Troubleshooting Windows 95 (NDIS 3)
Windows 95 sometimes has trouble selecting available
resources for the 3C389 PC Card, causing the 3C389
PC Card not to function. If you find that your
3C389 PC Card is not functioning, follow this procedure.
1 Click Start.
2 Go to the Settings menu selection and click Control
Panel.
3 Click System.
4 Click the Device Manager tab.
5 Check the 3C389 PC Card network adapters icon for
for indications of a resource conflict.
The resource conflict indicator is an exclamation point
inside a yellow or red circle that appears on top of the
network adapter icon.
6 If you see a conflict indicator, double click the 3C389
PC Card networks adapters icon.
The properties dialog for the 3C389 PC Card appears.
7 Click the Resources tab of the dialog box.
There are three resources that must be correct before the
3Com TokenLink Velocity PC Card will function correctly:
the Interrupt Request (IRQ), Memory Range, and
Input/Output (I/O) range. The interrupt request value
should be a value between 3 and 15 that does not
conflict with any other devices. The memory range is
often set incorrectly by Windows 95. It is recommended
that the memory range be set in the 000D0000 to
000DC000 in a non-conflicting memory region. The
memory range 000C0000 to 000CFFFF is often used for
video caches and Windows 95 does not always exclude
memory regions that are already in use. Acceptable values
for the input/output range include any four consecutive
values beginning at 0300.
8 If EMM386.EXE is in your CONFIG.SYS, comment
it out.
