Another thhing: could it be that some PCI adapter cards have to share IRQs? IRQ sharing is well-defined for PCI and they should be able to do so, but we always try to avoid it for performance reasons because if there's one unique IRQ for each device, no one has to decide and look which one it probably was. Unfortunately, even the Asus P2B-S motherboards at work are a little difficult to configure properly because AGP and the first PCI slot always share one interrupt (the only way to avoid that is to leave it empty) and I remember one other thing with the on-board Adaptec chipset (7890, I think). All of those Ethernet adapters I told you from in other mails have single IRQs :-) (Even the three ones in my desktop machine at work, and the other three ones in a little server machine - of course, the seven de interfaces in one machine (a single port card, a twin port card, a quad port card) don't have, but this machine doesn only some Ethernet routing to an uplink that's currently limited to 2 mbit/sec, so I don't care about performance that much.
