================================================================
mouse: enabled=0
#=======================================================================
# PCI:
# This option controls the presence of a PCI chipset in Bochs. Currently it
# supports the i430FX, i440FX and i440BX chipsets. You can also specify the
# devices connected to PCI slots. Up to 5 slots are available. For these
# combined PCI/ISA devices assigning to slot is mandatory if you want to emulate
# the PCI model: cirrus, ne2k and pcivga. These PCI-only devices are also
# supported, but they are auto-assigned if you don't use the slot configuration:
# e1000, es1370, pcidev, pcipnic, usb_ehci, usb_ohci, usb_xhci and voodoo.
# In case of the i440BX chipset, slot #5 is the AGP slot. Currently only the
# 'voodoo' device can be assigned to AGP.
#
# Example:
# pci: enabled=1, chipset=i440fx, slot1=pcivga, slot2=ne2k
#=======================================================================
pci: enabled=1, chipset=i440fx
#=======================================================================
# CLOCK:
# This defines the parameters of the clock inside Bochs:
#
# SYNC:
# This defines the method how to synchronize the Bochs internal time
# with realtime. With the value 'none' the Bochs time relies on the IPS
# value and no host time synchronization is used. The 'slowdown' method
# sacrifices performance to preserve reproducibility while allowing host
# time correlation. The 'realtime' method sacrifices reproducibility to
# preserve performance and host-time correlation.
# It is possible to enable both synchronization methods.
#
# RTC_SYNC:
# If this option is enabled together with the realtime synchronization,
# the RTC runs at realtime speed. This feature is disabled by default.
#
# TIME0:
# Specifies the start (boot) time of the virtual machine. Use a time
# value as returned by the time(2) system call or a string as returned
# by the ctime(3) system call. If no time0 value is set or if time0
# equal to 1 (special case) or if time0 equal 'local', the simulation
# will be started at the current local host time. If time0 equal to 2
# (special case) or if time0 equal 'utc', the simulation will be started
# at the current utc time.
#
# Syntax:
# clock: sync=[none|slowdown|realtime|both], time0=[timeValue|local|utc]
#
# Example:
# clock: sync=none, time0=local # Now (localtime)
# clock: sync=slowdown, time0=315529200 # Tue Jan 1 00:00:00 1980
# clock: sync=none, time0="Mon Jan 1 00:00:00 1990" # 631148400
# clock: sync=realtime, time0=938581955 # Wed Sep 29 07:12:35 1999
# clock: sync=realtime, time0="Sat Jan 1 00:00:00 2000" # 946681200
# clock: sync=none, time0=1 # Now (localtime)
# clock: sync=none, time0=utc # Now (utc/gmt)
#
# Default value are sync=none, rtc_sync=0, time0=local
#=======================================================================
#clock: sync=none, time0=local
#=======================================================================
# CMOSIMAGE:
# This defines a binary image file with size 128 bytes that can be loaded into
# the CMOS RAM at startup. The rtc_init parameter controls whether initialize
# the RTC with values stored in the image. By default the time0 argument given
# to the clock option is used. With 'rtc_init=image' the image is the source
# for the initial time.
#
# Example:
# cmosimage: file=cmos.img, rtc_init=image
#=======================================================================
#cmosimage: file=cmos.img, rtc_init=time0
#=======================================================================
# private_colormap: Request that the GUI create and use it's own
# non-shared colormap. This colormap will be used
# when in the bochs window. If not enabled, a
# shared colormap scheme may be used. Not implemented
# on all GUI's.
#
# Examples:
# private_colormap: enabled=1
# private_colormap: enabled=0
#=======================================================================
private_colormap: enabled=0

