Installing the DC21X4 Driver on Windows NT: 1. From the Windows NT Main Menu, select the Control Panel icon. 2. From the Control Panel menu select the Network icon. If a dialog box asks you "Do you want to install NT Network?" select YES and Continue. Then place the Windows NT CDROM in the CD-ROM reader. Select the drive that matches the configuration of your system and complete the install. 3. You will see several messages. To add a network adapter, select Yes and then Continue 4. For each additional message, select continue. 5. From the Add Network Adapter dialog box, scroll through the menu to select Other. 6. When the Insert Diskettes menu prompts you for a disk, insert the DC21X4 driver installation diskette for Windows NT into drive A. Type the path A:\WINNT40. Then select OK. 7. Select your option [Digital Semiconductor 21143 based 10/100 mbps Ethernet Controller] from the Select OEM Option box, then select OK. 8. Modify the default distribution path in the Windows NT Setup box to point to the correct drive and path, then click on [Continue] 9. For PCI options, a Dialog box pops up to select the: ConnectionType: o AutoSense Senses dynamically the media ports o 10BaseT (TP) To connect 10BaseT Ethernet hubs o 10BaseT (TP) Full Duplex To connect 10BaseT Full Duplex hubs o 10BaseT (TP) No_Link_Test To connect hubs not supporting the Link Integrity Test o 100BaseTx (TP 100) To connect 100BaseTx Ethernet hubs o 100BaseTx (TP 100) FDx To connect 100BaseTx Full Duplex hubs 10. Upon completion, the selected adapter is added to the Installed Adapter Cards list of the Network Setting box (the number prefixing the adapter is the adapter number). 11. Click on [Close] to complete the Network Setting initialization. 12. If needed, modify the values in the registry (see section 7 below). 13. Shutdown and reboot the system. B. Parameters To overwrite the initial values set by the EISA Configuration Utility (ECU) or overwrite the driver's default values, add or edit the following values in the Registry DC21X4<adapter_number> Parameters subtree: CacheLineSize = REG_DWORD { 16 | 32 | 64 | 128 } 16 bytes 32 bytes (default) 64 bytes 128 bytes ExtraReceiveBuffers = REG_DWORD {value} (default: 16) Number of buffers allocated by the driver in the Receive look_aside list. ExtraReceivePackets = REG_DWORD {value} (default: 100) Number of packets preallocated by the driver. InterruptMitigation = REG_DWORD {0 | 1} 0 Disabled (default) 1 Enabled Enable/disable the Interrupt Mitigation algorithm. InterruptThreshold = REG_DWORD {value} (default: 500) Maximum number of interrupt/second allowed before the Receive and Transmit interrupts get masked. Meaningfull only when InterruptMitigation is enabled. FrameThreshold = REG_DWORD {value} (default: 400) Minimum number of processed frame/second allowed before the Receive and Transmit interrupts get unmasked. Meaningfull only when InterruptMitigation is enabled. MemoryReadMultiple = REG_DWORD { 0 | 1 } 0 Disabled (default) 1 Enabled Enable/disable PCI Memory_Read_Multiple command. MRM should be enabled when the DC21X4 is connected to the TI1130 PCI/CardBus bridge. ReceiveBuffers = REG_DWORD {8..64} (default: 16) Number of buffers allocated by the driver in the Receive ring. UnderrunRetry = REG_DWORD number_of_retries (default=2) Maximun number of retransmission attempts of an underrun packet. UnderrunThreshold = REG_DWORD number_of_underruns (default=10) Maximun number of underrun occurences before the controller switches to the next threshold value. The following values allow to overwrite the DC21X4 default setting. Refer to the Digital Semiconductor 21143 10/100 mbps Ethernet Controller Engineering specifications for detailed description: BackPressure = REG_DWORD { 0 | 1 } CSR6<BP> 0 Disabled (default) 1 Enabled BurstLength = REG_DWORD { 0 | 1 | 2 | 4 | 8 | 16 | 32 } CSR0<PBL> 0 unlimited (default) 1 doubleword 2 doublewords 4 doublewords 8 doublewords 16 doublewords rev1) 32 doublewords CaptureEffect = REG_DWORD { 0 | 1 } CSR6<CA> 0 Disabled (Default) 1 Enabled FifoArbitration = REG_DWORD { 0 | 1 } CSR0<BAR> 0 Rcv/Txm Arbitration (default) 1 Round_Robin SnoozeMode = REG_DWORD { 0 | 1 } CFDA<SM> 0 Disabled (default) 1 Enabled StopBackoffCounter = REG_DWORD { 0 | 1 } CSR6<SB> 0 Disabled (Default) 1 Enabled StoreAndForward = REG_DWORD { 0 | 1 } Select the StoreAndForward mode if high PCI latencies causes 100Mbps Transmit Underruns CSR6<SF> 1 Enabled 0 Disabled (default) TransmitThreshold = REG_DWORD { 72 | 96 | 128 | 160 } Transmit Threshold values for 10Mbps media.

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.
