That only informs the driver of what IRQ the card is using. (and I
thought the driver could find that by interrogating the card nowadays,
so maybe if you HAVE an irq= thing there, that is wrong?).

If you want to change the irq that the card uses, you have to set it on
the card.

Depending on the card, that may involve using the dos setup disk for
it, or if you are lucky and it is pnp (which probably is faulty on the
card ..), using isapnp, or if you are very very lucky, use 3c5x9setup.
