H132485 - SYSTEM HANGS OR DEVICE DRIVER WON'T BIND TO NETWORK PROTO. SYMPTOM: The system hangs or device driver won't bind to network protocol. PROBLEM ISOLATION AIDS: The affected system: IBM PC Server 520, Model 8641-EZX, with the IBM Auto 16/4 Token-Ring ISA Adapter, FRU P/N41H8452. FIX: 1. Install IBM Auto 16/4 Token-Ring ISA Adapter in the first available EISA/ISA expansion slot. 2. Run the LANAID utility (included with the adapter) to configure the adapter for Plug and Play mode, making sure Lock Current Resources option is not selected. 3. Run EISA Configuration Utility to update EISA configuration database with resources for this adapter. Ignore the resources reported in the EISA Configuration Utility (since these values are maintained automatically via Plug and Play). Due to a BIOS problem, this adapter runs only in 8-bit mode. This problem will be fixed in a subsequent release of the BIOS. Feb 1, 1996
