ANUALLY
If a conflict exists, you may have to change the settings
of other NICs or adapters that are in your PC. The 22
RAM address ranges are as follows, with the default
in

:
Interrupt Request Level
A 3C319 NIC can operate on one of four interrupt levels
for IBM mode (2 [9], 3, 6, or 7), or one of eight interrupt
levels for 3Com mode (2 [9], 3, 5, 6, 7, 10, 11, or 15).
The default interrupt level is 2, but the 3C319 NIC can
operate on any of the levels if necessary. If a conflict
continues, you may have to change the setting of other
NICs or devices that are in your PC.
Other Configuration Options
The Configuration and Diagnostic Program also allows
the selection of the following additional parameters.
3Com recommends that you avoid changing these
configuration settings.
Memory Mode
—Allows operation with 8-bit or 16-bit
memory interfaces. The default is 16-bit, but the 8-bit
option is provided for backward compatibility with older
PCs. The Parallel Tasking feature is disabled in 8-bit mode.
I/O Mode
—Allows operation with 8-bit or 16-bit I/O
interfaces. The default is 16-bit, but the 8-bit option is
provided for backward compatibility with older PCs.
