Installation Guide for the Windows NT 3.51 Driver
----------------------------------------
You should install your adapter before installing your
network driver.
Your network operating system should be installed before you
install the network driver.
Windows NT 3.51
----------------------------------------
The eMASTER+ diskette driver supports Windows NT version
3.51. For a Windows NT driver that supports Windows NT
version 3.50, download 350PCI.EXE from any of Cogent's
electronic forums. Both of these drivers use the same
installation procedure, described below.
The Windows NT 3.51 driver and help file for Intel-based
computers is in WINNT\i386; for Alpha-based computers it is
in WINNT\ALPHA.
Windows NT 3.51 for MIPS and PowerPC Platforms
----------------------------------------
The Windows NT driver for MIPS platforms is available for
the EM960 and EM960 Combo adapters.
The Windows NT driver for PowerPC platforms is available for
the EM110 T4 PCI, EM110 T4 PCI Combo, EM110 TX PCI, and
EM110 TX PCI Combo.
These drivers can be obtained from Cogent's electronic
forums, or by contacting Cogent Technical Support.
To Install and Configure the Windows NT 3.51 Driver
----------------------------------------
Follow the instructions below to install the Windows NT
driver for your Cogent PCI adapter.
1. In Control Panel, double-click the Network icon.
2. Choose Add Adapter.
3. From the Add Network Adapter dialog box, choose
the <Other> option, which is at the end of the
list of displayed adapters.
4. Specify the path to your eMASTER+ adapter
diskette. The Windows NT 3.5x driver for Intel-
based computers is in WINNT\i386; for Alpha-based
computers it is in WINNT\Alpha.
5. One driver supports all eMASTER+ PCI adapters for
Windows NT 3.51. For Windows NT 3.50, choose your
adapter from the list provided.
6. When prompted, choose your cable type from the
displayed list. For Full Duplex operation, select
"AUTOSENSE/Full Duplex." Otherwise, accept the
default of "AUTOSENSE/Half Duplex."
7. Choose OK.
8. After Windows NT restarts, you will be able to use
your new eMASTER+ adapter.
Port Binding Sequence for Quartet Adapters
----------------------------------------
When installing a Quartet adapter under Microsoft NT, the
binding sequence of each port is important. Protocols such
as TCP/IP rely on specific protocol addresses to be mapped
to specific ports. Windows NT may place port bindings in non-
sequential order during initial driver installation. This
can be corrected through the Control Panel.
1. Choose Networks icon from within the Control
Panel.
2. Choose Bindings from the Network Settings windows.
3. In the Network Bindings window, select "Cogent
EMPCI Adapter Driver" from the "Show Bindings for"
pulldown menu.
4. In the bindings window, highlight any of the
driver instances and use the Up and Down ordering
buttons until the drivers are ordered 1 through 4
(or the last port, if a multiple adapter
configuration) from top to bottom.
5. Save the settings, exit out of Networks and
Control Panel, and restart your system for the
changes to take effect.
Network Interface Parameters
----------------------------------------
To reconfigure your adapter's cable type after you have
already installed your eMASTER+ adapter, go to Control
Panel/Networks. Highlight your adapter in the "Installed
Adapter Cards" window, and choose from one of the following
options:
----------------------------------------
INITSENSE/Half Duplex
Performs cable type and line speed autodetection at adapter
initialization (startup) time.
----------------------------------------
INITSENSE/Full Duplex
Performs cable type and line speed autodetection at adapter
initialization (startup) time with Full Duplex operation
enabled.
----------------------------------------
ACTIVESENSE /Half Duplex
Performs cable type and line speed autodetection at
initialization (startup) time and at regular intervals
during runtime. Use only when a cable is attached to
adapter.
----------------------------------------
ACTIVESENSE/Full Duplex
Performs cable type and line speed autodetection at
initialization (startup) time and at regular intervals
during runtime, with Full Duplex operation enabled. Use only
when a cable is attached to adapter.
----------------------------------------
THIN
Sets the adapter's cable type to BNC (also known as THINNET
or 10Base-2) cable. (Combo models only)
----------------------------------------
10 Mbps
Selects for 10 Mbps UTP operation. (10 and 10/100 models
only)
----------------------------------------
10 Mbps/Full Duplex
Selects for 10 Mbps UTP Full Duplex operation (10 and 10/100
models with RJ-45 only)
----------------------------------------
100 Mbps
Selects for 100 Mbps UTP operation. (100 and 10/100 models
only)
----------------------------------------
100 Mbps/Full Duplex
Selects for 100 Mbps UTP Full Duplex operation (100BASE-TX
models only)
Other Configuration Parameters
----------------------------------------
The Windows NT application REGEDT32.EXE gives you access to
other eMASTER+ PCI configuration parameters. Use
REGEDT32.EXE only if you are familiar with the Windows NT
Registry. Run REGEDT32.EXE and go to
SYSTEM\CURRENT_CONTROL_SET\SERVICES\EMPCI1\PARAMETERS\. The
following configuration options are available:
----------------------------------------
fp_off
Optimizes driver performance on some machines. Do not use
with the Intel 430FX PCI motherboard chipset (which includes
Intel chips with the following part numbers: 82437FX,
82438FX, 82371FB, 82438FX). Set this parameter to "1" to
activate optimization.
Default: 0 (disabled)
Range: 0, 1
----------------------------------------
BurstLength
Determines Packet Burst Length (the maximum number of DWORDs
to be transferred in one DMA transaction).
Default: 32 DWORDS
Range: 1 DWORD, 2 DWORDS, 4 DWORDS, 8 DWORDS,
16 DWORDS, 32 DWORDS
----------------------------------------
IPG
Compatibility parameter to be used as directed by Cogent
Technical Support.
Default: 0 (disabled)

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.