#
# The path should be the name of a disk image file. On Unix, you can use a raw
# device name such as /dev/fd0 on Linux. On win32 platforms, use drive letters
# such as a: or b: as the path. The parameter 'image' works with image files
# only. In that case the size must match one of the supported types.
# The parameter 'type' can be used to enable the floppy drive without media
# and status specified. Usually the drive type is set up based on the media type.
# The optional parameter 'write_protected' can be used to control the media
# write protect switch. By default it is turned off.

# journal= optional filename of the redolog for undoable, volatile and vvfat disks
#
# Point this at a hard disk image file, cdrom iso file, or physical cdrom
# device. To create a hard disk image, try running bximage. It will help you
# choose the size and then suggest a line that works with it.
#
# In UNIX it may be possible to use a raw device as a Bochs hard disk,
# but WE DON'T RECOMMEND IT. In Windows there is no easy way.
#
# In windows, the drive letter + colon notation should be used for cdroms.
# Depending on versions of windows and drivers, you may only be able to
# access the "first" cdrom in the system. On MacOSX, use path="drive"
# to access the physical drive.
#
# The path is mandatory for hard disks. Disk geometry autodetection works with
# images created by bximage if CHS is set to 0/0/0 (cylinders are calculated
# using heads=16 and spt=63). For other hard disk images and modes the
# cylinders, heads, and spt are mandatory. In all cases the disk size reported
# from the image must be exactly C*H*S*512.
#
# Default values are:
# mode=flat, biosdetect=auto, translation=auto, model="Generic 1234"
#
# The biosdetect option has currently no effect on the bios

# BOOT:
# This defines the boot sequence. Now you can specify up to 3 boot drives,
# which can be 'floppy', 'disk', 'cdrom' or 'network' (boot ROM).
# Legacy 'a' and 'c' are also supported.
# Examples:
# boot: floppy
# boot: cdrom, disk
# boot: network, disk
# boot: cdrom, floppy, disk
#=======================================================================
#boot: floppy
boot: cdrom
#=======================================================================
# FLOPPY_BOOTSIG_CHECK: disabled=[0|1]
# Enables or disables the 0xaa55 signature check on boot floppies
# Defaults to disabled=0
# Examples:
# floppy_bootsig_check: disabled=0
# floppy_bootsig_check: disabled=1
#=======================================================================
floppy_bootsig_check: disabled=0

