====================================================
Location of driver: \NWSERVER\A2560.LAN
\NWSERVER\A2560.INF
General instructions for NetWare* Client 32 under Windows 95
============================================================
1. Install the adapter in the computer and turn on the power. Have the
Windows 95 CD ROM available, as you will need it to copy additional
files. While Windows 95 is starting, it will detect the new hardware.
NOTE: Step 2 assumes Client 32 is not already installed. If it is,
the NEW HARDWARE FOUND dialog box will show the 2560 and the ODI driver
will be installed.
2. When Windows 95 starts, a NEW HARDWARE FOUND dialog box appears. It
identifies the adapter as a PCI Ethernet Controller. In the Select
Device dialog box, click the "Have Disk . . ." button.
NOTE: If the NEW HARDWARE FOUND dialog box doesn't appear, you'll
need to manually configure the adapter. See the section on
alternative ways to add a network adapter to Windows 95.
3. Insert the CardAssistant disk in drive A and click OK.
4. A dialog box prompts for a location. Enter "a:\nwserver". (You can
also use the NDIS 3 driver; in this case enter "a:\".) Click OK.
5. In the Select Device dialog box, make sure "ATI AT-2560FX PCI
Ethernet Adapter (ODI)" is shown. Click OK.
6. A dialog may appear requesting NetWare Client 32 files. If so, follow
the instructions.
7. A dialog may appear requesting Windows 95 system network files. If
so, follow the instructions.
8. The Systems Setting Change dialog appears indicating you should
restart the system for changes to become effective. Remove the
adapter disk from the drive and click Yes for the changes to
take effect.
Installing A2560SET adapter diagnostic and configuration software
-----------------------------------------------------------------
The A2560SET software allows you to test the adapter in the Windows 95
environment. It can also resolve some Windows 95 issues that may result
from changing or updating adapter hardware.
1. From the Explorer, double click on the 3.5 floppy disk icon. The
Explore function can be accessed by clicking on the Windows 95 Start
button with the right mouse button.
2. Locate the A2560SET icon in the root directory of the diskette and
click the right mouse button. From the menu that appears, click
Install.
3. When the A2560SET software has been copied to your computer, go to
the control panel and click on the A2560SET icon. A2560SET examines
your computer and displays the A2560SET Window. This window shows
the adapter's I/O address, interrupt and Ethernet address.
Note: The adapter's interrupt is set by the computer's BIOS. If you
have to change the interrupt, some computers allow you to change this
setting, and some don't. Check your computer's documentation for
details. A2560SET will inform you of any problems with the current
setting.
4. Click Test to begin diagnostics.
Advanced Configuration Parameters
---------------------------------
The defaults work correctly for most configurations. Please use caution
when changing these parameters. To make a change, follow the steps
listed below.
Note: Be sure to use A2560SET to configure these settings rather than
the Advanced Configuration tab under Properties. Since this driver
also supports all 82557-based adapters, some parameters have
different values depending on which adapter is installed. A2560SET
will display the proper values for the adapter you are configuring.
The Properties screen may not.
1. Double-click on the A2560SET icon located in the Control Panel.
2. Click on Change button.
3. If the AT2560 will be communicating with a full-duplex hub,
change the duplex option on the Basic Settings menu.
4. Click on Advanced.
5. For the highlighted Property on the left, the Value is displayed on
the right.
Duplex Mode - Default Setting: Half-Duplex
A performance option that lets you choose how the adapter sends and
receives packets over the network. A regular adapter can perform only
one operation at a time (half-duplexing). The AT-2560 PCI adapter has
the ability to send and receive packets at the same time (full-
duplexing). In order to reap the benefits of full duplexing, you MUST
have a full duplex hub.
Half Duplex: The adapter performs one operation at a time. It
either sends or receives.
Full Duplex: The adapter sends and receives packets at the same time.
This improves the performance of your adapter. Set duplex
mode to full duplex ONLY if you have a full duplex hub.
