Installing an ATI AT-2560 Series PCI adapter in a PCI slot
==========================================================

1.  With power off, put the adapter in the computer.

2.  Start the computer. In most cases, the PCI computer will automatically
  . configure the adapter. If this doesn't happen, you may have to
   .configure the computer to work with the adapter. See the next section
   .for details.


If you have problems
====================

ATI has found that some PCI computers require additional configuration
to install a PCI adapter. Follow these steps to complete the
installation:

1.  Make sure you have the latest BIOS version for your computer.

2.  Make sure the BIOS is set up correctly.

The following sections describe these steps in detail.


Make sure you have the latest BIOS version
------------------------------------------

Contact your computer's manufacturer to make sure you're using the latest
BIOS. Here are the phone numbers for the top PCI computer manufacturers:

BIOS setup
----------

In some PCI computers, you may need to enable the PCI slot using the BIOS
Setup program. This is especially common in PCI computers with a Phoenix
BIOS.

After installing the adapter, turn on the computer and enter the Setup
program during system initialization (usually by pressing F1, F2, or Ctrl-
Alt-S). The key you press is usually shown on the screen.

Once in Setup, find the entry for PCI slots.  Set these parameters:

PCI Slot#:     Slot where the adapter is installed (1-3)
Master:        ENABLED
Slave:         ENABLED
Latency Timer: 40
Interrupt:     Choose an IRQ.
Edge-level:    Level

The exact wording of the parameters varies with different computers.

Save the changes, exit Setup, and continue with the installation.


Updating the Compaq DeskPRO XL BIOS
===================================

There are two primary steps:

1.  Upgrade the Compaq system BIOS to v2.22E (available from Compaq).

    In general, follow the instructions on page 7-12 (Using the Compaq
    EISA Configuration Utility) in the Compaq "Beyond Setup for the
    Deskpro XL." This includes: Power off, Set switch 6 to ON, Power on,
    Run EISA Config Utility to reconfigure, select computer setup icon,
    select OK to restart, Press F10 with cursor in upper right of screen,
    select System Configuration, wait while computer reconfigures, enter
    to complete, MAKE SURE to set S6 back to OFF position before powering
    off (this disables the erase option).

2.  Upgrade the Compaq Rompaq, and follow the instructions below.

    The Compaq BBS Rompaq upgrade for the DeskPro/XL (SP1022.zip) works
    with the AT-2560 PCI LAN adapters.

    In general, follow the instructions from Compaq, which include setting
    switch S1 to On for update.  (S1 On - disabled:  Flash ROM can be
    updated. S1 OFF - enabled:  Prevents Flash ROM updates. Off is the
    default.)

To correctly enable the card after this BIOS is installed:

1.  On restart, press F10 to go into the configuration utility when the
    blinking cursor moves to the right corner.

2.  The COMPAQ configuration screen should come up.  The BIOS rev. shown
    here must be 2.22E (or later).

3.  Press return to get initial configuration choices.

4.  Press CTRL-A. If a message saying 'Advanced Features Enabled' does not
    appear, you cannot enable the ATI adapter.

5.  Press return to confirm, and then choose Configure system.

6.  After the configuration runs, choose View, Edit Details.

7.  Under the Advanced Features section, look for PCI Master Enable.  The
    default is disabled. Change the setting to enabled.

8.  Further down, in Slot X, you should see PCI Ethernet Controller.  Move
    the cursor to enabled, and press F6 to check the settings.  Typically,
    the ATI adapter will be INT 2(9). Change this to INT 10.

9.  Move down to Embedded PCI Ethernet Controller. The default is enabled.
    Change the setting to disabled.

10. Save settings and exit.
