Hi ed,

>Yes, and Windows can also reassign the IRQs at will during configuration. It's not uncommon for the AGP slot to grab a fixed IRQ shared with one of the PCI slots.

This probably was my problem.

>It'd be very unusual for two PCI slots to steer to the same IRQ unless you have a lot of PCI slots.

It only has three PCI slots so this would not be the case.
Thanks for the clarification.

Walter,
