   REALTEK RTL8139 Fast Ethernet adapter.

   TROUBLESHOOTING
   --------------- 
   * Please follow below to run the Diagnostic program.
     1. Make sure that the adapter is completely plugged in its slot.

     2. Remove any add-on adapters from slot, except for VGA adapter.

     3. Disable PnP OS support in BIOS.

     4. Boot from DOS-only environment.

     5. When the Diagnostic program is started, there are no any TSR 
        programs running.

     6. If the adapter tests fail, try to use another slot.


   * EEPROM Test:
     This test reads and verifies the content of the Serial ROM.  The test
     fails if the Adapter configuration data kept in the Serial ROM returns 
     with a bad checksum, meaning the Adapter may not be programmed properly, 
     or the Serial ROM may be damaged.

   * Diagnostics On Board Test:
     In this test, traffic is generated at the rate of 100Mbps or 10Mbps,
     packets are being interrupted and reflected at the MAC level without
     reaching the network cable.  A fail test result represents a faulty
     Ethernet controller.
