# 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

#=======================================================================
# 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
#   term           text only, uses curses/ncurses library, cross platform
#   rfb            provides an interface to AT&T's VNC viewer, cross platform
#   wx             use wxWindows library, cross platform
#   nogui          no display at all
#
# NOTE: if you use the "wx" configuration interface, you must also use
# the "wx" display library.

# You now need to load a ROM BIOS into F0000-FFFFF.  I've wiped

# 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).
# It can also be a convenient way to upload some arbitary code/data
# in the simulation, that can be retrieved by the boot loader

# ATA[0-3]-MASTER, ATA[0-3]-SLAVE
#
# This defines the type and characteristics of all attached ata devices:

#   path=       path of the image
#   cylinders=  only valid for disks
#   heads=      only valid for disks
#   spt=        only valid for disks

#   translation=type of transation of the bios, only for disks [none|lba|large|rechs|auto]
#   model=      string returned by identify device command
#   
# 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.
