2. You must now use my function to set or get any palette
registers.This means that the keywords "3c7", "3c8", and "3c9" should not even exist in your code.I really
didn 't want to force you to use my palette functions, but
since VESA 2.0 supports non VGA compatible cards, you must
do
it this way.If you use setbrightness for all of your
palette setting, then you can ignore this.Note that the
palette format here is VESA 's palette format, which is
different than my other palette control functions.It 's
4 bytes and RGB are backwards.Here are the function
prototypes:
VBE_setPalette(int palstart, int palnum, char *dapal);
VBE_getPalette(int palstart, int palnum, char *dapal);
palstart is the offset of the first palette to set
palnum is the number of the palette entries to set
dapal is a pointer to the palette buffer.The palette
buffer must be in this format:
char Blue, Green, Red, reserved;
I think this format stinks, but since VESA 2.0 uses
it, the code will run fastest if the buffer is not
copied.You can make your own cover up function if
you don 't like this format.
This example sets up a wasteful gray scale palette:
char mypalette[1024];
for (i = 0; i < 256; i++)
{
mypalette[i * 4 + 0] = (i >> 2); // Blue
mypalette[i * 4 + 1] = (i >> 2); // Green
mypalette[i * 4 + 2] = (i >> 2); // Red
mypalette[i * 4 + 3] = 0; // reserved
}
VBE_setPalette(0, 256, mypalette);
