Changes in 2.0 (December 2002):
|
||||
|
||||
- configure script/compile/porting to other OSes
|
||||
- configure script/compile/porting to other OSes/installation
|
||||
- added plugin architecture (Bryce, Christophe, Volker)
|
||||
- Plugins are shared libraries that can be loaded on demand. Example:
|
||||
the serial device is implemented as a plugin. In UNIX, the
|
||||
serial plugin is called libbx_serial.so. When Bochs reads its
|
||||
configuration file, if the serial device is enabled it loads
|
||||
libbx_serial.so.
|
||||
- plugins supported on Linux, Solaris, MacOS X using libtool,
|
||||
Cygwin using dlltool.
|
||||
- the Linux binary RPMs are built with plugin support
|
||||
- to compile with plugins, configure with --enable-plugins
|
||||
- add #if's around all files which are conditionally compiled such
|
||||
as cdrom.cc and sb16.cc. This makes it possible to compile every
|
||||
source file all the time, which has the potential to simplify the
|
||||
configure script and makefiles. At present we only take advantage
|
||||
of this capability in the win32 VC++ workspace.
|
||||
- the MacOS9 port has been updated so that it works again (Christophe)
|
||||
- better support for FHS standard (Robert Millan, Volker)
|
||||
See patches 551811 and 650066.
|
||||
|
||||
- command line
|
||||
- fixed up our command line options (Volker, Bryce, Christophe)
|
||||
Usage: bochs [flags] [bochsrc options]
|
||||
-n no configuration file
|
||||
-f configfile specify configuration file
|
||||
-q quick start (skip configuration interface)
|
||||
--help display this help and exit
|
||||
|
||||
documentation
|
||||
- manpages updated (Volker)
|
||||
|
||||
- configuration file (bochsrc)
|
||||
- there are several new options:
|
||||
config_interface: select text mode menus or wxWindows for configuration
|
||||
display_library: select which display lib to use
|
||||
optromimage: load optional rom images
|
||||
ataN (N=0,1,2,3): up to 4 ATA controllers for hard disks, cdroms
|
||||
ataN-master, ataN-slave, N=0,1,2,3: defines a hard disk or cdrom
|
||||
floppy_bootsig_check: control the 0xaa55 signature check on boot floppies
|
||||
logprefix: lets you change the format of log messages
|
||||
debugger_log: log all output from bochs debugger
|
||||
user_shortcut: allow you to type key combinations like Ctrl-Alt-Del
|
||||
pit: control the PIT model, including realtime option to try to
|
||||
keep in sync with real time.
|
||||
- since v1.3 we've been able to use environment variables in pathnames
|
||||
in the bochsrc file. Now, a few variables have default values, set at
|
||||
compile time, that are used if the user does not set a value. If Bochs
|
||||
is installed correctly, the defaults will be correct and the user will
|
||||
not need to override them.
|
||||
- $LTDL_LIBRARY_PATH is the path name where the plugins can be found.
|
||||
The default value comes from $(plugdir) in the makefile. (This is only
|
||||
important if plugins are enabled.)
|
||||
- $BXSHARE is the path where the BIOSes and keymaps are installed.
|
||||
The default value comes from $(sharedir) in the makefile. Disk
|
||||
images on the Bochs website will begin to use BIOS pathnames like
|
||||
$BXSHARE/BIOS-bios-latest.
|
||||
- new option to reset all settings to initial defaults (Volker)
|
||||
|
||||
- CPU
|

- speed optimizations (Kevin)

|

- minor changes to most of the floppy commands
|

- the status of the 'disk changed' line depends on the selected drive.

wxWindows
|
||||
- wxWindows is a cross-platform C++ user interface library which you can
|
||||
download for free at http://wxwindows.org. wxWindows provides C++
|
||||
classes for all sorts of GUI controls (buttons, menubars, etc.) and
|
||||
implements all of them using the native controls on the platform.
|
||||
- The wxWindows port of Bochs provides both a graphical configuration
|
||||
interface (for editing bochsrc options) and a display. It was
|
||||
written by Bryce Denney, Don Becker, Dave Poirier, and Volker Ruppert.
|
||||
- In release 2.0, we concentrated on making the wxWindows port as stable
|
||||
and functional as the other interfaces. wxWindows provides a great
|
||||
toolbox that we can use to make Bochs easier to learn and use.
|
||||
- To compile Bochs with wxWindows, you should install wxWindows 2.3.3
|
||||
or later. Then configure Bochs with --with-wx.

|

- "display library" is a new term in release 2.0. In the gui directory,
|

Bochs has a number of different C++ files which you can choose from to

display the text and graphics on the simulated monitor. Each of these

display libraries such as SDL which have a full screen mode can be

dangerous, if Bochs does not switch back to normal display mode at

the right time. This is fixed for SDL and the new svga.

it's child windows simulation window and toolbar window.
