  • Page 35: Before Running The Tests

    These tests are run as default tests. The Group 2 test (Network Loopback Test) is not used on twisted-pair adapters such as the Fast EtherLink 10/100BASE-T4 PCI adapter. The Group 3 test (the Echo Exchange Test) tests the adapter’s ability to transmit and receive data while on the network.

  • Page 36: Starting The Diagnostic Program

    Starting the Diagnostic Program Always run diagnostic tests with no device drivers or memory managers (EMM386.EXE and HIMEM.SYS) installed. Whenever you plan to run the diagnostic tests, you must first start your computer from a DOS diskette containing no device drivers, or you must exit to DOS if you have an operating system other than DOS.
