--------------------------------------------------------------------------------
1 Overview
This README file explains how to use the program DosDiag.exe to test
your network adapter or to maintain the Flash PROM contents of the adapter.
Chapter 2 contains a list of all network adapters that are supported by
this program.
Chapter 3 describes the command line options that can be used when
starting the Diagnostic program.
Chapter 4 explains how to use the Diagnostic program to test your network
adapter.
Chapter 5 explains how to use the repeater mode.
2 Supported Adapters
The program DosDiag.exe supports the 3Com 3C2000-T Gigabit
Ethernet Adapter.
3 Command Line Options
The following lists shows the optional parameters supported by DosDiag.exe.
You can obtain a list of all available driver options by typing the
following:
DosDiag -?
Parameters specifying the network adapter to be tested
------------------------------------------------------
-b <bus> PCI Bus number
-d <dev> PCI Device number of the network adapter
-y <ven> Additional PCI Vendor Id to search for
-z <dev> Additional PCI Device Id to search for
Parameters influencing the tests to be made
-------------------------------------------
-l List all supported adapters installed
-t <seconds> Set Time Limit (in seconds)
-a Advanced mode of operation. This option should only
be used if instructed by technical staff!
-o <file> Generate an output file
-x Create/append an output file. The file name is
generated by taking some bytes of the MAC address.
-c <file> Generate a script file. This option should only be
used if instructed by technical staff!
-p <file> Generate a parameter file. This option should only
be used if instructed by technical staff!
NOTE: The length of the file name <file> is limited to 13 characters.
4 How to use the Diagnostics Program
In order to test your adapter, proceed as follows:
1. Start the DOS-based utility program DosDiag.exe using any of
the available options to correctly specify the network adapter
if required.
NOTE: The options '-b', and '-d' may be combined as required in order to
specify exact the network adapter which is to be tested.
All specified options are checked against the network adapters list.
You may also force a list of all installed 3Com Gigabit Ethernet
adapters by using the '-l' option.
2. Select the action you want to carry out.
If the network adapter is to be tested, three options are available:
- "Diagnostics",
- "Loopb. Wrap Plug" and,
- "Loopb. Port to Port".
"Diagnostics":
Select this option if no wrap plug or port-to-port loopback
cable is available.
"Loopb. Wrap Plug":
To run tests in this mode, another station must be connected to the test
station in repeater mode before this test starts.
NOTE: Wrap plugs are not available for 1000BASE-T adapters.
Please connect another station in repeater mode instead.
For further information on the repeater mode, refer to the next section.
"Loopb. Port to Port":
This test mode is recommended for dual port adapters.
To run tests in this mode, both ports taking part in the test
must be connected through a cable before this test starts.
Other dual link adapters may also be tested through a port-to-port
loopback cable. Single port adapters cannot be tested this way.
3. If you intend to maintain your Flash PROM contents
select the menu item "Flash PROM ...".
A new menu will appear.
Now, you may
- save your Flash PROM contents to a file
("Save Flash PROM to File")
- write a file into the Flash PROM
("Load Flash PROM from File")
- erase your Flash PROM contents
("Clear Flash PROM").
4. If you intend to maintain the VPD Data contents
select the menu item "VPD Data ...".
The VPD menu will appear.
Now, you may
- display the adapter's VPD data
("Display VPD Data")
- clear error log entries
("Clear Error Logs")
- modify VPD data
("Add/Modify VPD Data")
- remove VPD keywords
("Delete VPD Keywords").
NOTE: During the adapter tests, the diagnostic program must have
exclusive rights to use that network adapter. All drivers
running on the adapter will be stopped!
5 How to use the Repeater Mode
The repeater mode is intended to simulate a 'Wrap Plug' while
1000BASE-T adapters are tested. For running a "Loopb. Wrap Plug" test,
the device under test must be connected to an adapter running in
repeater mode before the test starts.
Although the repeater mode is available for fiber adapter, too, it is
not advisable to perform diagnostics loopback tests with a repeater
station because the link establishment for fiber adapter is different
and is not fully implemented in the diagnostics loopback tests.
To enable the diagnostics repeater mode, proceed as follows:
1. Choose the option 'Repeater Mode' from the main menu.
2. Select a port number.
The repeater window appears. All incoming frames except pause frames
are looped on the transmit side without modifications.
The following table shows the configuration parameters and
statistic counters displayed in the repeater mode window.
parameter/counter start value description
---------------------------------------------------------------------------
Link State Down The link state may be down or up.
If up, frames can be received and
transmitted.
---------------------------------------------------------------------------
Link Master/Slave Slave This parameter indicates if the
Config adapter is working as master or
as slave.
The parameter is only supported
for 1000BASE-T adapters.
---------------------------------------------------------------------------
Link Estimate 1E-15 This parameter indicates the
the estimated link error rate.
This parameter is only supported
for 1000BASE-T adapters.
---------------------------------------------------------------------------
Link Changes 0 The counter indicates the number
of link operational changes since
the repeater mode started.
---------------------------------------------------------------------------
False Carrier 0 The counter is only valid for
Sense Counter 1000BASE-T adapters and shows the
number of false carrier sense
counters occured since the
repeater mode started.
---------------------------------------------------------------------------
FCS Errors 0 The counter indicates the number
of Frame Check Sequence (FCS) errors
occured since the last link
operational change.
---------------------------------------------------------------------------
Frames Received 0 The counter indicates the number
of received frames. Received pause
frames are neglected.
---------------------------------------------------------------------------
Frames Transmitted 0 The counter indicates the number
of transmitted frames. Transmitted
pause frames are neglected.
---------------------------------------------------------------------------
Pause Frames Received 0 The counter indicates the number
of received pause frames.
---------------------------------------------------------------------------
Pause Frames 0 The counter indicates the number
Transmitted transmitted pause frames.

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.
