Syntax error fixes:
[x] fixed error with array bounds in virt_timer.cc
[x] fixed error with returning value from void functions
[x] fixed const class member initialization (according C++ standard)
[x] for-loop local variable declaration moved out of loop
(for VC 6.0 compliance)
Removed already committed patch from Dirk Thierbach
Replaced the patch from Vitaly Vorobyov by set of splitted patches.
Now any of his patches could be committed separatelly from others !
[x] fixed bug in int01 (opcode 0xF1) emulation
[x] fixed bug in x86 debugger with dr0-dr3 registers
Committed disassembler bugfix from Dirk Thierbach:
[x] fixed bug in relative addresses in Jmp, Jcc, Call and so on
- installation instructions for FreeDOS Beta 8 added
- sb16 section: description of SB16CTRL.EXE improved
- description of the user shortcut feature updated
This is necessary for devices with different i/o port masks.
- BX_MAX_IO_DEVICES increased to 30
- io_len mask fixed and unnecessary io_len checks removed in
* biosdev.cc
* cmos.cc
* dma.cc
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
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
