1.  ACCTEST.EXE - The ACCTON EN2220 CardBus PC Card Testing Program 

ACCTEST.EXE is the EN2220 CardBus PC Card testing program.  This program
runs only under a native MS-DOS system.  It is not recommended to run this
program in a Microsoft Windows or IBM OS/2 DOS box.  Before executing
ACCTEST.EXE, you must execute CBOPEN.EXE, the EN2220 CardBus PC Card
enabler, first.

You can use ACCTEST.EXE to check if EN2220 is working properly in your
notebook computer. ACCTEST.EXE performs the following tests:

   a.  Configuration Test
   b.  I/O Test
   c.  ID Test
   d.  Internal Loopback Test
   e.  External Loopback Test
   f.  Interrupt Test
   g.  Network Function Test

2.   Test Requirements

You must have a notebook computer that is equipped with CardBus sockets.
For some notebooks on the market today, the CardBus sockets are configured
to work in either the 16-bit PCMCIA mode or the 32-bit CardBus mode.
EN2220 works only in the CardBus mode.  Please consult the documentation
that comes with your notebook on how to properly configure the CardBus

You can use a single notebook to test the basic functionalities of EN2220.
However, when conducting Network Function Test, EN2220 sends a stream of
Ethernet packets on the network to test the packet transmission function.
In this case, it is recommended to have a second notebook on the same
network, also with an EN2220 installed and running ACCTEST.EXE, to receive
the packets.  The number of packets transmitted and received and the
performance figure are displayed by ACCTEST.  You can use the two notebook
test configuration to make sure the EN2220 PC Cards, the cables, and other
networking components are all working properly.

3.   Running the ACCTEST Program

Insert an EN2220 CardBus PC Card into a CardBus socket in your
notebook.  Also insert the EN2220 Driver Disk in floppy drive
A:, and type:

	 A:\> CBOPEN   <Enter>
	 A:\> ACCTEST  <Enter>

When ACCTEST starts, it tries to find all EN2220 CardBus PC Cards in the
notebook.  If your notebook does not support PCI BIOS, or there is no EN2220
in the system, the program will display an error message.  Otherwise,
ACCTEST  displays information about all EN2220 cards found.  Each  EN2220's
information consists
of the card number, its Ethernet address, the IRQ used, the I/O port used,
and a predefined medium type (The Auto-Negotiation type indicates the 
medium type is AUTO sensed.)  You can use the UP and DOWN arrow keys to
select the card to test, or use the RIGHT or LEFT arrow keys to select the
medium type.  EN2220 supports the following five medium types:

   1. Auto Negotiation
   2. TP 10Mbps
   3. TP 100Mbps
   4. TP 10Mbps Full Duplex
   5. TP 100Mbps Full Duplex

At this point, you can press the ESC key to exit ACCTEST; or to
press the ENTER key to start the test on the selected PC Card.

ACCTEST begins the test and executes the test items one by one until
it comes to the Network Function Test.  For each test item, ACCTEST
displays either a PASS or FAIL criterion.  If a test item fails,
ACCTEST displays a window at the bottom of the screen
to indicate possible causes for the failure and the recommended
correction procedure.

For Network Function Test, you can use the following three function keys 
to control the test:

  <F1>    To reset all counters 

  <F2>    To toggle the Network Function Test to either ON or OFF.  When
	  the Network Function Test is switched to ON, EN2220 continuously
	  sends Ethernet packets on the network.  Press F2 a second time
	  stops this process.

  <ESC>   To terminate and return to the PC Card selection screen.

The Network Function Test reports these statistics:  Number of packets
transmitted (TX count), number of packets received (RX count), number of
packets with ALG error, number of packets with CRC error, and the
number of collisions.  It also displays how long the test has been
running and a calculated performance figure that shows how many data bytes
are transmitted per second.

4. Suggested solution to failed test items

    Failure Item               Suggested Solution          
   ---------------             -------------------           
   Configuration        1. Make sure the CardBus socket is   
       Test                properly configured to support   
			   CardBus cards.                   
			2. Make sure an EN2220 is properly  
			   inserted and seated in a CardBus 
			3. Make sure you have executed      
			   CBOPEN.EXE before executing      
    I/O Test            1. Check if you are running         
			   EMM386.EXE.  If the  EMM386.EXE  
			   has a version earlier than 4.49, 
			   it can not handle properly       
			   DWORD accesses and may cause     
			   the I/O Test to fail.            
    ID Test             1. Make sure the PC Card is a most  
			   recent version of EN2220.        
   Internal Loopback    1. make sure EN2220 is seated       
	Test               securely in the CardBus socket.  
   External Loopback    1. Check your cables and connectors.
			2. Check if you have selected the   
			   correct medium type.             
			3. Check if you are using a cross-  
			   over cable, if you use cross-    
			   over cable, you may not pass the 
			   external loopback test.          
   Interrupt Test       1. Check IRQ setting in the  PCI    
   Network Function     1. Check that cables, connectors,   
       Test:               hubs are properly connected.     
  Receive Test Fails    2. Re-install the PC Card.          
   (Rx packet count     3. Reset the notebook and run the   
    not running)           ACCTEST program in various       
			   sequences to decide which        
			   PC Card is defective.            

If after following the suggested procedures to correct the problems and a
certain test item still fails, please contact your dealer or Accton
Technology Corporation.
