This chapter explains how to isolate and solve 3C590 PCI
adapter problems.
Make sure that the adapter is correctly installed. (See
Chapter 2 for installation instructions.)
Troubleshooting with the Diagnostic Tests
The three diagnostic tests on the 3C59X
EtherDisk
diskette
check the adapter’s overall operation and permit the isolation
of faults. You can run the diagnostic tests after installing one or
more 3C590 PCI adapters, or when a fault is suspected. If the
tests in their default configuration do not isolate the problem,
you can change the test parameters to meet specific
situations.
Always run the diagnostic tests with no device drivers or
memory managers installed. Whenever you plan to run the
diagnostic tests, you must first boot 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. (Refer
to the section “Accessing DOS” in Chapter 3.)
If you are running under DOS 6.x or higher, press [F5] when the
message informs you that MS-DOS
is starting. This prevents the
CONFIG.SYS and AUTOEXEC.BAT files from being loaded into
memory. After running the diagnostic tests, you should reboot
your computer to communicate on the network.
The diagnostic tests are divided into three groups, designated
Group 1, Group 2, and Group 3.
Group 1 tests check the physical components and circuitry
on the adapter.
