Driver Installation - for Windows NT 3.5x ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ (1) Introduction: ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ This document describes the procedure to install Windows NT ver. 3.5x driver for 10/100 Base-TX PCI Bus Ethernet Adapter. (2) Location of compressed Driver: ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ \WINNT35\DC21X4.SY_ \WINNT351\DC21X4.SY_ (3) Driver Installation Procedures for Microsoft Windows NT: ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ 1. In the Main group of NT, select the "Control Panel" icon. 2. In the Control Panel window, choose the "Network" icon. 3. In the Network Settings dialog box, choose the "Add Adapter" button. The Add Network Adapter dialog box appears. 4. In the list of network cards, select "<other> Requires disk from manufacturer", and then press <Enter> button. 5. Insert the driver disk in drive A, enter drive and pathname A:\WINNT35 which is the path where the driver and setup file OEMSETUP.INF are located, and then choose the OK button. 6. A Dialog box pops up to select the followings: ConnectionType: o AutoSense Senses dynamically the media ports supported by the adapter. The precedence 100BaseTx, 10BaseT. o 100Mbps To connect 100BaseT Ethernet hubs o 100Mbps Full_Duplex To connect 100BaseT Full Duplex hubs o 10Mbps To connect 10BaseT Ethernet hubs o 10Mbps Full_Duplex To connect 10BaseT Full Duplex hubs 7. NT will then perform the binding process. If any additional network software options were installed, you may be prompted for specific information for these packages. 8. Restarting your system then you will acquire network service. Note: If the adapter did not work fine after installation, try to adjust TransmitThreshold and ReceiveBuffers. (4). Parameters: ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ ReceiveBuffers = REG_DWORD {8..64} (default 16) Number of buffers allocated by the driver in the Receive ring. MapRegisters = REG_DWORD {4,8,16} (default: 16(alpha) | 8) Number of map registers allocated by the adapter. CacheLineSize = REG_DWORD { 16 | 32 | 64 | 128 } 16 bytes 32 bytes (default) 64 bytes 128 bytes The following values allow to overwrite the DC21X4 default setting. BurstLength = REG_DWORD { 1 | 2 | 4 | 8 | 16 | 32} CSR0<PBL> 1 doubleword 2 doublewords 4 doublewords 8 doublewords 16 doublewords (default) 32 doublewords FifoArbitration = REG_DWORD { 0 | 1 } CSR0<BAR> 0 Rcv/Txm Arbitration (default) 1 Round_Robin StoreAndForward = REG_DWORD { 0 | 1 } Select the StoreAndForward mode if high PCI latencies causes Transmit Underruns CSR6<SF> 1 Enabled 0 Disabled (default) TransmitThreshold = REG_DWORD { 72 | 96 | 128 | 160 | 256 | 512 | 1024 } CSR6<TTM,TR> 72 bytes 96 bytes 128 bytes 160 bytes (default) 256 bytes 512 bytes 1024 bytes StopBackoffCounter = REG_DWORD { 0 | 1 } CSR6<SB> 0 Disabed (Default) 1 Enabled BackPressure = REG_DWORD { 0 | 1 } CSR6<BP> 0 Disabed (default) 1 Enabled CaptureEffect = REG_DWORD { 0 | 1 } CSR6<CA> 0 Disabed (Default) 1 Enabled These Registry values can be edited interactively through the Registry editor (winnt\system32\regedt32.exe) or by invoking the regini command Edit an DC21X4.ini file as described below, then invoke the command: regini DC21X4.ini DC21X4.ini format: \Registry\Machine System CurrentControlSet Services dc21x4_{adapter_number} Parameters {valuename} = {type}{value} (5). Error Messages: ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ The error messages are logged in the Entry Log and can be seen using the Entry Log Viewer (in WNT's Administration Tools group). Each error message has a standard Ndis error code and an driver's additional code. The additional codes are: DC21X4_ERRMSG_REGISTRY 0x01 DC21X4_ERRMSG_ALLOC_MEMORY 0x02 DC21X4_ERRMSG_SROM 0x03 DC21X4_ERRMSG_MEDIA 0x04 DC21X4_ERRMSG_LOAD_CAM 0x05 DC21X4_ERRMSG_SYSTEM_ERROR 0x06 DC21X4_ERRMSG_TXM_JABBER_TIMEOUT 0x07 (6). Driver Initialization Errors: ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ o NDIS_ERROR_CODE_UNSUPPORTED_CONFIGURATION DC21X4_ERRMSG_REGISTRY The AdapterType Registry's key is missing or its value is unsupported by the adapter board o NDIS_ERROR_CODE_ADAPTER_NOT_FOUND No board matching the AdapterCFID Registry's key value was found plugged into the PCI bus or in the slot specified in the Registry o NDIS_ERROR_CODE_OUT_OF_RESOURCES DC21X4_ERRMSG_ALLOC_MEMORY Not enough memory to allocate space for the Adapter data block o NDIS_ERROR_CODE_INVALID_VALUE_FROM_ADAPTER DC21X4_ERRMSG_SROM Invalid data read from the adapter's serial ROM o NDIS_ERROR_CODE_NETWORK_ADDRESS No readable burnt_in or software configured station address o NDIS_ERROR_CODE_UNSUPPORTED_CONFIGURATION DC21X4_ERRMSG_MEDIA The selected media port is not supported by the board. o NDIS_ERROR_CODE_INTERRUPT_CONNECT Interrupt initialization failed o NDIS_ERROR_CODE_TIMEOUT DC21X4_ERRMSG_LOAD_CAM DC21X4 CAM initialization failed (7). Driver Run Time Errors: ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ o NDIS_ERROR_CODE_HARDWARE_FAILURE DC21X4_ERRMSG_SYSTEM_ERROR System_Error interrupt (bus parity error) o NDIS_ERROR_CODE_HARDWARE_FAILURE DC21X4_ERRMSG_TXM_JABBER_TIMEOUT Transmit Jabber timer expiredDownload 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.
