Selecting CPU MODEL from .bochsrc automatically chooses real HW CPUID and also configures Bochs emulator to emulate this specific CPU including all its features only.
Supported CPUs to choose from:
core2_extreme_x9770
corei7_sandy_bridge_2600K
p4_prescott_celeron_336
'vga_update_interval' option. The screen update frequency is still based on
the emulated clock unless the realtime sync is enabled with the 'clock' option.
TODO: rewrite the virt_timer code to support realtime screen updates
independent from 'clock' setting.
- fixed changing parameter 'update_freq' at runtime (timer object and blink counter)
connected device. For now this feature is only used by the 'disk' device to
specify an alternative redolog filename of some image modes.
- added new methods set_option() and timer() to the base class usb_device_c.
The timer() method is periodicly called from the HC's frame timer code.
- moved runtime device change stuff from the parameter handler to the end of
timer() methods of all hubs. This makes sure that all parameters for the
device have been set at connect time. TODO: this technique could also be used
for the floppy and cdrom media change.
the SF patch #1539417, but rewritten from scratch (patch too old). Differences
to the original version:
* internal parameter name "readonly"
* update parameter if floppy image is readonly
* wxWidgets support
* documentation updates
* no specific toolbar buttons
the default Bochs method using the CTRL key and the middle mouse button there
are now the choices CTRL+F10 (like DOSBox) and CTRL+ALT (like QEMU).
* currently implemented in the X11 and SDL guis only
* TODO: porting to wxWidgets and Win32, documentation updates
enable the floppy drive without media and status specified
- simplified parsing of floppy bochsrc options
- default media status for floppy drives set to BX_EJECTED
- cdrom drives no longer need the path to be set in bochsrc (empty path had
disabled the device in the previous version)
- simplified ATA device setup in bochsrc parser
* initialize plugin system before parsing bochsrc and command line
* pass previous value to bx_param_string_c handler
* load / unload plugin in bx_param_string_handler()
* handle user plugins after optional ones in plugin device init, reset and
save/restore functions
* added new siminterface method unregister_user_option()
* removed first version of config option handling for user plugins
* added new parameter subtree for user-defined options
* added new bx_list_c method remove()
* removed unused bx_devmodel_c method init_mem()
* "pipe-server" (win32 only): It makes bochs a named pipe server so other
application can communicate with it using pipes API. Useful e.g. for remote
kernel debugging.
* "pipe-client" (win32 only)
* "socket-server": for the use with gdb
- removed obsolete structures and members from the USB code
- removed mouse type 'usb' (USB mouse and tablet override selected mouse type
when connected)
- user doc: mention vmware 4 disk image support
generate absolute x/y values if tablet connected)
- store device name string in member d.devname
- report unknown/unsupported requests as errors
- usb_msd: removed unnecessary type definition
string. This is better for devices that need to know all it's options when
connecting to the port. Device name and option should be separated with a
colon. The USB device 'disk' now uses this format ('disk:usbdisk.img).
- the pciusb plugin must be linked with cdrom.o
- missing reset of PCI slot options added
- parsing of i440fxsupport config line rewritten
- vga_update_interval default value changed to 40000 and docs updated
- some more documentation updated including default values for some bochsrc options
number of steps to do, the step rate time and the date rate
- the option floppy_command_delay is obsolete now, since all floppy delays are
based on the hardware specs. The usage of this option caused a warning now.
optromimage. You can load up to 4 arbitrary binary images into RAM.
I didn't do any checking on the addresses, so it's up to you to make
sure they don't collide with anything else. Should only be used for
placing files into standard RAM.
* added a few more intra-documentation links
* sync'ed software license introduction line among sections
* added Cirrus video card hint and bypass hardware check parameter
to Windows 98 section
- descriptions of 'romimage' and 'megs' updated
- usage of old-style syntax for 'user_shortcut' now causes a warning
- deprecated options 'pit' and 'time0' now cause an error
- old disk options completely removed from bochsrc parser
- documentation changes: 'pit' and 'time0' removed, 'user_shortcut' updated
with a '-' character. Added support for some more keys. The old-style syntax
is still supported for a few key combinations.
