+# 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'.

+#=======================================================================
+# 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.

+# 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.

+#
+#  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 avaiable 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.
+#

+# 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 and 'cirrus' for Cirrus SVGA support.
+#
+#   UPDATE_FREQ
+#     This parameter specifies the number of display updates per second.
+#     The VGA update timer now uses the realtime engine and the default
+#     value is 5. This parameter can be changed at runtime.
+#
+#   REALTIME
+#     If set to 1, the VGA timer is based on realtime, otherwise it is based
+#     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. The default value is 1.

+# 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' and 'voodoo2'. The Voodoo2 support is
+# not yet complete.
+#
+# Examples:
+#   voodoo: enabled=1, model=voodoo1
+#=======================================================================
+#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

+#  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 only
+# supports the i430FX and i440FX 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.
+#
+# 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

+# 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
+#=======================================================================

+# 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.

+# 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

+# win32 platforms). The output file can be changed at runtime.

+# 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
+# are IRQ conflicts. These arguments are ignored when assign the ne2k to a
+# PCI slot.
+#
+# MAC: The MAC address MUST NOT match the address of any machine on the net.
+# Also, the first byte must be an even number (bit 0 set means a multicast
+# address), and you cannot use ff:ff:ff:ff:ff:ff because that's the broadcast
+# address.  For the ethertap module, you must use fe:fd:00:00:00:01.  There may
+# be other restrictions too.  To be safe, just use the b0:c4... address.
+#
+# ETHDEV: The ethdev value is the name of the network interface on your host
+# platform.  On UNIX machines, you can get the name by running ifconfig.  On
+# Windows machines, you must run niclist to get the name of the ethdev.
+# Niclist source code is in misc/niclist.c and it is included in Windows 
+# binary releases.
+# The 'socket' module uses this parameter to specify the UDP port for
+# receiving packets and (optional) the host to connect.
+#
+# SCRIPT: The script value is optional, and is the name of a script that 
+# is executed after bochs initialize the network interface. You can use 
+# this script to configure this network interface, or enable masquerading.
+# This is mainly useful for the tun/tap devices that only exist during
+# Bochs execution. The network interface name is supplied to the script
+# as first parameter.
+# The 'slirp' module uses this parameter to specify a config file for
+# setting up an alternative IP configuration or additional features.
+# The 'vnet' module uses this parameter to specify an alternative
+# log file name.
+#
+# BOOTROM: The bootrom value is optional, and is the name of the ROM image
+# to load. Note that this feature is only implemented for the PCI version of
+# the NE2000.
+#
+# If you don't want to make connections to any physical networks,
+# you can use the following 'ethmod's to simulate a virtual network.
+#   null: All packets are discarded, but logged to a few files.
+#   vde:  Virtual Distributed Ethernet
+#   vnet: ARP, ICMP-echo(ping), DHCP and read/write TFTP are simulated.
+#         The virtual host uses 192.168.10.1.
+#         DHCP assigns 192.168.10.2 to the guest.
+#         TFTP uses the 'ethdev' value for the root directory and doesn't
+#         overwrite files.
+# socket: Connect up to 6 Bochs instances with external program 'bxhub'
+#         (simulating an ethernet hub). It provides the same services as the
+#         'vnet' module and assigns IP addresses like 'slirp' (10.0.2.x).

+# USB_UHCI:
+# This option controls the presence of the USB root hub which is a part
+# of the i440FX PCI chipset. With the portX parameter you can connect devices
+# to the hub (currently supported: 'mouse', 'tablet', 'keypad', 'disk', 'cdrom',
+# 'floppy', 'hub' and 'printer').
+#
+# If you connect the mouse or tablet to one of the ports, Bochs forwards the
+# mouse movement data to the USB device instead of the selected mouse type.
+# When connecting the keypad to one of the ports, Bochs forwards the input of
+# the numeric keypad to the USB device instead of the PS/2 keyboard.
+#
+# To connect a 'flat' mode image as a USB hardisk you can use the 'disk' device
+# with the path to the image separated with a colon. To use other disk image modes
+# similar to ATA disks the syntax 'disk:mode:filename' must be used (see below).
+#
+# To emulate a USB cdrom you can use the 'cdrom' device name and the path to
+# an ISO image or raw device name also separated with a colon. An option to
+# insert/eject media is available in the runtime configuration.
+#
+# To emulate a USB floppy you can use the 'floppy' device with the path to the
+# image separated with a colon. To use the VVFAT image mode similar to the
+# legacy floppy the syntax 'floppy:vvfat:directory' must be used (see below).
+# An option to insert/eject media is available in the runtime configuration.
+#
+# The device name 'hub' connects an external hub with max. 8 ports (default: 4)
+# to the root hub. To specify the number of ports you have to add the value
+# separated with a colon. Connecting devices to the external hub ports is only
+# available in the runtime configuration.
+#
+# The device 'printer' emulates the HP Deskjet 920C printer. The PCL data is
+# sent to a file specified in bochsrc.txt. The current code appends the PCL
+# code to the file if the file already existed. The output file can be
+# changed at runtime.
+#
+# The optionsX parameter can be used to assign specific options to the device
+# connected to the corresponding USB port. Currently this feature is used to
+# set the speed reported by device ('low', 'full', 'high' or 'super'). The
+# availabe speed choices depend on both HC and device. The option 'debug' turns
+# on debug output for the device at connection time.
+# For the USB 'disk' device the optionsX parameter can be used to specify an
+# alternative redolog file (journal) of some image modes. For 'vvfat' mode USB
+# disks the optionsX parameter can be used to specify the disk size (range
+# 128M ... 128G). If the size is not specified, it defaults to 504M.
+# For the USB 'floppy' device the optionsX parameter can be used to specify an
+# alternative device ID to be reported. Currently only the model "teac" is
+# supported (can fix hw detection in some guest OS). The USB floppy also
+# accepts the parameter "write_protected" with valid values 0 and 1 to select
+# the access mode (default is 0).
