I. Special Considerations
==========================
To configure the cable media, to change to full-duplex mode
(with a full-duplex hub), or to run Diagnostics, use the
CardAssistant setup program, SETUP24.EXE. The SETUP24
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 "III. Removing
an Existing Driver".
II. Installing the Miniport Driver
==================================
The Windows Miniport (NDIS) driver supports Windows NT 3.5
or later. If you are running version 3.1, you can either
upgrade your copy of Windows NT or download the 3.1 driver,
AT2450.SYS, from the ATI web site; the URL is
http:\www.alliedtelesyn.com.
For 32-bit ODI support with NT 3.5 or later, use the
AT2450.LAN driver in the NWSERVER directory on the
CardAssistant diskette. Note the change in Step 5 of the
installation procedure.
Note: For installations with multiple adapter cards,
complete the installation process for each card. See
"V. Binding a MAC Address to a Protocol".
1. If the AT-2450 adapter card is already installed, reboot
into Windows NT. If you have not installed the AT-2450
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. NT 3.5x: Open the Main program group by double-clicking
its icon.
NT 4.0: Double-click the Network icon in the Control
Panel.
3. NT 3.5x: Double-click the Control Panel icon; double-
click the Network icon. From the Network
box, click Add Adapter.
NT 4.0: Select the Adapters tab; click the Add button.
4. 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.
NT 4.0: From the Select Network Adapter pop-up window,
do not select from the Network Adapter list; choose the
Have Disk button.
5. Insert the CardAssistant diskette into your floppy disk
drive and click OK.
NOTE: For 32-bit ODI support with NT, use the path
<drive>:\NWSERVER, where <drive> is the letter of
the floppy drive.
6. Verify that "ATI AT2450 Ethernet Adapter" appears in the
Choose OEM Option dialog box. Then click OK.
7. In the Network Settings dialog box, verify that "ATI
AT2450 Ethernet Adapter" appears in the Installed Adapter
Cards list. Then click OK.
8. The MAC (Media Access Control) Address dialog box
appears. If this is the only AT2450 to be installed in
the computer, leave the address field blank and click OK
for Auto Scan. Otherwise enter the card's MAC address,
found on the Station Address label inside the manual
cover, and click OK.
9. This completes the card installation. Click OK. Windows
NT prompts you to configure the protocols you will be
using for network communications.
10. From the Network Settings Change dialog box, click
Restart Now.
11. After the Windows NT operating system shuts down,
restart your computer by turning the power switch off
and on. Do NOT use the reset button or
<Ctrl>+<Alt>+<Delete>.
III. 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. NT 3.5x: From the Main program group, choose "Control
Panel". Then choose "Network".
NT 4.0: Double-click the Network icon in the Control
Panel.
2. NT 3.5x: From the "Network Settings" dialog box, select
the adapter to remove. Then choose "Remove".
NT 4.0: Select the Adapters tab. 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 and the
DOS BIOS message appears, reboot your computer by
turning the power switch off and on. Do NOT use the
reset button or <Ctrl>+<Alt>+<Delete>.
6. Log on to Windows NT.
7. Follow the New or Additional Installation section of
this file to install your AT-2450 Ethernet Adapter.
IV. For New or Additional Installations
=======================================
1. NT 3.5x: From the Main program group, choose "Control
Panel". Then choose "Network".
NT 4.0: Double-click the Network icon in the Control
Panel.
2. From the "Network Settings" dialog box, choose "Add
Adapter".
3. 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 choose "Continue".
NT 4.0: From the Select Network Adapter pop-up window,
do not select from the Network Adapter list; choose the
Have Disk button.
4. Insert the CardAssistant diskette into a floppy drive
and then, in the "Insert Disk" dialog box, click OK.
5. Verify that "ATI AT2450 Ethernet Adapter" appears in the
"Select OEM Option" dialog box. Then choose "OK".
6. In the "Network Settings" dialog box, verify that "ATI
AT2450 Ethernet Adapter" appears in the "Installed
Adapter Cards" list. Then choose "OK".
7. From the "Network Settings Change" dialog box, choose
"Restart Now".
8. After the Windows NT operating system shuts down and the
DOS BIOS message appears, reboot your computer by
turning the power switch off and on. Do NOT use the
reset button or <Ctrl>+<Alt>+<Delete>.
V. Binding a MAC Address to a Protocol
======================================
NOTE: By default the AT2450 driver auto-scans the PCI bus
to find the cards. Explicitly binding a MAC address
to a protocol is for installations of more than one
card. The following section explains how to make our
driver scan by MAC address.
1. From the Main program group, choose "Control Panel".
Then choose "Network".
2. From the "Network Settings" dialog box, select the
network card you want to configure, then choose
"Configure".
3. From the "ATI AT2450 Ethernet Adapter Card" dialog box,
enter the MAC address of the card you selected in
step 2. Then choose "OK".
4. From the "Network Settings" dialog box, choose "OK".
5. From the "Network Settings Change" dialog box, choose "
Restart Now".
6. After the Windows NT operating system shuts down and the
DOS BIOS message appears, reboot your computer by
turning the power switch off and on. Do NOT use the
reset button or <Ctrl>+<Alt>+<Delete>.
NOTE: After configuring multiple cards, if NT resets while
booting, you have entered an incorrect MAC address.
To recover from this condition boot DOS, and Change
Directory to the directory containing your NT system
files (e.g. C:\WINNT35\SYSTEM32\DRIVERS). Delete the
driver AT2450.SYS. Reboot NT and reconfigure with the
correct MAC address.

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.
