Hi, you actually have to do the following modification modifications. First you have to modify the function au1100fb_setcolreg, add the switch case for 4bpp. Look in the Alchemy manual for the format of the palette in the 4 bpp case. Then look for my comment "TODO: 8bbp", put a switch and for pseudocolor like visual ... I think this is not even necessary. More important is that you change the monitor type. If you want I can send you privately a patch this weekend, but I just cannot assure it works, you have to test it and eventually contribute. -- Christian <c.pellegrin@xxxxxxxxxxx>
