This chapter explains how to isolate and solve problems that may
occur when you install the 3C509B NIC in a PC running DOS,
Windows 3.1, or Windows for Workgroups.
Checklist
If you experience problems installing the NIC, first check
these items:
■ Check the NIC LED, as described in “Link LED ” in Chapter 1 .
■ Check the connectors. Examine the cable for obvious signs
of damage, wear, or crimping. Substitute a known
working cable.
■ Check whether the NIC software is correctly installed. See
Chapter 4 .
■ Make sure the drivers installed are correct for the network
operating system you are running (see
“Installing Other
Supported Network Drivers ” in Chapter 4 ).
If the problem persists, go to related procedures in this chapter or
refer to
Appendix D , “Technical Support .”
Diagnostic Testing Under Windows 3.x
The Configuration and Diagnostic Program, on EtherDisk diskette 2,
includes the diagnostic program used for DOS, Windows 3.x, and
Windows for Workgroups. Run the diagnostic tests after installing
the 3C509B NIC to check overall NIC operation and to isolate
failures. After the NIC is installed, if the default tests do not isolate
the problem, tailor the test parameters to accommodate your
specific situation.
Do not run diagnostic tests with device drivers or memory
managers installed.
Boot your PC to DOS to avoid installing device drivers or
memory managers.