- updated/added documentation for the 'cmosimage' option
- removed obsolete parameters for usb1 and pnic (now assigned by the PCI BIOS)
- PCI base address register mechanism now leaves the flags untouched
- missing reset of pnic options added
- cmos image options renamed
- new cmos option controls the usage of the RTC values from image
- report time0 in use after handling the cmos image stuff
- MSVC warning fixed
* simple read-only TFTP server implemented
* don't discard IPv4 packets larger than the length stored in header
- TFTP server uses ethdev value for the root directory
- removed trailing newlines in messages
- log file description improved (disable logging on win32)
- usb1 description added
- vgaromimage: VGABIOS-lgpl-latest is now the default
- wxWindows changed to wxWidgets
* updated description for bochsrc options com[1-4], mouse, i440fxsupport
* added description for bochsrc option 'gdbstub'
- updated syntax of bochsrc option 'vgaromimage'
- updated remark for the usage of the LGPL'd VGABIOS and Windows NT 4.0
- updated some descriptions in the bochsrc sample
#1079240 by Ben Lunt. There are still some problems:
- PS/2 mouse is always present (some code to emulate a disconnected mouse needed)
- PS/2 wheel mouse doesn't work properly
- serial wheel mouse detected as a standard mouse and doesn't work at all
- vgaromimage option now compatible with the other rom options. Old style syntax
(without 'file=...") is still supported.
- load order for the rom images fixed (system, vga, other)
- rom images sizes not multiple 512 cause a BX_INFO for now. The original check
will be enabled after updating the vgabios files
- optromimage error messages fixed
- some updates of the bochsrc sample
data written to the port and where to get the data read from it. Available
modes are 'null' (no input/output), 'file' (output to a file specified as
the 'dev' parameter), 'term' (serial terminal) and 'raw' (use the real serial
port - under construction for win32).
- descriptions for serial and parallel options in bochsrc sample updated
* up to 5 slots can be specified with the 'i440fxsupport' config option
* the pci slot number are hardwired to pci device numbers
* the 'devfunc' value is returned the calling device (useful for multi-function
devices)
* the core of the i440FX chipset is hardwired to pci device 1 + 2; usb is still
optional and appears at device 1, function 2
- ne2k: enable pci features if connected to a pci slot
- ne2k: asic data port supports 32-bit access if ne2k-pci is active
- pci2isa: improved error messages for ELCR1 and ELCR2
- pit: and time0: options are still supported but deprecated
- warn when parsing deprecated directives
- fix wrong number of ata_device_translation_names
- still to do:
- setting time0 to utc is not yet supported
- the man page, user guide and .bochsrc still need to be updated
with the new options
You can now choose for each disk on the ata interfaces the
disk mode, between :
- flat : one file flat layout
- concat : multiple files layout
- external : developer's specific, through a C++ class
- dll : developer's specific, through a DLL
- sparse : stackable, commitable, rollbackable
- vmware3 : vmware3 disk support
- undoable : flat file with commitable redolog
- growable : growing file
- volatile : flat file with volatile redolog
- z-undoable : gziped flat file with commitable redolog
- z-volatile : gziped flat file with volatile redolog
A new "bxcommit" utility can merge commitable redologs to
flat images.
- function userbutton_handler(): stop parsing the shortcut string if the
key name is invalid
- function userbutton_handler(): incrementing variable 'len' simplified
- function snapshot_checker(): fixed a warning
there is one more option in the configuration file "debugger_log"
if the debugger is compiled in, all debugger output will be also
written to this file. Note: wxWindow config interface is not updated yet
a control panel, but now we're calling it a text configuration interface.

- if translation=auto :
. translation=none if cylinders <=1024 and heads <=16
. translation=large if cylinders * heads <= 131072
. transaltion=lba otherwise
- changes default translation value to "auto"
- add example in .bochsrc
section title, and less like the grammar that you're supposed to use.
