The colors 0..7 appear in high intensity and the colors 8..15 blink using
low / high intensity. Blinking is not present in Bochs yet. For now, the 3rd
bit of the attribute will be inverted.
- attribute controller mode control register: only a change of the internal
palette size bit should force a redraw
- skip screen update if video is disabled
plane enable and color select
- a screen update is necessary after updating the charmap
- lots of missing parentheses added (found after disabling VGA_TRACE_FEATURE)
- BX_DEBUG and BX_INFO messages improved
- update function: the 'for' loop now initializes and increments the variables
xti and yti
- VBE: banked writes are now ignored in LFB mode, LFB writes are ignored in
banked mode (based on SF patch #742782)
- calculation of the VBE virtual height for >8bpp fixed
- visible screen size must be recalculated after changing the virtual width
- modify standard VGA register when enabling a VBE mode (some test applications
expect this behaviour)
- BX_INFO messages in the VBE code fixed
DEV_kbd_gen_scancode() is called instead of DEV_kbd_put_scancode(). This
change enables the support for different scancode sets. The win32 scancodes
are now converted to BX_KEY_* values (partially copied from gui/win32.cc)
- new text mode features: line offset, cursor size, font height
- key handling rewritten (taken from x.cc)
- headerbar now working
- headerbar colors changed
- graphics modes > 640x480 now cause a BX_PANIC
* configure.in: readline check is only necessary if the debugger is enabled
(patch from Jeroen Janssen)
* iodev/Makefile.in: dependencies updated after adding gameport device
- don't clear the VBE memory if the new flag VBE_DISPI_NOCLEARMEM is set
- vbe_bpp_multiplier for the 4bpp mode set to 1 (usually unused, but this value is save)
(based on a patch from Christopher Nelson <paradox@BBHC.ORG>)
* the win32 gui changes the bitmap settings using the bpp argument
* added stubs for all guis except win32
* descriptions of function dimension_update() updated
font usage)
- horizontal and vertical pel panning in text mode implemented (without windows
fonts only)
- separate bitmap for the textmode cursor no longer necessary
- text_update(): unused variable new_start removed
compile time. The old version used this fonts for char heights smaller 14.
If the Windows fonts are enabled, the font heights 12, 14 and 16 are used.
These features are not available in that case:
* charmap change
* char width switch 8/9
* horizontal and vertical pel panning
If the Windows fonts are disabled, the changeable guest font is used and all
implemented features are available. This is the default setting.
TODO: implement horizontal and vertical pel panning
FIXME: Should we add a bochsrc option to control the font usage?
- invalidate character at previous and new cursor location before entering the
update loop
- cursor drawing moved into the update loop
- variables for previous cursor position renamed
