This parameter defines the file name for the flash BIOS config space loaded
startup if existing and saved on exit if modified. The Bochs BIOS doesn't
use this feature yet. Updated 'romimage' option documentation.
These changes only have an effect when using a BIOS image designed for
real hardware (tested with asus_p6np5.bin). When using Bochs BIOS no
data will be saved / restored, since the 'flash_modified' value is
always set to 'false'. Saving ESCD data on exit is not implemented yet,
but it shouldn't be hard to do.
- bx_shadow_filedata_c: using tmpfile64() (same as memory code).
- memory parameters: minimum value set to -2 (means "swapped out").
- FIXME: restore issues still not fixed.
- bx_shadow_bool_c: removed unused bitnum feature and changed data type.
- Changed return type of memory handlers to bool.
- Modified virtual timer, PIC and PIT code.
- Always apply the A20 setting to the requested address.
- Fixed the conditions for SMRAM access.
- Added support for memory handlers and removed direct VGA memory access.
- Added support for reading from BIOS flash memory.
the flashrom project a JEDEC chip needs to be emulated here. Tests with BIOS
images designed for the i440FX chipset are okay, but for the i440BX chipset
some more commands need to implemented.
- Store BIOS ROM start address and use it instead of hardcoded BIOS_MASK.
- Added stub for BIOS ROM access switches.
- Verify checksum of legacy Bochs BIOS, too.
selected PCI chipset. When testing Bochs with a real BIOS image the programming
sequence for the ESCD unexpectedly overwrites some BIOS locations and it fails
to reboot. For the i440BX AGP chipset development it is required to test with
a real BIOS image, but currently reporting "unknown flash type". For now I have
added two stubs with unmodified behaviour.
- Bochs BIOS: Improved calculating PCI slot number from device number to handle
the i440BX case correctly.
- Memory code: Detect and modify the PCI IRQ roouting table of the Bochs BIOS
for the i440BX chipset (TODO: this could be done by the BIOS itself after
copying to shadow RAM).
- Fixed PCI BAR initialization (now using memset()).
- Fixed reset failure (set all PAM memory types to ROM).
- Added stub for the AGP aperture (register BAR #0, handle APSIZE and read
GART entry in read/write handlers).
- Added some more PCI register defaults and write masks.
- Fixed a warning in the ES1370 code.
- Voodoo Banshee: set up PCI subsystem ID depending on bus and model.
- Volatile BIOS write support must also be present in ISA BIOS memory.
- Added support for setting memory write handler to NULL (ROM case).
- Added new PCI device method after_restore_pci_state(). It currently handles
the PCI ROM case only (could be extended).
configuration, loading images). Cleaned up "romimage" option parsing and
prepared parameter "options" for the behaviour of the Bochs BIOS.
TODO: implement BIOS option "fastboot" to skip the boot menu prompt.
- added Android case to the configure script.
- renamed file memory.h to memory-bochs.h to fix conflict with NDK.
- fixed Android issues in some files.
