4d6a88ec94 Fixed dbg_fetch_mem() and dbg_set_mem() similar to other memory access methods.
- 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.

plugins compilation.

c12c8324dc Added config parameter to set up advanced PCI options as comma-separated
values. Now it is possible to disable ACPI or HPET in case the i440FX chipset
is selected.

6692664a3b Added helper function bx_split_option_list() to reduce code duplication.
It creates an array of strings from a string containing a comma separated list
of options. Now using this function for display library options, USB port
options and ROM image options.

1ae98a9f66 Unified code for mapping PCI slot to device number. By default the first slot
is mapped to device number #2, but for the i440BX chipset we are using #8
(expected by real BIOS when testing and some timer later added support for it
in Bochs BIOS).

11318c98f3 Improved flash memory support for the BIOS EEPROM (now emulating Intel(tm)
flash chips.
- 28F001BX-T for 128k BIOS image (two 4k parameter blocks below boot block)
- 28F002BC-T for 256k BIOS image (two 8k parameter blocks below boot block)
- Only tested updating ESCD by external BIOS images. Bochs BIOS currently
  writes configuration to shadow RAM.

aaf8c9d4e4 Removed "svga" display library designed for the obsolete Linux SVGALib.
The latest release is from 2001 and it will not work on modern Linux systems.
Parts of the SVGALib code have been moved to the Linux kernel and the X11 and
SDL libraries are using it as a video driver.

d357de7baf Some work on the term gui.
- Now cursor can appear in two different modes (if supported by terminal)
- Simplified text cursor handling.
- Show a status bar if terminal has enough lines for it. Added "show IPS" output
  there unless display library option "hideIPS" is used.

db02efc65f Some small changes in the floppy emulation.
- Reading data register without result present returns the last byte of the
  previous result and enters result phase just like an invalid command.
- Changed name of bit #7 of MSR to RQM (from spec) and some small cleanups.

45507705bf Implemented new text update API in the X gui and some related fixes.
- The X gui behaviour should be unchanged.
- RFB / vncsrv: cursor shape fixes.
- Changed format of the font parameters to fix "double width" characters.
- Restore guest charmap after leaving gui console.

b94fff0501 Implemented new text update API in the vncsrv gui and console cursor fix.
- Now the vncsrv gui supports the VGA features split screen and h/v pel panning.
- Fixed new API cursor blinking in the gui console.

6202244991 Implemented a new text update API in the common gui code and enabled it for RFB.
- Now using text_update_common() for the new text update API in addition to the
  graphical text snapshot feature.
- Drawing to snapshot buffer moved to new method draw_char_common().
- A gui using the new text update API only needs to implement the new method
  draw_char(). The method set_font() is optional and it can be used to update
  font bitmaps / pixmaps.
- Modified the RFB gui to use the new API. Now the VGA features split screen
  and h/v pel panning are supported by the RFB gui. The legacy text_update()
  method is now empty but it must be present for compatiblity.
- TODO: Implement new API in some other guis to reduce code duplication.

0c24af112d Fixed two issues found with valgrind: Since runtime parameters are revoved by
the destructor, the main parameters must be removed after deleting device object.

691461df4d Some work on the flash memory emulation for the BIOS ROM EEPROM. According to
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.

b91f907a1c Some BIOS ROM related changes in the memory code.
- 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.

2293308afe BIOS ROM write support requires a suitable flash memory emulation for the
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.

bab68dbb2b Some small changes on the Voodoo Banshee emulation.
- Access to VGA registers via Banshee address space is not memory mapped.
- Added BX_ERRORs for unimplemented unaligned access to i/o registers.
- Access to the unimplemented YUV address space now causes BX_ERROR.
- Removed some TODO comments.

2045ead0ce Improved error handling of the user shortcut feature.
- Shortcut parser sets a flag in case of error.
- String parameter handler resets to old value if the new one is invalid.
- User button handler shows a message box if the parser signals an error.

1d0efc734f Some work on the Voodoo Banshee emulation.
- New attempt to fix the host-to-screen bitblt issue with monochrome source.
  The specs are wrong at this point. The rules for calculating the real source
  pitch are still unknown. These hacks should fix most the glitches.
- Added source colorkeying support for host-to-screen blt with pattern.

49f8624898 Some changes in the Bochs BIOS.
- Disable i/o and memory access in PCI command register before probing and
  setting up base addresses and re-enable it when complete for selected device.

98e10e0bab Some changes in the Voodoo code.
- Banshee: Added colorkey support for host-to-screen blts without pattern.
- Clearing base address registers in reset is not okay. Maybe we have to
  unregister i/o and memory regions here. This affects other devices, too.
- Some other small changes and typo fixes.
