Recently purchased brand new Radius Reply Dos Card on Ebay still in box.-Pentium 133 mghz. Installed 12" card into G4 400mghz. The result was a black monitor. Double checked all connections and Apple System Profiler recognized card but had no name for it just a manufacturers number. What went wrong? I need a DOS/MAC Card genius to get me out of this predicament. I assume there is still a DOS card community out there.
