I. Special Considerations
=========================
The AT-2500TX supports autonegotiation. If the connected
device does not support autonegotiation, you must select
the port settings. In this case, refer to the "Connection
speed and duplex" information file.
Configuration of the AT-2500TX resources is under PCI
control. For most applications, no setup other than normal
installation of the network software is necessary. To
change port settings, to manually view the card's
configuration or to run Diagnostics, use the CardAssistant
setup program, SETUP25.EXE.
The SETUP25 utility only runs on DOS. If you do not have
a DOS boot partition on your Windows NT drive, boot DOS
from floppy.
To de-install the driver, use the remove driver option from
your Windows NT Network Control Panel. See "IV. Removing
an Existing Driver".
II. Files Needed for Installation
=================================
The following files are required for installation:
\A25v3m4.SYS (NDIS4 driver)*
\OEMSETNT.INF (OEM setup file for NT 4.0 and greater)
\NDIS3\A25v3m.SYS (NDIS3 driver)*
\NDIS3\OEMSETNT.INF (OEM setup file for NT 3.51)
\INFO\WINNT.TXT (this file)
*NOTE: Use the NDIS3 driver for Windows NT version 3.51.
Use the NDIS4 driver for Windows NT 4.0 and greater. If
you are running version 3.1, you must upgrade your copy
of Windows NT. (You can check the Windows release
number in the System Properties dialog box, General tab.)
III. Installing the Miniport Driver
===================================
If you are installing multiple adapter cards in a single,
computer, complete the installation process for each card.
1. If the AT-2500 adapter card is already installed, reboot
into Windows NT. If you have not installed the AT-2500
adapter card into your computer, shutdown the computer,
turn it off and unplug it. Install the card by following
the instructions that came with your computer. Then turn
the computer on again. Boot into Windows NT.
2. Double-click the Network icon in the Control Panel.
3. NT 4.0: Select the Adapters tab; click the Add button.
From the Select Network Adapter pop-up window,
do not select from the Network Adapter list;
choose the Have Disk button.
NT 3.5x: From the Network Adapter Card drop-down list in
the Add Network Adapter dialog box, choose
"<OTHER> Requires Disk from Manufacturer." Then
click Continue.
4. NT 4.0: Insert the CardAssistant diskette into your
floppy disk drive; make sure a:\ appears in the
text field and click OK.
NT 3.5x: Insert the CardAssistant diskette into your
floppy disk drive; type "a:\NDIS3" in the text
field and click OK.
5. Verify that "ATI 2500 Fast Ethernet card" appears in
the Choose OEM Option dialog box. Then click OK.
6. In the Network Settings dialog box, verify that "ATI
2500 Fast Ethernet" card appears in the "Installed
Adapter Cards" list. Then click OK.
7. This completes the card installation. Click OK. Windows
NT prompts you to configure the protocols you will be
using for network communications.
8. From the Network Settings Change dialog box, click
Restart Now.
IV. Removing an Existing Driver
===============================
If any drivers need to be removed from your existing
installation, remove them first, shutdown the NT operating
system and reboot.
1. Double-Click the Network icon in the Control Panel.
2. NT 4.0: Select the Adapters tab. Select the adapter to
remove. Then choose "Remove".
NT 3.5x: From the "Network Settings" dialog box, select
the adapter to remove. Then choose "Remove".
3. From the "Network Settings" dialog box, verify that the
selected adapter has been removed from the "Installed
Adapter Cards" list. Then choose "OK".
4. From the "Network Settings Change" dialog box, choose
"Restart Now".
5. After the Windows NT operating system shuts down, turn
the power switch off and on.
6. Log on to Windows NT.
7. Follow the "New or Additional Installation" section of
this file to install your AT-2500 Fast Ethernet Adapter.

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.
