* register_state() will be called after init() and registers the device members
required for save/restore
* before_save_state() can do some work before the device state is saved by the
siminterface
* after_restore_state() can do some work after the device state has been
restored (updating dependant stuff)
- BM-DMA base address set to 0xc000 at reset (shoud be done by the PCI BIOS)
- BM-DMA status register write messages changed to BX_DEBUG
- fixed an MSVC warning in the harddrive code
#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
* 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
Unallowed cases are now handled in devices.cc and cause a BX_ERROR.
- io_len mask fixed and unnecessary io_len checks removed in
* devices.cc
* extfpuirq.cc
* gameport.cc
* ne2k.cc
* pit.cc
* pit_wrap.cc (i/o register function calls replaced by DEV_* macro calls)
- TODO: implement this in all other devices
and improved by Christophe Bothamy and Volker Ruppert)
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.
palette - it's an index to the attribute controller palette index.
The new function get_actl_palette_idx() now returns the real DAC index.
The guis sdl, wx and x11 are using the new function. TODO: Fix this bug in
all other guis.
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.

- moved ne2k presence check to devices.cc
- added special make rules for the ne2k and the lowlevel network support
- added macro for the debug feature of the ne2k
"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.
