DOCUMENT:Q105999 03-NOV-1993 [W_NT] TITLE :Err Msg: Nbf Could Not Find Adapter \Device\IbmTok01 PRODUCT :Windows NT PROD/VER:3.10 OPER/SYS:WINDOWS KEYWORDS: ---------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT operating system version 3.1 - Microsoft Windows NT Advanced Server version 3.1 ---------------------------------------------------------------------- SYMPTOMS ======== If an IBM Token Ring card is incorrectly configured for the data rate of the network (16 Mbps or 4 Mbps), the following error messages may appear when you view the System Log in Event Viewer Nbf could not find adapter \Device\IbmTok0x Nbf failed to bind to adapter \Device\IbmTok0x where "x" is the adapter number of your card. CAUSE ===== These messages do not reflect an error in Windows NT. The event log reports that it is unable to find the IBM Token Ring card. When the Token Ring card is initialized, the driver attempts to tell the ring that it is there. If the card is configured incorrectly for the ring, it is unable to communicate to the ring, and therefore tells Windows NT that the card is not present. RESOLUTION ========== Correctly set the jumpers on the card for the data rate of the ring. Switch 12 of the switch block on the IBM Token Ring card sets the rate. For a Data Rate of 16 Mbps, set switch 12 to OFF. For a Data Rate of 4 Mbps, set switch 12 to ON. For additional information on configuring the IBM Token Ring network adapter, call IBM technical support at (800) IBM-9397.
