Basically, there is no port i/o on a non-intel system, the PCI i/o space will be memory-mapped. By the way, the ATI Rage II graphics chip can of course do 1024x768 at 16 bpp with 2MB video memory. Even i f Sun's X-Server did not support it, a port of XFree will. Best regards, Sebastian Lederer -- Sebastian Lederer lederer@bonn-online.com
