Please read the documentation at https://parisc.wiki.kernel.org/index.php/Debian_Ports_Installation especially this part: - Installation of a C8000 workstation needs to happen via serial console since the install image will not activate the ATI graphics card. - After installation the ATI cards will work in non-accelerated mode though. I'd suggest to just plug the graphics cable and keyboard cable, and then install via serial port (that works, I did it on my C8000 machines). > > Q3.