Someone on irc was confused because it was written in uppercase, but then
bochs did not accept the uppercase ATA0-MASTER parameter.
- Features :
. number of active channels defined at boot-time config
. new options in bochsrc
. up to 8 devices support (disks or cdroms)
. up to 4 cdrom devices can be changed at runtime config
. wxwindows config interface
to "*_ENABLED"
- bx_serial_options for all 4 ports moved into an array com[4]
- serial port com1 is enabled by default
- detection of com2, com3 and com4 config options disabled for now
- new parameter "enabled" added to the serial bochsrc options
- error handling for serial and parallel bochsrc options changed. The unhandled
BX_PANICs are replaced by BX_ERRORs.
- new function bx_write_serial_options() added
- serial destructor restores original terminal settings only when serial port
is enabled and the tty_id is valid
parport1 with the new option "enabled". The old option "enable" only
controlled the output. The parport1 is enabled with no output by default.
Changes:
* bochrc option "enable" replaced by "enabled"
* parport option "Oenable" replaced by "Opresent"
* bx_parport_options par1 and par2 replaced by an array par[2]
* initialize parport1 resources only when enabled
* renamed variable "parport_init_list" to "par_ser_init_list" since it
contains parport and serial options
* documentation and bochsrc updates
- the parport variables "output" and "initmode" now belong to the bx_par_t
structure
- TODO: add parport2 (disabled by default), parport detection in the bios
the guest OS. The shortcut can be defined in the bochsrc or in the config
interface. It is possible to change it at runtime.
These shortcuts are currently recognized:
ctrlaltdel, ctrlaltesc, ctrlaltf1, alttab
Here is the list of changes:
* userbutton.h and userbutton.xpm added in gui/bitmaps
* config options for the userbutton shortcut added
* initialize the new button in the gui.cc
* the new userbutton handler generates keypresses and relaeses depending on
the shortcut keyword
* the gui stops adding buttons to the headerbar if not enough space is left.
This can happen when the screen width is 320 pixels (done for X11 only).
* TODO: build a dialog box for the wxWindows gui
to describe the format of the log prefix. This option can be any string
with special tokens being replaced at run time :
# %t : 11 decimal digits timer tick
# %i : 8 hexadecimal digits of cpu0 current eip
# %e : 1 character event type ('i'nfo, 'd'ebug, 'p'anic, 'e'rror)
# %d : 5 characters string of the device, between brackets
the default is "%t%i%d", so the logprefix is the same as before.
New tokens can be easily added or changed if needed.

floppy_bootsig_check: disabled=[0|1]. It is not disabled by default.
Sorry for any inconvenience it could cause
- changed the default (if cmos reg is 0) behavior for the floppy boot signature
check, so the new bios is compatible with older bochs binaries (useful if we
want to use the new bios when we release 1.4.1) :
1 : disabled
0 : enabled
- added info at launch time about the boot device and the floppy boot signature
check
- added a "LBA capable" flag in the ata controller
- fixed opened netdevice name (/dev/net/tun...)
- fixed test on iface name (tun instead of tap)
- cosmetic changes
- added example in .bochsrc
Much of these fixes have been contributed by Frederic Bothamy
Here are the patches (without the serial name fix). Let me know if you want
me to change that. Oh, FYI, my changes also open up the com1 terminal in raw
mode, which makes the emulation much more accurate. You'll also notice that
I added infrastructure for com2->4 in the option parsing. I didn't add it to
the serial code, as I think a bunch of things need to be untangled before
that can work.
interface menus. Parallel port #1 is implemented, and I left stubs for
parallel port #2 in case we want to ever add it. If the parallel port
is enabled, the init method of parallel.cc does an fopen() on the output
file. If disabled, or if the fopen fails, the file handler remains
NULL and no characters are printed. There is no attempt to enable/disable
the operation of the parallel port, only the output to a file.
