B) Firmware Requirements : o Fully compliant Rev. 2.0 or above PCI BIOS supplied with the PC. o If the adapter makes use of Digital Semiconductor 21050 (PCI-PCI bridge), PCI BIOS should support PCI-PCI bridge architecture. C) Software Revision Requirements : Windows NT Version 4.0 or later 4) Installing Software ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ A) From the Windows NT Main Menu, select the Control Panel icon. B) 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. C) You will see several messages. To add a network adapter, select Yes and then Continue D) For each additional message, select continue. E) From the Add Network Adapter dialog box, scroll through the menu to select Other. F) When the Insert Diskettes menu prompts you for a disk, insert the DC21X4 driver installation diskette for Windows NT into drive A. Then select OK.

H) Modify the default distribution path in the Windows NT Setup box to point to the correct drive and path, then click on [Continue] I) For PCI options, a Dialog box pops up to select the: ConnectionType: o AutoSense Senses dynamically the media ports o AutoSense_NoNway Senses dynamically the media ports without Nway negotiation o 100BaseTx To connect 100BaseTx Ethernet hubs o 100BaseTx Full_Duplex To connect 100BaseTx Full Duplex hubs o 100BaseT4 To connect 100BaseT4 Ethernet hubs o 100BaseFx To connect 100BaseFx Ethernet hubs o 10BaseT To connect 10BaseT Ethernet hubs o 10BaseT Full_Duplex To connect 10BaseT Full Duplex hubs o BNC (10Base2) BNC connector o AUI (10Base5) 15_pin connector J) 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). K) Click on [Close] to complete the Network Setting initialization. M) If needed, modify the values in the registry (see section 7 below). N) Shutdown and reboot the system. 5) Parameters ÄÄÄÄÄÄÄÄÄÄ 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} (DC21140,DC21142) 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. NetworkAddress = REG_SZ { xx-xx-xx-xx-xx-xx } Mandatory if no Serial ID PROM is plugged in Overwrite the Serial ID PROM if plugged in NetworkAddress 00-00-00-00-00-00 is ignored NwayProtocol = REG_DWORD { 0 | 1 } (DC21041 and DC21142 Rev1.0,1.1 only) 0 Disabled 1 Enabled (default) Enable/disable the 10BT/10BT_FD Nway medium negotiation in Autosense mode. ReceiveBuffers = REG_DWORD {8..64} (default: 16) Number of buffers allocated by the driver in the Receive ring. SoftwareCRC = REG_DWORD { 0 | 1 } (DC21040 rev 1.x, 2.0 & 2.2 only) 0 The CRC is generated by the adapter 1 (default) The CRC is generated by software for transmit packets bigger than the transmit threshold. NOTE: This option affects performances and could be disabled if the adapter does not report transmit underruns in its statistic counters 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) (DC21140 and DC21142 only) Maximun number of underrun occurences before the controller switches to the next threshold value. The following values allow to overwrite the DC21X4 default setting.

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.
