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
Table 4-2 DOS Diagnostic Tests
Test
Group 1
Group 2
Group 3
If the NIC passes the Group 1 and Group 3 tests, hardware
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.

This test does not apply to the 3C395 NIC.
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.