# LOG:
# Give the path of the log file you'd like Bochs debug and misc. verbiage
# to be written to. If you don't use this option or set the filename to
# '-' the output is written to the console. If you really don't want it,
# make it "/dev/null" (Unix) or "nul" (win32). :^(
#
# Examples:
# log: ./bochs.out
# log: /dev/tty
#=======================================================================
#log: /dev/null
log: -
#=======================================================================
# LOGPREFIX:
# This handles the format of the string prepended to each log line.
# You may use those special tokens :
# %t : 11 decimal digits timer tick
# %i : 8 hexadecimal digits of cpu current eip (ignored in SMP configuration)
# %e : 1 character event type ('i'nfo, 'd'ebug, 'p'anic, 'e'rror)
# %d : 5 characters string of the device, between brackets
#
# Default : %t%e%d
# Examples:
# logprefix: %t-%e-@%i-%d
# logprefix: %i%e%d
#=======================================================================
#logprefix: %t%e%d
#=======================================================================
# LOG CONTROLS
#
# Bochs has four severity levels for event logging.
# panic: cannot proceed. If you choose to continue after a panic,
# don't be surprised if you get strange behavior or crashes.
# error: something went wrong, but it is probably safe to continue the
# simulation.
# info: interesting or useful messages.
# debug: messages useful only when debugging the code. This may
# spit out thousands per second.
#
# For events of each level, you can choose to exit Bochs ('fatal'), 'ask',
# 'warn', 'report' or 'ignore'. The choices 'ask' and 'warn' are not supported
# by all guis, since they should bring up a dialog box. The 'warn' dialog is
# designed to confirm errors and the 'ask' dialog is usually used for panics
# and asks the user how to proceed.
#
# It is also possible to specify the 'action' to do for each Bochs facility
# separately (e.g. crash on panics from everything except the cdrom, and only
# report those). See the 'log function' module list in the user documentation.
#
# If you are experiencing many panics, it can be helpful to change
# the panic action to report instead of fatal. However, be aware
# that anything executed after a panic is uncharted territory and can
# cause bochs to become unstable. The panic is a "graceful exit," so
# if you disable it you may get a spectacular disaster instead.
#=======================================================================
panic: action=ask
error: action=report
info: action=report
debug: action=ignore, pci=report # report BX_DEBUG from module 'pci'
#=======================================================================
# DEBUGGER_LOG:
# Give the path of the log file you'd like Bochs to log debugger output.
# If you really don't want it, make it /dev/null or '-'. :^(
#
# Examples:
# debugger_log: ./debugger.out
#=======================================================================
#debugger_log: /dev/null
#debugger_log: debugger.out
debugger_log: -
#=======================================================================
# COM1, COM2, COM3, COM4:
# This defines a serial port (UART type 16550A). In the 'term' mode you can
# specify a device to use as com1. This can be a real serial line, or a pty.
# To use a pty (under X/Unix), create two windows (xterms, usually). One of
# them will run bochs, and the other will act as com1. Find out the tty the com1
# window using the `tty' command, and use that as the `dev' parameter.
# Then do `sleep 1000000' in the com1 window to keep the shell from
# messing with things, and run bochs in the other window. Serial I/O to
# com1 (port 0x3f8) will all go to the other window.
# In socket* and pipe* (win32 only) modes Bochs becomes either socket/named pipe
# client or server. In client mode it connects to an already running server (if
# connection fails Bochs treats com port as not connected). In server mode it
# opens socket/named pipe and waits until a client application connects to it
# before starting simulation. This mode is useful for remote debugging (e.g.
# with gdb's "target remote host:port" command or windbg's command line option
# -k com:pipe,port=\\.\pipe\pipename). Socket modes use simple TCP communication,
# pipe modes use duplex byte mode pipes.
# Other serial modes are 'null' (no input/output), 'file' (output to a file
# specified as the 'dev' parameter and changeable at runtime), 'raw' (use the
# real serial port - partly implemented on win32), 'mouse' (standard serial
# mouse - requires mouse option setting 'type=serial', 'type=serial_wheel' or
# 'type=serial_msys').
#
# Examples:
# com1: enabled=1, mode=null
# com1: enabled=1, mode=mouse
# com2: enabled=1, mode=file, dev=serial.out
# com3: enabled=1, mode=raw, dev=com1
# com3: enabled=1, mode=socket-client, dev=localhost:8888
# com3: enabled=1, mode=socket-server, dev=localhost:8888
# com4: enabled=1, mode=pipe-client, dev=\\.\pipe\mypipe
# com4: enabled=1, mode=pipe-server, dev=\\.\pipe\mypipe
#=======================================================================
#com1: enabled=1, mode=term, dev=/dev/ttyp9
#=======================================================================
# PARPORT1, PARPORT2:
# This defines a parallel (printer) port. When turned on and an output file is
# defined the emulated printer port sends characters printed by the guest OS
# into the output file. On some platforms a device filename can be used to
# send the data to the real parallel port (e.g. "/dev/lp0" on Linux, "lpt1" on
# win32 platforms). The output file can be changed at runtime.
#
# Examples:
# parport1: enabled=1, file="parport.out"
# parport2: enabled=1, file="/dev/lp0"
# parport1: enabled=0
#=======================================================================
parport1: enabled=0, file="parport.out"
