# You may now use double quotes around pathnames, in case # your pathname includes spaces. #======================================================================= # 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 option to control their # behaviour.

The ROM BIOS is usually loaded # starting at address 0xf0000, and it is exactly 64k long. Another option # is 128k BIOS which is loaded at address 0xe0000. # You can also use the environment variable $BXSHARE to specify the # location of the BIOS. # The usage of external large BIOS images (up to 512k) at memory top is # now supported, but we still recommend to use the BIOS distributed with # Bochs. The start address optional, since it can be calculated from image size. #======================================================================= romimage: file=$BXSHARE/BIOS-bochs-latest #romimage: file=bios/seabios-0.5.1.bin #romimage: file=mybios.bin, address=0xfff80000 # 512k at memory top #======================================================================= # CPU: # This defines cpu-related parameters inside Bochs: # # 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 ! # # 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. # # 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. # # Examples: # # Bochs Machine/Compiler Mips # ______________________________________________________________________ # 2.4.6 3.4Ghz Intel Core i7 2600 with Win7x64/g++ 4.5.2 85 to 95 Mips # 2.3.7 3.2Ghz Intel Core 2 Q9770 with WinXP/g++ 3.4 50 to 55 Mips # 2.3.7 2.6Ghz Intel Core 2 Duo with WinXP/g++ 3.4 38 to 43 Mips # 2.2.6 2.6Ghz Intel Core 2 Duo with WinXP/g++ 3.4 21 to 25 Mips # 2.2.6 2.1Ghz Athlon XP with Linux 2.6/g++ 3.4 12 to 15 Mips #======================================================================= cpu: count=1, ips=50000000, reset_on_triple_fault=1, ignore_bad_msrs=1, msrs="msrs.def" #======================================================================= # CPUID: # # This defines features and functionality supported by Bochs emulated CPU: # # MMX: # Select MMX instruction set support. # This option exists only if Bochs compiled with BX_CPU_LEVEL >= 5. # # APIC: # Select APIC configuration (LEGACY/XAPIC/X2APIC). # This option exists only if Bochs compiled with BX_CPU_LEVEL >= 5. # # SEP: # Select SYSENTER/SYSEXIT instruction set support. # This option exists only if Bochs compiled with BX_CPU_LEVEL >= 6. # # SSE: # Select SSE instruction set support. # Any of NONE/SSE/SSE2/SSE3/SSSE3/SSE4_1/SSE4_2 could be selected. # This option exists only if Bochs compiled with BX_CPU_LEVEL >= 6. # # AES: # Select AES instruction set support. # This option exists only if Bochs compiled with BX_CPU_LEVEL >= 6. # # MOVBE: # Select MOVBE Intel(R) Atom instruction support. # This option exists only if Bochs compiled with BX_CPU_LEVEL >= 6. # # XSAVE: # Select XSAVE extensions support. # This option exists only if Bochs compiled with BX_CPU_LEVEL >= 6. # # XSAVEOPT: # Select XSAVEOPT instruction support. # This option exists only if Bochs compiled with BX_CPU_LEVEL >= 6. # # AVX: # Select AVX instruction set support. # This option exists only if Bochs compiled with --enable-avx option. # # AVX_F16C: # Select AVX float16 convert instructions support. # This option exists only if Bochs compiled with --enable-avx option. # # 1G_PAGES: # Enable 1G page size support in long mode. # This option exists only if Bochs compiled with x86-64 support. # # PCID: # Enable Process-Context Identifiers (PCID) support in long mode. # This option exists only if Bochs compiled with x86-64 support. # # FSGSBASE: # Enable GS/GS BASE access instructions support in long mode. # This option exists only if Bochs compiled with x86-64 support. # # SMEP: # Enable Supervisor Mode Execution Protection (SMEP) support. # This option exists only if Bochs compiled with BX_CPU_LEVEL >= 6. # # MWAIT: # Select MONITOR/MWAIT instructions support. # This option exists only if Bochs compiled with --enable-monitor-mwait. # # 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. # # VENDOR_STRING: # Set the CPUID vendor string returned by CPUID(0x0).

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).

Currently only the output of the DAC2 is sent to the wave device. # # 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' # or 'usb_ohci' option (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 #screenmode: name="sample" #======================================================================= # ne2k: NE2000 compatible ethernet adapter # # Examples: # ne2k: ioaddr=IOADDR, irq=IRQ, mac=MACADDR, ethmod=MODULE, ethdev=DEVICE, script=SCRIPT # # 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 # # 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. # #======================================================================= # ne2k: ioaddr=0x300, irq=9, mac=fe:fd:00:00:00:01, ethmod=fbsd, ethdev=en0 #macosx # ne2k: ioaddr=0x300, irq=9, mac=b0:c4:20:00:00:00, ethmod=fbsd, ethdev=xl0 # ne2k: ioaddr=0x300, irq=9, mac=b0:c4:20:00:00:00, ethmod=linux, ethdev=eth0 # ne2k: ioaddr=0x300, irq=9, mac=b0:c4:20:00:00:01, ethmod=win32, ethdev=MYCARD # ne2k: ioaddr=0x300, irq=9, mac=fe:fd:00:00:00:01, ethmod=tap, ethdev=tap0 # ne2k: ioaddr=0x300, irq=9, mac=fe:fd:00:00:00:01, ethmod=tuntap, ethdev=/dev/net/tun0, script=./tunconfig # ne2k: ioaddr=0x300, irq=9, mac=b0:c4:20:00:00:01, ethmod=null, ethdev=eth0 # ne2k: ioaddr=0x300, irq=9, mac=b0:c4:20:00:00:01, ethmod=vde, ethdev="/tmp/vde.ctl" # ne2k: ioaddr=0x300, irq=9, mac=b0:c4:20:00:00:01, ethmod=vnet, ethdev="c:/temp" # ne2k: mac=b0:c4:20:00:00:01, ethmod=slirp, script=/usr/local/bin/slirp #======================================================================= # pnic: Bochs/Etherboot pseudo-NIC # # Example: # pnic: enabled=1, mac=MACADDR, ethmod=MODULE, ethdev=DEVICE, script=SCRIPT # # The pseudo-NIC accepts the same syntax (for mac, ethmod, ethdev, script) and # supports the same networking modules as the NE2000 adapter.

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, 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 #======================================================================= # 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'). # # 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_uhci: enabled=1 #usb_uhci: enabled=1, port1=mouse, port2=disk:usbstick.img #usb_uhci: enabled=1, port1=hub:7, port2=disk:growing:usbdisk.img #usb_uhci: enabled=1, port2=disk:undoable:usbdisk.img, options1=journal:redo.log #usb_uhci: enabled=1, port1=printer:printdata.bin, port2=cdrom:image.iso #======================================================================= # USB_OHCI: # This option controls the presence of the USB OHCI host controller with a # 2-port hub.

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 #======================================================================= #port_e9_hack: enabled=1 #======================================================================= # DEBUG_SYMBOLS: # This loads symbols from the specified file for use in Bochs' internal # debugger.