Coalesce Buffers - Recommended setting: 8
Number of memory buffers available to the driver in case the driver
runs out of available Map Registers. This packet area is also used
when a packet consists of many fragments.
Map Registers - Recommended Setting: 64
Map registers are system resources used in physical to virtual
address conversion with bus mastering cards. The Map Registers
parameter specifies how many registers should be allocated to the
driver.
Receive Buffers - Recommended setting: 16
Specifies the number of buffers used by the driver when copying data
to the protocol memory.
Transmit Control Blocks - Recommended setting: 16
Specifies how many transmit control buffers the driver allocates for
adapter use. This directly corresponds to how many outstanding
packets the driver can have in its "send" queue.
Speed - Setting: 100 Mbps
This parameter lets the adapter know what speed to use on
the Ethernet wire. The speed is fixed at 100 Mbps.
Alternatives for adding network cards to Windows 95
---------------------------------------------------
Windows 95 automatically detects Plug and Play devices when they are
added to the system, and either loads drivers for the new device, or
prompts the user for the location of the drivers. However, this feature
does not work the same on all computers and with all cards.
This text provides alternatives for adding drivers for newly
installed hardware. One of these should work in cases where the general
instructions above don't work.
Some of these methods arrive at the same dialog boxes, but yield
different results because of the path taken.
Control Panel ... SYSTEM (Recommended Method)
--------------------------------------------
1. Double-click My Computer.
2. Double-click Control Panel.
3. Double-click System.
4. Click the Device Manager tab.

7. Click the Driver tab.
8. Click Change Driver.
9. Select Network Adapters and click OK.
10. Click Have Disk, insert the CardAssistant disk
in the appropriate drive, and click OK.
If you get into Device Manager and do not have an Other Devices
icons in the device list, Windows 95 did not detect your card at all.
This condition indicates a problem with the adapter itself, or with
the system BIOS, rather than a Windows 95 Plug and Play problem.

Hints and Tips
--------------
1. Multiple Adapters in Windows 95:
If you have multiple AT-2560 PCI adapters installed in the system, be
sure to install and run A2560SET. It will automatically detect that
you have multiple adapters and update the EID (Ethernet ID) field,
which is required by Windows 95 for card identification.
Background: If multiple network adapters are installed in a Windows
95 system, each card must be identified by the last 8 digits of the
Ethernet address. However, Windows 95 requires decimal numbers which
makes it necessary to perform a hex to decimal conversion. For
example, an adapter with the Ethernet address of 0000F4123456 would
require putting 4094833750 as the Ethernet ID value (F4123456
converted to decimal is 4094833750). Windows calculator, in
scientific mode, is a tool you can use for the conversion if you need
to do the conversion manually.
2. Using Full Duplex:
Installing a driver through Windows sets the driver to Half Duplex.
In order for you to use Full Duplex, you must set it in A2560SET.
You must be connected a Full Duplex hub.
3. Moving adapters to different slots:
When removing a PCI adapter and placing it in a different slot,
Windows 95 retains the old instance of the driver and adds a new one
for the new slot/card combination. This behavior is common to any
adapter. The driver stops functioning when the number of accumulated
old drivers reaches 2 (for a total of 3 installed drivers, including
the current driver). The workaround is to remove the old driver
before changing slots, or to run A2560SET and allow it to associate
the card with the appropriate instance of the driver.
4. Swapping AT-2560 adapters in the same slot.
In order for Windows 95 to properly recognize a different AT-2560
adapter in the same slot, the EID must be updated. This update can
be achieved in a few different ways. Perform one of the following
items for the update to happen.
- The easiest method is to run A2560SET after swapping the adapters.
- Or, remove the adapter by performing a Remove Device in the Device
Manager or Remove Adapter in Network Control Panel. Then, shut
down the computer and install the other AT-2560 adapter.
- Or, shut down the computer, remove the adapter, turn on the
computer and start Windows 95 without any adapter. At this point,
Windows 95 detects that the adapter was removed and deletes the
obsolete registry entries. Shut down the computer, install the
adapter, start Windows 95, and perform a regular adapter
installation.
