I have a strange problem. I have several Gateway computers (Pentium 100s) that the zero key on the numeric keypad does not function properly in DOS. If you press the zero key five times, perhaps only 1 zero will appear. This happens when using a DOSapplication and it also happens at just a DOS prompt. This is not a case of a bad keyboard because the key works just fine in Windows applications. I have tried using non-Gateway keyboards and that didn’t change anything. Help!
