I have upgrade my Mac OS 8.1 to OS 9.1 and reintalled the PC compatible on the new OS 9.1. Everything seem to be working fine except I have not been able to get the networking to work. If I disable the NIC card from the PC side, the PC card with win98 boot up fine, but as soon as I installed the NDIS PC card driver, the PC card hung. Any help would be appreciated.
