Driver installation for Microsoft Windows NT 3.51
-------------------------------------------------
1) In the Main group of NT, select the Control Panel icon.
2) In the Control Panel window, select the Network icon.
3) In the Network Settings dialog box, select 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 this driver disk in drive A. Enter drive and pathname A:\
and click the OK button.
6) In the Select OEM Option dialog box, the follwoing adapter name is
displyed. Select this adapter and click the OK button to install it.

7) The Accton EN2220/EN2225 Card Setup dialog box appears. You should
specify the correct values of these parameters for EN2220/EN2225 to work.
Check the section on "EN2220/EN2225 NDIS 3.1 Driver Parameters for
Windows NT" for more information about how to configure the parameters.
8) The system copies ACCNDIS.SY_ from the \WINNT directory on the driver
disk to C:\WINNT\SYSTEM32\DRIVERS\ACCNDIS.SYS, and the OEMSETNT.INF
from \WINNT to C:\WINNT\SYSTEM32 but gives it another name
(e.g. OEMNAD??.INF). If you remove the EN2220/EN2225 driver and would
like to re-install it later, you do not need the driver disk again.
In the above we assumed C:\WINNT is the directory where the Windows NT
system files are installed.
9) To complete network installation, remember binding the adapter to
transport drivers by selecting the "Bindings" button under the Network
Setting dialog box.
10) Insert the Accton EN2220/EN2225 card in one of the CardBus sockets.
Attach the coupler to the back of the card, and connect a cable from the
RJ-45 connector at the back of the coupler to a hub or switch.
Note if you are attaching to a 100 Mbps network, the cable has to
be CAT-5 grade.
You can now shutdown and restart the computer. Please note that during
Windows NT initialization, EN2220/EN2225 must be properly connected to a
hub or switch; otherwise the card and driver would not come up correctly.
Driver installation for Microsoft Windows NT 4.0
------------------------------------------------
1) From Windows NT desktop, double click on "My Computer",
"Control Panel", and "Network" icons.
2) In the "Network" window, click the "Adapters" tab, and the "Add"
button. In the "Select Network Adapter" window, click the "Have
Disk" button.
3) Insert the Accton EN2220/EN2225 Driver Disk in the diskette drive.
4) In the "Insert Disk" dialog box, enter the diskette drive path
name, i.e. A:\ (or B:\), and then click OK.
5) In the "Select OEM Option" box, select "Accton EN2220/EN2225 Fast
Ethernet CardBus PC Card", and then click the OK button.
6) When the "Accton EN2220/EN2225 CardBus PC Card Setup" window shows up,
you have to set up the EN2220/EN2225 configuration parameters as
described in the next section. When you are done, click the
OK button.
7) In the "Network" window, click the Close button. Windows NT then
goes through a binding process. When this process is complete,
Windows NT prompts you to restart the computer. Click on the
Yes button.
8) Insert the Accton EN2220/EN2225 card in one of the CardBus sockets.
Attach the coupler to the back of the card, and connect a cable from the
RJ-45 connector at the back of the coupler to a hub or switch.
Note if you are attaching to a 100 Mbps network, the cable has to be
CAT-5 grade.
You can now shutdown and restart the computer. Please note that during
Windows NT initialization, EN2220/EN2225 must be properly connected to a
hub or switch; otherwise the card and driver would not come up correctly.
EN2220/EN2225 NDIS 3.1 Driver Parameters for Windows NT
------------------------------------------------
1) Connection_Type:
Specify the attached medium type. Default is AutoSense.
2) I/O_Port:
Specify the starting address of I/O port range.
The default value is D000.
3) Memory_Base_Address:
Specify the starting address of the Shared Memory range.
The default value is D0000.
4) Interrupt_Number:
Specify the IRQ number.
The default value is IRQ 11.
5) Socket_Number:
Specify the socket number in which an EN2220/EN2225 is inserted.
The default value is "Auto detect".
6) Interrupt_Style:
Specify the CardBus bridge interrupt routing strategy.
Default is "PCI-IRQ-Routed".
7) Interrupt_Routing:
Specify which interrupt pin is used while the CardBus
bridge is using "PCI-IRQ-Routed". Default is "INT A".
8) Store_And_Forward:
Setting this parameter causes the NIC to disable
the transmit data pipeline operation. Default is "ON".
It is extremely important to assign correct values for the
"Interrupt_Number" (IRQ value) and "Interrupt_Style" parameters.
If the system uses the "PCI-IRQ-Routed" interrupt style, it is also
important to assign the correct PCI "Interrupt_Routing" value (i.e.
INT A or INT B.)
If in doubt about the values to assign to these parameters, you are
advised to execute the CBOPEN.EXE card enabling program in a native
MS-DOS system first. CBOPEN.EXE displays the IRQ value used, as well
as the system's interrupt style. For the Windows NT driver, you should
assign the same values to the above parameters as those displayed by
CBOPEN.
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.
