This is an apples and oranges comparison, and there is no reason for us to expect it to work any differently. The 'real' slot on the motherboard is PCI Express; the riser cards have bridge chips on them. Dell obviously chose to implement the PCI-X riser in a different way than the PCI-E riser, and the result is different behavior. This goes back to my original point: the IRQ assignment behavior has nothing to do with the manufacturer/type/style of the card, and everything to do with the implementation of PCI, IRQs, BIOS and other bits by the system manufacturer. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
