Driver Installation - for Windows for Workgroups v3.11
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(1) Introduction:
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
This document describes the procedure to install Microsoft
Windows for Workgroups v3.11 driver for 10/100 Base-TX PCI
Bus Ethernet Adapter.
(2) Location of Driver:
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
\WFW311\DC21X4.386
(3) Setup Procedure:
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
After you run into Windows for Workgroup 3.11:
1. Select the "Network Setup" icon in the Network Group.
2. Click on the "Drivers..." button.
3. If you are replacing a previous LAN adapter select the Remove
button to delete that adapter
4. Click on the "Add Adapter" button.
5. Choose Unlisted or Updated Network Adapter.
6. Insert the adapter driver disk in drive "A" and specify the path
A:\WFW311 for the location of the driver.
7. The driver's [Setup..] option allows the user to change the
following driver's properties:
o BurstLength: Specify the length of the DMA data transfer within
a PCI burst (1dword = 4 bytes)
1_dword
2_dwords
4_dwords
8_dwords
16_dwords (default)
32_dwords
o Bus Number: Specify the PCI Bus Number the adapter is plugged in.
Should be modified only for adapter plugged over a PCI
to PCI bridge.
0 (default)
1
2
o ConnectionType: Specify the selected Media port
AutoSense Senses dynamically the media ports
100BaseTx To connect 100BaseTx Ethernet hubs
100BaseTx Full_Duplex To connect 100BaseTx Full Duplex hubs
10BaseT To connect 10BaseT Ethernet hubs
10BaseT Full_Duplex To connect 10BaseT Full Duplex hubs
o PciMechanism: Specify the mechanism access to the PCI
configuration space.
AutoDetect Detect the system's PCI mechanism
automatically
Mechanism 1 Force PCI mechanism #1 accesses to the
PCI configuration space
Mechanism 2 Force PCI mechanism #2 accesses to the
PCI configuration space
o ReceiveBuffers: Specify the size of the receive buffer's ring
8 .. 64 (default 16)
o StoreAndForward = REG_DWORD { 0 | 1}
Select the StoreAndForward mode if a low PCI
bandwith causes Transmit Underruns
CSR6<SF> 1 StoreAndForward mode
o 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
8. Click [Close] and [OK] to complete the driver installation.
9. Shutdown and reboot the system so that changes take effect.
Note: If the adapter not work fine after installation, try to
adjust TransmitThreshold and ReceiveBuffers.
(4) Sample PROTOCOL.INI:
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
Windows for Workgroups creates the PROTOCOL.INI for you. This is
provided for reference. This is a sample with Microsoft Netbeui and
IPX/SPX Compatible Transport with Netbios.

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.
