Driver Support and Configuration
Obtaining Drivers for Windows NT 3.51
Due to the age of the hardware, driver support for the 3com 3c905-tx on Windows NT 3.51 is limited to legacy sources. Typically, the drivers are included on the original driver disks provided by 3Com or can be found in archived driver repositories. The specific driver package is called "3Com EtherLink XL for NT" and supports various models, including the 3c905-tx.
Important: Always verify the driver version for compatibility with your specific hardware and operating system build.
Installing and Updating Drivers
- Use the Network Adapter Properties dialog in Windows NT 3.51 to update or reinstall drivers.
- For optimal performance, ensure you select the latest available driver version compatible with Windows NT 3.51.
- In some cases, you might need to manually edit configuration files or registry entries to resolve driver issues.
Configuring Network Settings
Once drivers are installed, configure the network:
- Set a static IP address or enable DHCP, depending on your network setup.
- Adjust speed and duplex settings if needed, although auto-negotiation is usually enabled by default.
- Test the connection by pinging other network devices or accessing shared resources.
