# 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 are currently supported: 'biosdev', 'e1000', 'es1370',
# 'extfpuirq', 'gameport', 'iodebug', 'ne2k', 'parallel', 'pcidev', 'pcipnic',
# 'sb16', 'serial', 'speaker', 'unmapped', 'usb_ohci', 'usb_uhci' and 'usb_xhci'.
#=======================================================================
plugin_ctrl: unmapped=1, biosdev=1, speaker=1, e1000=1, parallel=1, serial=1

#=======================================================================
# 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 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
#   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, x) / Win32 debugger gui (win32)
# "hideIPS"     - disable IPS output in status bar (sdl, wx, x)
# "nokeyrepeat" - turn off host keyboard repeat (sdl, win32, x)
#
# See the examples below for other currently supported options.
#=======================================================================
#display_library: amigaos
#display_library: carbon
#display_library: macintosh
#display_library: nogui
#display_library: rfb, options="timeout=60" # time to wait for client
#display_library: sdl, options="fullscreen" # startup in fullscreen mode
#display_library: term
#display_library: win32
#display_library: wx
#display_library: x

#=======================================================================
# 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

# 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 optional, since it can be calculated from image size.

#
#  COUNT:
#    Set the number of processors:cores per processor:threads per core
#    when Bochs is compiled for SMP emulation.
#    Bochs currently supports up to 8 threads 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
#     The VGA update frequency is based on the emulated clock and the default
#     value is 5. Keep in mind that you must tweak the 'cpu: ips=N' directive
#     to be as close to the number of emulated instructions-per-second your
#     workstation can do, for this to be accurate. If the realtime sync is
#     enabled with the 'clock' option, the value is based on the real time.
#     This parameter can be changed at runtime.

#
# 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"

# BOOT:
# This defines the boot sequence. Now you can specify up to 3 boot drives,

# 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. 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)

# 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:

# 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'), 'report'
# or 'ignore'. On some guis you have the additional choice 'ask'. A gui dialog
# appears asks 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' 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). Note: 'socket' is a shorthand for
# 'socket-client' and 'pipe' for 'pipe-client'. 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), 'raw' (use the real serial port - under
# construction for 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).
#
# Examples:
#   parport1: enabled=1, file="parport.out"
#   parport2: enabled=1, file="/dev/lp0"
#   parport1: enabled=0
#=======================================================================
parport1: enabled=1, file="parport.out"

#=======================================================================
# 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.
# midi: The filename is where the midi data is sent. This can be a
#       device or just a file if you want to record the midi data.
# midimode:
#      0=no data
#      1=output to device (system dependent. midi denotes the device driver)
#      2=SMF file output, including headers
#      3=output the midi data stream to the file (no midi headers and no
#        delta times, just command and data bytes)
# wave: This is the device/file where wave output is stored
# wavemode:
#      0=no data
#      1=output to device (system dependent. wave denotes the device driver)
#      2=VOC file output, incl. headers
#      3=output the raw wave stream to the file
# log:  The file to write the sb16 emulator messages to.
# 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
# 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 devices:
#   sb16: midimode=1, midi="", wavemode=1, wave=""           # win32
#   sb16: midimode=1, midi=alsa:128:0, wavemode=1, wave=alsa # Linux with ALSA
#=======================================================================
#sb16: midimode=1, midi=/dev/midi00, wavemode=1, wave=/dev/dsp, loglevel=2, log=sb16.log, dmatimer=600000

#=======================================================================
# ES1370:
# This defines the ES1370 sound emulation. The parameter 'enabled' controls the
# presence of the device. In addition to this, it must be loaded with 'plugin_ctrl'
# and assigned to a PCI slot. The 'wavedev' parameter is similar to the 'wave'
# parameter of the SB16 soundcard. The emulation supports recording and playback
# (except DAC1+DAC2 output at the same time).
#
# Examples:
#   es1370: enabled=1, wavedev=""       # win32
#   es1370: enabled=1, wavedev=alsa     # Linux with ALSA
#=======================================================================
#es1370: enabled=1, wavedev=alsa

#=======================================================================
# KEYBOARD_SERIAL_DELAY:
# Approximate time in microseconds that it takes one character to
# be transfered from the keyboard to controller over the serial path.
# Examples:
#   keyboard_serial_delay: 200
#=======================================================================
keyboard_serial_delay: 250

