# 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.
# There are two choices of configuration interface: a text mode version
# called "textconfig" and a graphical version called "wx".  The text
# mode version uses stdin/stdout and is always compiled in.  The graphical
# version 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: 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)
#   beos           use native BeOS libraries
#   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 option to control their
# behaviour. See the examples below for currently supported options.

# 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 ROM BIOS is usually loaded
# starting at address 0xf0000, and it is exactly 64k long.
# You can also use the environment variable $BXSHARE to specify the
# location of the BIOS.
# The usage of external large BIOS images (up to 512k) at memory top is
# now supported, but we still recommend to use the BIOS distributed with
# Bochs. Now the start address can be calculated from image size.
#=======================================================================
romimage: file=$BXSHARE/BIOS-bochs-latest, address=0xf0000
#romimage: file=mybios.bin, address=0xfff80000 # 512k at memory top
#romimage: file=mybios.bin # calculate start address from image size

#=======================================================================
# CPU:
# This defines cpu-related parameters inside Bochs:
#
#  COUNT:
#  Set the number of processors when Bochs is compiled for SMP emulation.
#  Bochs currently supports up to 8 processors. If Bochs is compiled
#  without SMP support, it won't accept values different from 1.
#
#  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 workstation's capability.
#  Measured IPS value will then be logged into your log file or 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:
#  Machine                                         Mips
# ________________________________________________________________
#  2.1Ghz Athlon XP with Linux 2.6/g++ 3.4         12 to 15 Mips
#  1.6Ghz Intel P4 with Win2000/g++ 3.3             5 to  7 Mips
#  650Mhz Athlon K-7 with Linux 2.4.4/egcs-2.91.66  2 to  2.5 Mips
#  400Mhz Pentium II with Linux 2.0.36/egcs-1.0.3   1 to  1.8 Mips

# MEGS
# Set the number of Megabytes of physical memory you want to emulate.

# OPTROMIMAGE[1-4]:
# You may now load up to 4 optional ROM images. Be sure to use a 
# read-only area, typically between C8000 and EFFFF. These optional
# ROM images should not overwrite the rombios (located at
# F0000-FFFFF) and the videobios (located at C0000-C7FFF).
# Those ROM images will be initialized by the bios if they contain 
# the right signature (0x55AA) and a valid checksum.
# It can also be a convenient way to upload some arbitrary code/data
# in the simulation, that can be retrieved by the boot loader

# 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.
