If it works in cfg with a specific cios, it should also work in gx with the same cios. The problem is not the cios, it may be your config files for gx that are messing up. Delete them and let gx create new ones, you will lose all of your current settings though. HERE is a great guide for updating gx, I dont know if you went from v1 to v2 of gx. If you did, perhaps that is the issue. Either way, that guide directs you to the config files I am referring to.
