I have a Rage II, I know it works under windows and Damn Small Linux 2.8, I used it with Damn Small Linux on a different PC, and and also with windows on that PC and this PC., the card never gave me any trouble before, well now I have Fedora Core 6 and wanted to do a dual-head setup, but during boot it gave me an error about a PCI device, unkown header 7f, ignoring. Or something close along those lines, I don't have any OS's I can test it on dependably right now, I could perhaps get the latest release of DSL and try it, though. So can anyone help me make it work?
