This file explains how to install the Windows for
Workgroups driver for x86-based platforms.
80386 or higher microprocessor based computer with PCI bus.
Digital Semiconductor's 21140-based Fast Ethernet PCI adapter or on-board chipset.
Windows for Workgroups Version 3.11 or later
INSTALL.DOC This file.
OEMSETUP.INF The driver's setup file for WFW.
DC21X4.386 The driver's executable.
2. In the Network Setup applet, press the [Drivers...] button.
3. In the Network Drivers applet, press the [Add_Adapter...] button.
4. Select the [Unlisted or Updated Network Adapter] option and click [OK]
5. 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 i386\wfw sub_directory.
6. Select the following adapter from the Network Adapters list:
[DEC PCI Fast Ethernet Digital Semiconductor's 21140
]
7. For PCI adapters, the driver's [Setup..] option allows the user to change the following driver's properties:
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.
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
100BaseT4 To connect 100BaseT4 Ethernet hubs
100BaseFx To connect 100BaseFx Ethernet hubs
10BaseT To connect 10BaseT Ethernet hubs
10BaseT Full_Duplex To connect 10BaseT Full Duplex hubs
BNC (10Base2) BNC connector
AUI (10Base5) 15_pin connector
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
ReceiveBuffers: Specify
the size of the receive buffer's ring 8 .. 64 (default 16)
MapRegisters = REG_DWORD {4,8,16} (default: 8)
SnoozeMode = REG_DWORD { 0 | 1 } (DC21041 only) CFDA<SM>
0 Disabled (default)
1 Enabled
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)
TransmitThreshold = REG_DWORD { 72 | 96 | 128 | 160 }
Transmit Threshold value for 10Mbps media.
CSR6<TTM,TR> 72 bytes
TransmitThreshold100 = REG_DWORD { 128 | 256 | 512 | 1024 }
Transmit Threshold value for 100Mbps media.
UnderrunThreshold = REG_DWORD
number_of_underruns (default=10) (21140 and 21142 only) Maximun
number of underrun occurences before the controller switches to
StoreAndForward mode.
8. Click [Close] and [OK] to complete the driver installation.
9. Shutdown and reboot the system.
10. Installing multiple PCI boards: Repeat the procedure
above.
