1 Windows NT 3.51 v1.03 Windows NT* 3.51 installation notes for Intel's EtherExpress(TM) PRO/100B LAN Adapter ========================================================================= LOCATION OF DRIVER: \NT\E100B.SY_ (NDIS 3 compressed) \OEMSETUP.INF General Instructions -------------------- After putting the adapter in the computer, you need to configure it under Windows NT. 1 Double-click the Network icon in the Control Panel. 2 Click the Add Adapter button. 3 Do NOT select an Intel adapter from the list. Instead, scroll to the end of the list and select: <Other> Requires disk from manufacturer. 4 Click the Continue button. 5 Insert the Intel Configuration and Drivers Disk into your floppy drive and click OK. 6 Select "Intel EtherExpress PRO/100B PCI Adapter (TX or T4)" and click OK. 7 The Intel PROSet Setup program automatically scans computer resources and determines the settings assigned to your adapter. It also adds an Intel PROSet icon to the Control Panel for future use of PROSet. 8 Click the Test button in the Intel PROSet program to run diagnostics. If you've just added the adapter, the network driver won't be active and the diagnostics will test the adapter and its connection to the network. If you're testing an adapter that's already been installed, the network driver will probably be active and the diagnostics will test the driver. This diagnostic tracks the driver's actual network activity. 9 Click OK to exit the test screen and return to the Intel PROSet main menu. 10 Click OK to accept the adapter's configuration and exit the PROSet Program. 11 Click OK in the Network Settings dialog. Other configuration screens may appear. Configure as desired. When prompted, restart Windows NT. Note: The NDIS 3 miniport driver will automatically get installed in Windows NT 3.51. 12 Repeat the General Instruction process for installing additional adapters. ADAPTER SETTINGS There are two ways to run PROSet, which allows changing the adapter settings. - From the Control Panel double click on the Intel PROSet icon. - From the Network Settings screen highlight the Intel PRO/100B adapter and click Configure. From the main Intel PROSet menu click the Change button to get to the Adapter Settings screen. The defaults work correctly for most configurations. Network Speed ------------- Recommended setting: Auto (default) This parameter lets the EtherExpress PRO/100B adapter know what speed to use on the Ethernet wire. The choices are 10 Mbps, 100 Mbps, and Auto. In Auto mode, the adapter detects if its environment can support 100 Mbps speed. It then sets the speed to 100 if it can, or 10 if it can't. If you are using a cross over cable connected to another adapter, set the speed to either 10 Mbps or 100 Mbps. Note: If the Duplex Mode is not set to Auto, then set the speed to either 10 Mbps or 100 Mbps. DUPLEX MODE (100BASE-T4 does not support full duplex) ----------- Recommended setting: Auto (PRO/100B TX adapter only) Auto: The adapter negotiates with the hub how to send/receive packets, either full or half duplex. The PRO/100B T4 adapter does not support auto-negotiating. Full duplex: The adapter sends and receives packets at the same time. This improves the performance of your adapter. Set duplex mode to full duplex only if you have a full duplex switch. Half duplex: The adapter performs one operation at a time. It either sends or receives. A regular adapter can perform only one operation at a time (half- duplexing). The PRO/100B TX adapter has the ability to send and receive packets at the same time (full-duplexing) at both 10 and 100 Mbps. The PRO/100T4 adapter only supports full duplex at 10 Mbps. In order to reap the benefits of full duplexing, you MUST have a full duplex hub. The PRO/100B adapter has the added ability to "talk" to the hub and determine at which mode to communicate (either full or half duplex). This is called auto-negotiation. You must have an auto- negotiating switch to get full duplex support with the Duplex Mode set to Auto. If you don't have an auto-negotiating hub and want to run at full duplex, set Duplex Mode to Full and then set the SPEED parameter to either 100 Mbps (PRO/100B TX) or 10 Mbps (PRO/100B TX or T4). Note: If you set duplex to Full, and leave Speed at Auto, the adapter will run at 10 Mbps. 2 Click the Advanced button in the Adapter Settings screen to change the Advanced setting. Note: The defaults work correctly for most configurations. Please use caution when changing these parameters. Use the on-line help for additional information. COALESCE BUFFERS ---------------- Recommended setting: 8 RECEIVE BUFFERS --------------- Recommended setting: 16 TRANSMIT CONTROL BLOCKS ----------------------- Recommended setting: 16 ADAPTIVE TRANSMIT THRESHOLD --------------------------- Recommended setting: On This parameter dynamically optimizes the point at which early transmit cycles will be executed. This results in higher performance but may generate an occasional underrun. To eliminate underruns, set it to OFF. ADAPTIVE TECHNOLOGY ------------------- Recommended setting: On Adaptive Technology customizes the PRO/100B adapter to the respective operating system by downloading microcode to the silicon. This improves performance and minimizes CPU utilization. MAP REGISTERS ------------- Recommended settings: PCI: MapRegisters = 8 (default for NT 3.5) PCI: MapRegisters = 64 (default for NT 3.51 or later) * Third-party trademarks are the property of their respective owners.Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
