configure script option --enable-magic-breakpoints (enabled by default).
Documented the instruction required to trigger the magic breakpoint
(xchgw %bx,%bx).
PNI could be enabled by setting BX_SUPPORT_PNI in config.h
After the feature will be fully validation I'll also add configure option.
The implemntation is ~complete. I've missed only three FPU new opcodes of FUSTTP instruction and MONITOR/WAIT instructions.
Enjoy ! ;)
* support for different resource compilers added (rc / windres)
* bochs must be linked with advapi.lib for registry access
* optimization flag changed to /Ox
* symbols BX_HAVE_MKSTEMP, BX_HAVE_SYS_MMAN_H and HAVE_ETHERTAP must be set to 0
* BX_HAVE_REALTIME_USEC definition fixed for MSVC
* vmware3.h: definition of COW_Header fixed for MSVC
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.
- it works only on x86 with gcc2.95+
- uses the GCC function atribute "regparm(n)" to declare that certain
functions use the register calling convention
- performance improvement is about 6%

Comment from the author:
Attached is a "patch" file detailing what you need to do
to add USB support (UHCI only for now) to your existing
Bochs (2.0.xx) source code.
I use Win32 and VC++ but the source and modifications
should be platform and compiler independant.
Please let me know if this patch some how breaks the
build process of your compilation (Bochs 2.0.0 or above
only).
I would also like any feedback on how this code works
(or doesn't work) on your platform and within your
images. If you explain in as much detail as you can on
how it did or did not work, I will try to add to the source
to help it work on all platforms and images.
- new symbol BX_USE_PCIVGA_SMF for the experimental PCI VGA device
- pcivga.cc: removed unnecessary include statement
- pcivga.cc: fixed two warnings
- pcivga.h: removed unnecessary symbol BX_IODEV_PCIVGA_H
add SVGALIB display library by Igor Popik <igipop@wsfiz.edu.pl>
While it's running, you can press F12 to escape into the runtime config
menu, and then you can change disks or quit or whatever.
Better not try it with the bochs debugger...you could get stuck.

- configure script adds -DBX_PLUGIN_PATH="${plugdir}" to CFLAGS/CXXFLAGS
in the Makefile.
- in main.cc, if plugins enabled and the environment variable LTDL_LIBRARY_PATH
is not set, then it gets set to the value supplied by BX_PLUGIN_PATH.

"bx_bool" which is always defined as Bit32u on all platforms. In Carbon
specific code, Boolean is still used because the Carbon header files
define it to unsigned char.
- this fixes bug [ 623152 ] MacOSX: Triple Exception Booting win95.
The bug was that some code in Bochs depends on Boolean to be a
32 bit value. (This should be fixed, but I don't know all the places
where it needs to be fixed yet.) Because Carbon defined Boolean as
an unsigned char, Bochs just followed along and used the unsigned char
definition to avoid compile problems. This exposed the dependency
on 32 bit Boolean on MacOS X only and led to major simulation problems,
that could only be reproduced and debugged on that platform.
- On the mailing list we debated whether to make all Booleans into "bool" or
our own type. I chose bx_bool for several reasons.
1. Unlike C++'s bool, we can guarantee that bx_bool is the same size on all
platforms, which makes it much less likely to have more platform-specific
simulation differences in the future. (I spent hours on a borrowed
MacOSX machine chasing bug 618388 before discovering that different sized
Booleans were the problem, and I don't want to repeat that.)
2. We still have at least one dependency on 32 bit Booleans which must be
fixed some time, but I don't want to risk introducing new bugs into the
simulation just before the 2.0 release.

constructors around. The min,max that were being passed to the parent
class constructor had junk in them. In config.h.in, I defined the minimum
and maximum values for each integer datatype so now we pass correct
min and max values to the parent class. These replace the BX_MAX_[U]INT
and BX_MIN_[U]INT values.
