- implementation of the UIP bit using a new timer handler. The one_second_timer()
function only sets the UIP bit and starts the UIP timer. The uip_timer()
function handles the date / time update, the alarm check and finally clears
the UIP bit.
- writing to control register A doesn't change the UIP bit
palette - it's an index to the attribute controller palette index.
The new function get_actl_palette_idx() now returns the real DAC index.
The guis sdl, wx and x11 are using the new function. TODO: Fix this bug in
all other guis.
things up for MacOSX, and I don't want to risk that right now just before
the release. I changed it to #if BX_WITH_MACOS to be safe.
(Bochs makefiles currently define -Dmacintosh on OSX. Maybe they
shouldn't but I'm not going to change it right now.)
be zero. I changed it to #ifdef macintosh.
- removed extern "C" {} that only encompassed two #defines. If there
were any includes in there it would be important, but there weren't.
* missing VBE support added, use xmax / ymax variables instead of the
values 640 / 480
* use the constant Y_TILESIZE when checking the y position
* variable vga_mem_updated was always set twice
This version is a bit of a hack that needs to be cleaned up before release.
There is also a glaring bug that lets things go WAY too fast when
we're trying to catch up to real time. This is my highest priority
right now.
register values to a new timeval after date/time change. There is only a
BX_ERROR for now.
- added separate cases for the alarm time registers and a BX_DEBUG message that
reports the new alarm time.
unsigned 64-bit integer and 64-bit double precision floating point. It
knows how to convert Bit64s to double, but it refuses to convert Bit64u
to double. The macros: F2I converts from floating point to integer, and
I2F converts the other way, using Bit64s as a transition step.
F2I: double -> Bit64s -> Bit64u
I2F: Bit64u -> Bit64s -> double
. read port 0x70 (cmos) : return index
. atapi function 46 and 4a : return error
- put back the log prefix for cmos that disappeared when we did the plugins
to make Bochs compile on DJGPP.
- put references to SIGSTOP and SIGTSTP in #ifdefs
- add definition of BX_CD_FRAMESIZE and CD_FRAMESIZE
- look for curses functions in -ldcurses
Modified Files:
gui/term.cc iodev/cdrom.cc configure.in configure
- moved ne2k presence check to devices.cc
- added special make rules for the ne2k and the lowlevel network support
- added macro for the debug feature of the ne2k
For a whole lot of configure options, I put #if...#endif around code that
is specific to the option, even in files which are normally only compiled
when the option is on. This allows me to create a MS Visual C++ 6.0
workspace that supports many of these options. The workspace will basically
compile every file all the time, but the code for disabled options will
be commented out by the #if...#endif.
This may one day lead to simplification of the Makefiles and configure
scripts, but for the moment I'm leaving Makefiles and configure scripts
alone.

For years we have been writing beyond the end of this array in the VGA code:
bx_bool vga_tile_updated[BX_NUM_X_TILES][BX_NUM_Y_TILES];
and doing who-know-how-much damage to other memory structures in the process.
I changed every reference to vga_tile_updated[][] into calls to two macros
GET_TILE_UPDATED and SET_TILE_UPDATED, and defined the macros to check
the bounds of the array before referencing it. At first I used an
assert, then a panic, then an error, and now I'm not printing any message
at all because there were thousands and thousands of messages during
a boot of win95 when it's updating the win95 logo screen.
- I couldn't resist cleaning up a few confusing-looking things like
"if (condition) { // }". There are no functional changes except for
bounds checking on the vga_tile_updated array.
