This file explains how to install the driver onto the Windows
for Workgroups 3.11 system.
3) System Requirement
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
A) Hardware Requirements :
o An IBM-compatible personal computer with 80386 or higher
microprocessor and a PCI bus.
o This adapter.
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 for Workgroups Version 3.11 or later
4) Installing Software
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
A) In the Windows for Workgroups Network Group, open the Network
Setup option.
B) In the Network Setup applet, press the [Drivers...] button.
C) In the Network Drivers applet, press the [Add_Adapter...]
button.
D) Select the [Unlisted or Updated Network Adapter] option
and click [OK]
E) When the Insert Driver dialog box prompts you for a disk,
insert the driver installation diskette into the drive,
press the [Browse...] button and select the WFW311\
sub_directory.
F) Select the adapter that matches your hardware
from the Network Adapters list

G) For PCI adapters, 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
o AutoSense Senses dynamically the
media ports
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
o PciMechanism: Specify the mechanism access to the PCI
configuration space.
o AutoDetect Detect the system's PCI
mechanism automatically
o Mechanism 1 Force PCI mechanism #1
accesses to the PCI
configuration space
o 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 MapRegisters = REG_DWORD {4,8,16} (default: 8)
Number of map registers allocated
by the adapter.
o SnoozeMode = REG_DWORD { 0 | 1 } (DC21041 only)
CFDA<SM> 0 Disabled (default)
1 Enabled
o StoreAndForward = REG_DWORD { 0 | 1} (DC21140 only)
Select the StoreAndForward mode if high
PCI latencies causes 100Mbps Transmit
Underruns
CSR6<SF> 1 Enabled
0 Disabled (default)
o TransmitThreshold = REG_DWORD { 72 | 96 | 128 | 160 }
Transmit Threshold value for 10Mbps media.
CSR6<TTM,TR> 72 bytes
96 bytes (default)
128 bytes
160 bytes
o TransmitThreshold100 = REG_DWORD { 128 | 256 | 512 | 1024 }
Transmit Threshold value for 100Mbps media.
CSR6<TTM,TR> 128 bytes
256 bytes
512 bytes (default)
1024 bytes
o UnderrunThreshold = REG_DWORD number_of_underruns
(default=10) (21140 and 21142 only)
Maximun number of underrun occurences before
the controller switches to StoreAndForward
mode.
H) Click [Close] and [OK] to complete the driver installation.
I) Shutdown and reboot the system.
J) Installing multiple PCI boards :
Repeat the procedure above.
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.
