thanks for links
only something i don't understand:
Code: Select all
3C0h index 0-Fh (R/W): Attribute: Palette
bit 0-5 Index into the 256 color DAC table. May be modified by 3C0h index
10h and 14h.
so, the firsts 16 index entries are reserved for the palette?
there are only 16 colors?
if that, what mode is it?

The 16-color lookup table mentioned is an poorly documented and a hardly used thing. If you keep out of it, colors 0-255 will always map to the corresponding DAC entry. If you're serious about it, read "Graphics Programming Black Book", which documents this feature properly. If you want the default values, send 0 to index 0, 1 to index 1, 2 to index 2 etc.
