OK, I am still fighting with my G4 equipped with an Gigadesigns 1,4 GHz G4. I cannot find problems reproduceable at any OS, just 9 has problems (Linux not). So I belive in the meantime that Giga Designs upgades do not work with native Mac OS 9.

If you can, please proove me wrong. Has anyone a Giga Designs running correctly with Mac OS 9?