#=======================================================================
# SOUND:
# This defines the lowlevel sound driver(s) for the wave (PCM) input / output
# and the MIDI output feature and (if necessary) the devices to be used.
# It can have several of the following properties.
# All properties are in the format sound: property=value
#
# waveoutdrv:
# This defines the driver to be used for the waveout feature.
# Possible values are 'file' (all wave data sent to file), 'dummy' (no
# output) and the platform-dependant drivers 'alsa', 'oss', 'osx', 'sdl'
# and 'win'.
# waveout:
# This defines the device to be used for wave output (if necessary) or
# the output file for the 'file' driver.
# waveindrv:
# This defines the driver to be used for the wavein feature.
# Possible values are 'dummy' (recording silence) and platform-dependent
# drivers 'alsa', 'oss', 'sdl' and 'win'.
# wavein:
# This defines the device to be used for wave input (if necessary).
# midioutdrv:
# This defines the driver to be used for the MIDI output feature.
# Possible values are 'file' (all MIDI data sent to file), 'dummy' (no
# output) and platform-dependent drivers 'alsa', 'oss', 'osx' and 'win'.
# midiout:
# This defines the device to be used for MIDI output (if necessary).
# driver:
# This defines the driver to be used for all sound features with one
# property. Possible values are 'default' (platform default) and all
# other choices described above. Overriding one or more settings with
# the specific driver parameter is possible.
#
# Example for different drivers:
# sound: waveoutdrv=sdl, waveindrv=alsa, midioutdrv=dummy
#=======================================================================
#sound: driver=default, waveout=/dev/dsp. wavein=, midiout=
#=======================================================================
# SPEAKER:
# This defines the PC speaker output mode. In the 'sound' mode the beep
# is generated by the square wave generator which is a part of the
# lowlevel sound support. The 'system' mode is only available on Linux
# and Windows. On Linux /dev/console is used for output and on Windows
# the Beep() function. The 'gui' mode forwards the beep to the related
# gui methods (currently only used by the Carbon gui).
#=======================================================================
speaker: enabled=1, mode=system
#=======================================================================
# SB16:
# This defines the SB16 sound emulation. It can have several of the
# following properties.
# All properties are in the format sb16: property=value
#
# enabled:
# This optional property controls the presence of the SB16 emulation.
# The emulation is turned on unless this property is used and set to 0.
# midimode: This parameter specifies what to do with the MIDI output.
# 0 = no output
# 1 = output to device specified with the sound option (system dependent)
# 2 = MIDI or raw data output to file (depends on file name extension)
# 3 = dual output (mode 1 and 2 at the same time)
# midifile: This is the file where the midi output is stored (midimode 2 or 3).
# wavemode: This parameter specifies what to do with the PCM output.
# 0 = no output
# 1 = output to device specified with the sound option (system dependent)
# 2 = VOC, WAV or raw data output to file (depends on file name extension)
# 3 = dual output (mode 1 and 2 at the same time)
# wavefile: This is the file where the wave output is stored (wavemode 2 or 3).
# loglevel:
# 0=no log
# 1=resource changes, midi program and bank changes
# 2=severe errors
# 3=all errors
# 4=all errors plus all port accesses
# 5=all errors and port accesses plus a lot of extra info
# log: The file to write the sb16 emulator messages to.
# dmatimer:
# microseconds per second for a DMA cycle. Make it smaller to fix
# non-continuous sound. 750000 is usually a good value. This needs a
# reasonably correct setting for the IPS parameter of the CPU option.
#
# Examples for output modes:
# sb16: midimode=2, midifile="output.mid", wavemode=1 # MIDI to file
# sb16: midimode=1, wavemode=3, wavefile="output.wav" # wave to file and device
#=======================================================================
#sb16: midimode=1, wavemode=1, loglevel=2, log=sb16.log, dmatimer=600000
#=======================================================================
# ES1370:
# This defines the ES1370 sound emulation (recording and playback - except
# DAC1+DAC2 output at the same time). The parameter 'enabled' controls the
# presence of the device. The wave and MIDI output can be sent to device, file
# or both using the parameters 'wavemode', 'wavefile', 'midimode' and
# 'midifile'. See the description of these parameters at the SB16 directive.
#
# Examples:
# es1370: enabled=1, wavemode=1 # use 'sound' parameters
# es1370: enabled=1, wavemode=2, wavefile=output.voc # send output to file
#=======================================================================
#es1370: enabled=1, wavemode=1
#=======================================================================
# ne2k: NE2000 compatible ethernet adapter
#
# Format:
# ne2k: enabled=1, ioaddr=IOADDR, irq=IRQ, mac=MACADDR, ethmod=MODULE,
# ethdev=DEVICE, script=SCRIPT, bootrom=BOOTROM
#
# IOADDR, IRQ: You probably won't need to change ioaddr and irq, unless there
