I'm trying to get an AMR modem to work with my GigaByte GA-7DXR motherboard. So far, I've tried two different cards, Epox EP-S56MR and Archtek/Smartlink 56MRC. The Epox is a jumperless design, while the Archtek has jumpers to select the primary and secondary modes. The Epox is not seen by W98SE and the Archtek is recognized, but does not function after being installed. I have no configurable jumpers on the motherboard that I can alter for the AMR slot.
