NOTE: The system may stop responding on a computer of any bus type. CAUSE ===== This problem occurs on some systems with the following configuration: - Plug-and-Play option is enabled on the 3c509b NIC - Using a driver dated earlier than 2/7/95 RESOLUTION ========== To correct the problem: 1. Download EtherDisk version 4.2 (3C5X9X.EXE) from the 3Com Bulletin Board Service (BBS) at (408) 980-8204 to a blank formatted floppy disk. 2. Extract the file by typing the following at the command prompt: 3C5X9X 3. To correct the PCI Auto-Configuration error, disable the Plug-and-Play feature on the 3C509B NIC by typing the following at the command prompt: PNPDSABL.BAT 4. In order for the operating system to function properly with the 3C509B NIC, replace the existing driver with the driver provided by 3C5X9X.EXE. For example, to replace the 3C509B NIC driver for Windows NT version 3.5, rename the existing ELNK3.SYS driver in the %SystemRoot%\SYSTEM32\DRIVERS subdirectory. Go to the \NDIS\WINNT35 subdirectory on the EtherDisk version 4.2 floppy disk and type the following at the command prompt: COPY ELNK3.SYS :\%SystemRoot%\SYSTEM32\DRIVERS 5. Restart your computer.
