- scan for VGABIOS ROM after rombios32 init
- copy PCI ROM to shadow RAM at 0xc0000 and enable it
- NOTE: this feature does not work with BIOS-bochs-legacy, so we should recommend to use the
default BIOS for PCI display adapters
- TODO: load VGABIOS ROM from the vga code instead of main.cc if PCI is disabled
Now the handler receives 'rw' (BX_READ, BX_WRTE, BX_EXECUTE) access type as parameter.
If returning a pointer to <addr> - itr is assumed that whole 4K page containing the <addr> could be accessed using the same pointer with offset.
You can return a pointer for READ/WRITE only and disallow execute, this is handled properly in the CPU code.
Sebastian Herbszt). TODO list:
- modify LGPL'd VGABIOS to make it work with SeaBIOS
- modify Bochs BIOS to set up the legacy address 0xc0000
- implement PCI ROM support in the cirrus device
- move load_ROM calls to the display adapter code to handle the ISA case
environment. As a first step use it to skip some networking module tests.
- link BOCHS.EXE with MSVCRT if MSVC plugin support is enabled (building DLL
plugins with nmake still not possible - VS2008Ex workspace package coming soon)
- updated some messages for NE2000, PCI and USB
environment. As a first step use it to skip some networking module tests.
- link BOCHS.EXE with MSVCRT if MSVC plugin support is enabled (building DLL
plugins with nmake still not possible - VS2008Ex workspace package coming soon)
- updated some messages for NE2000, PCI and USB
support compiles and links fine and the main object files for the plugin DLLs
are created. Since the gui and iodev makefiles are not ready yet, the link
stage must be done manually. Support for the search path defined in
LTDL_LIBRARY_PATH should be added when the DLL plugins compile and work.

* moved runtime handlers for cdrom from config.cc to the device object
* cd media status variable is now always of type bx_bool
* changed obsolete gui names like "cdromD" to "cdrom1"
* TODO: implement new runtime config mechanism similar to USB
each other. Devices can register a handler to update it's state after runtime
configuration. The new method update_runtime_options() executes all registered
device handlers before the simulation continues.
- USB host controllers now using the new mechanism to handle the runtime device
change (replaces the previous timer-based implementation). TODO: floppy and
cdrom could use this feature, too)
- improved USB device change messages
