If you don't have "PnP OS" set, and the card doesn't get resources assigned, this means that there's a resource conflict that prevents the card from being configured. > how can i solve this problem?? one way out is to have the driver assign > physical addresses to map the pci space. however for that i need the > physical map...what data structure holds that?? Either turn "PnP OS" off, or fix the card/system.
