DOS Diagnostic Tests

You can run the Conﬁguration and Diagnostic Program to perform DOS diagnostic tests after installing the 3C395 NIC or if you suspect a hardware failure.

Table 4-2 summarizes the DOS diagnostic tests.

Table 4-2 DOS Diagnostic Tests

Test Description

Group 1 These tests check the following items:

■ Register Access

■ EEPROM

■ FIFO Loopback

■ Ethernet Core Loopback

■ Encoder/Decoder Loopback

■ Interrupt

Group 2 This test does not apply to the 3C395 NIC. Group 3 The Echo Exchange Test tests the NIC’s ability to

transmit and receive data while on the network. To run this test, you need another PC to set up as an echo server that receives packets from the NIC being tested and echoes them back to the NIC.

If the NIC passes the Group 1 and Group 3 tests, hardwar e failure is ruled out. If a problem remains, look at cabling, software, and other issues that affect network functionality.

About the Conﬁguration and Diagnostic Program

The Conﬁguration and Diagnostic Program is a DOS application that must be run with no drivers or memory managers installed. You need to boot from DOS without running the AUTOEXEC.BAT or CONFIG.SYS ﬁles. The program does not run in Windows NT DOS windows.

Windows NT users need to boot the computer from a bootable DOS diskette before starting the Conﬁguration and Diagnostic Program.

Table 4-4 Troubleshooting Tips (continued)

Symptom Tip

The NIC fails diagnostic tests.

■ If the NIC fails the Group 3 diagnostic test, be sure that

the test is set up correctly, that the NIC is connected to an inactive, properly cabled network, and that an echo server is set up on the network.

■ Replace the failed NIC with a working NIC.

Run the diagnostic tests again, using the same option settings as those used on the failed NIC. If the working NIC passes all tests, the original NIC is probably defective. For information on product repair, see Appendix

■ Install the NIC in another functioning PC.

Run the tests again. The first PC you used for testing may be defective if the NIC passes the tests in this PC.

■ Remove all other NICs from the PC and run the tests

again. If the tests pass, the other NICs may be causing

contention. Check the configuration settings. Change the settings if they conflict with another device. See