#=======================================================================
# KEYBOARD_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.
#
# Examples:
#   keyboard_paste_delay: 100000
#=======================================================================
keyboard_paste_delay: 100000

#=======================================================================
# 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' and 'serial_msys' (one com port requires
#  setting 'mode=mouse'). To connect a mouse to an USB port, see the 'usb_uhci',
#  'usb_ohci' 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' (replaces win32 'legacyF12' option).
#
# Examples:
#   mouse: enabled=1
#   mouse: type=imps2, enabled=1
#   mouse: type=serial, enabled=1
#   mouse: enabled=0, toggle=ctrl+f10
#=======================================================================
mouse: enabled=0

#=======================================================================
# 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

#=======================================================================
# fullscreen: ONLY IMPLEMENTED ON AMIGA
#             Request that Bochs occupy the entire screen instead of a
#             window.

# Examples:
#   fullscreen: enabled=0
#   fullscreen: enabled=1
#=======================================================================
#fullscreen: enabled=0

#=======================================================================
# 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.
#
# 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.
#
# 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.

#=======================================================================
# KEYBOARD_MAPPING:
# This enables a remap of a physical localized keyboard to a
# virtualized us keyboard, as the PC architecture expects.
# If enabled, the keymap file must be specified.
#
# Examples:
#   keyboard_mapping: enabled=1, map=gui/keymaps/x11-pc-de.map
#=======================================================================
keyboard_mapping: enabled=0, map=

#=======================================================================
# KEYBOARD_TYPE:
# Type of keyboard return by a "identify keyboard" command to the
# keyboard controler. 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.
#
# Examples:
#   keyboard_type: mf
#=======================================================================
#keyboard_type: mf

#=======================================================================
# 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", "right", "shift", "space", "tab", "up", "win", "print" and "power".
#
# Example:
#   user_shortcut: keys=ctrl-alt-del
#=======================================================================
#user_shortcut: keys=ctrl-alt-del

#=======================================================================
# PCI:
# This option controls the presence of a PCI chipset in Bochs. Currently it only
# supports the i440FX chipset. You can also specify the devices connected to
# PCI slots. Up to 5 slots are available. These devices are currently supported:
# cirrus, e1000, es1370, ne2k, pcivga, pcidev, pcipnic, usb_ohci and usb_xhci.
#
# Example:
#   pci: enabled=1, chipset=i440fx, slot1=pcivga, slot2=ne2k
#=======================================================================
pci: enabled=1, chipset=i440fx, slot1=e1000

#=======================================================================
# 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'
# 'hub' and 'printer'). NOTE: UHCI must be loaded with 'plugin_ctrl'.
#
# The optionsX parameter can be used to assign specific options to the device
# connected to the corresponding USB port. Currently this feature is only used
# to set the speed reported by device and by the 'disk' device to specify
# an alternative redolog file of some image modes.
#
# 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 an 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 an 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.
#
# 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. It would probably be nice to
# overwrite the file instead, asking user first.

# USB_OHCI:
# This option controls the presence of the USB OHCI host controller with a

# to a PCI slot and loaded with 'plugin_ctrl'.
#=======================================================================
#usb_xhci: enabled=1

#=======================================================================
# CMOSIMAGE:
# This defines image file 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

#=======================================================================
# MAGIC_BREAK:
# This enables the "magic breakpoint" feature when using the debugger.
# The useless cpu instruction XCHG BX, BX causes Bochs to enter the
# debugger mode. This might be useful for software development.
#
# Example:
#   magic_break: enabled=1
#=======================================================================
#magic_break: enabled=1
magic_break: enabled=1

#=======================================================================
# PORT_E9_HACK:
# The 0xE9 port doesn't exists in normal ISA architecture. However, we
# define a convention here, to display on the console of the system running
# Bochs anything that is written to it. The idea is to provide debug output
# very early when writing BIOS or OS code for example, without having to
# bother with setting up a serial port or etc. Reading from port 0xE9 will
# will return 0xe9 to let you know if the feature is available.
# Leave this 0 unless you have a reason to use it.

# Example:
#   port_e9_hack: enabled=1
#=======================================================================

# DEBUG_SYMBOLS:
# This loads symbols from the specified file for use in Bochs' internal
