Using the Controller Diagnostics Utility (Revised 5/2/97)
Copyright 1997 Compaq Computer Corp. All rights reserved.
-----------------------------------------------------------------
-----------------------------------------------------------------
Compaq Diagnostics allows you to verify that your network
controller is functioning properly. The diagnostics may also
identify a potential conflict with the settings on another
controller installed in the computer.
Diagnostics can perform three tests on the controller:
1. Register Test reports whether components on your controller
are working correctly.
2. Internal Loopback Test verifies transmit and receive
functions on the controller by returning the transmitted
signal back to the controller internally.
3. External Loopback Test verifies transmit and receive
functions of the controller by returning the transmitted
signal back to the controller through a loopback plug. This
test simulates the controller being attached to a hub.
The Diagnostics External Loopback Test screen specifies the
type of loopback plug that will work if you are using an RJ-
45 connector; a part number is specified to help you order
it.
System Requirements
- The computer must have 530K of free memory.
- The computer must not be running in protected mode (i.e.,
cannot be running Windows, EMM386, or other memory
managers). You can, however, run HIMEM.SYS and drivers
needed for a mouse.
-----------------------------------------------------------------
Running the Diagnostic Tests
To prepare for testing:
1. Make sure the computer is not connected to the network.
2. Reboot your computer in DOS.
3. Insert your diskette into the floppy drive, and change to
the \DIAG subdirectory.
4. Type DIAG to start the diagnostics program.
5. Before you begin the tests, select View Network Controller
Information to verify that your Compaq controller has been
properly identified. If you do not see the controller you
installed, try these corrective procedures:
- Re-seat the controller in its slot.
- Move the controller to another slot.
- If the computer supports disabling slots on the PCI bus
through the CMOS setup, make sure that the target slot is
not disabled.
If the controller still does not appear when you select View
Network Controller Information, contact your reseller or
Compaq Technical Support.
Testing the controller:
1. Run Quick Check Diagnostics to test the controller's
components.
2. Select Automatic Diagnostics if you want to run the test
suite continuously or for a specified number of times.
3. Choose Interactive Diagnostics if you want to run one or
more of the following individual tests for a single time:
- Register Test: verifies that the controller's
components are working
- Internal Loopback Test: checks the transmit and receive
paths on the controller
- External Loopback Test: requires a loopback plug to
simulate traffic external to the controller as if it
were attached to a network cable
- All of the Above: runs each of the previous tests
If any of these tests fail, you will be advised of the test
and the specific failure. See Troubleshooting for
troubleshooting help.
-----------------------------------------------------------------
Troubleshooting
Verify that you have installed your controller correctly. If you
still receive an error message, take the following steps:
- If you are running the External Loopback Test, check that
the loopback devices are firmly connected and that it is the
type specified on the Diagnostics External Loopback Test
screen.
- Verify that the controller is not touching any other
controller.
- If the computer contains an ISA bus in addition to the PCI
bus, check for an IRQ conflict between a controller on the
ISA bus and the PCI bus.
- (dual-ported controllers only) Check the computer
manufacturer's documentation to make sure that your
computer's BIOS supports PCI-to-PCI bridge technology.
- Try moving the controller to another slot or another
computer.
If the problem persists, see the README.TXT file for instructions
on contacting Compaq Technical Support.
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.
