Definitions
===========
Duplexing. A performance option that lets you choose how
the adapter sends and receives packets over the network.
Half duplex. The adapter performs one operation at a
time (because send and receive lines are shared); it
either sends or receives.
Full duplex. (Requires full-duplex switching hub.) The
adapter sends and receives packets simultaneously by
using a different wire to perform each function. This
feature can improve adapter performance by eliminating
collisions.
Warning: Incorrectly forcing a specific duplex mode may
result in poor performance. Consult your LAN
administrator before forcing a duplex mode or if you
don't know what kind of hub you're attached to.
Speed. The AT-2500TX adapter card operates at either
10 Mbps or 100 Mbps. The operating speed must match the
speed of the network segment (link).
NWAY. Method for automatically negotiating optimum speed
and duplex between devices on a link.
Auto/NWAY. The card adapts to the speed of the link. If
connected to an NWAY-capable switch, the devices will
negotiate the best combination of speed and duplex mode.
Works for half-duplex connection with or without NWAY-
capable switch or hub. Does not work for full-duplex
connection unless connected to an NWAY-capable switch.
ATI AT-2500 PCI adapter connection choices
==========================================
Auto/NWAY (default)
-------------------
As shipped, the AT-2500TX adapter card is set up to adapt
to the speed of the link. This is the best setting if the
link is half duplex or if the link supports NWAY.
Manually configuring for full-duplex without NWAY
-------------------------------------------------
If the link is full duplex and does not support NWAY,
manually set up the connection type using the SETUP25
utility on the CardAssistant diskette.
Note that performance may suffer if your hub is not full
duplex and you configure the adapter to full duplex. Leave
the adapter on half duplex if you are not sure what type of
hub you are connected to.
1. Boot the computer into DOS with no drivers loaded. (In
Windows 95, boot into the "Command prompt only" option.
Press the F8 key when the message "Starting Windows 95"
appears, and select "Command Prompt only", which is
Startup menu choice 6.)
2. Insert the CardAssistant diskette in the floppy drive
and launch SETUP25; type "A:\setup25".
3. Use the arrow keys to select the card (if necessary).
Press ENTER.
4. Select Configuration.
5. Use Enter and the arrow keys to select connection.
6. Press F10 to preserve your change.

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.
