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.
