Interrupt Request Level

A 3C619C adapter 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 preferred interrupt level is 2, but the adapter can operate on any of the levels if necessary. If a conflict continues, you may have to change the setting of other adapters or options that are in your PC.
