This may # spit out thousands per second. # # For events of each level, you can choose to crash, report, or ignore. # TODO: allow choice based on the facility: e.g. crash on panics from # everything except the cdrom, and only report those. # # 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 #======================================================================= # mouse: Not used in any of the GUI specific modules, but the option # bx_options.mouse_enabled is set to this value. The idea, # is that the GUI code should not generate mouse events when # not enabled. The hardware emualation itself is not disabled # by this. This is to facilitate deterministic runs of bochs. # # Examples: # mouse: enabled=1 # mouse: enabled=0 # # I wouldn't recommend enabling the mouse by default, unless you have a # really good reason to do so. #======================================================================= # disable the mouse, since DLX is text only mouse: enabled=0 #======================================================================= # 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. # # NOTE: In Bochs 1.4, keyboard mapping is only 100% implemented on X windows. # However, the key mapping tables are used in the paste function, so in the # DLX Linux example I'm enabling keyboard_mapping so that paste will work. # Cut & Paste is currently implemented on win32 and X windows only. # # Examples: # keyboard_mapping: enabled=1, map=gui/keymaps/x11-pc-de.map #======================================================================= # enable key mapping, using US layout as default. # keyboard_mapping: enabled=1, map=../keymaps/x11-pc-us.map #======================================================================= # USER_SHORTCUT: # This defines the keyboard shortcut to be sent when you press the "user" # button in the headerbar.

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 #======================================================================= # FLOPPY_COMMAND_DELAY: # Time in microseconds to wait before completing some floppy commands # such as read/write/seek/etc, which normally have a delay associated. # I had this hardwired to 50,000 before. # # Examples: # floppy_command_delay: 50000 #======================================================================= # floppy_command_delay: 500 #======================================================================= # IPS: # Emulated Instructions Per Second.
