Well with 4 PCI interrupts, it doesn't take that many PCI devices before you must be sharing. Of course it seems some higher end systems split up the PCI bus in some way and run different IRQs from the APIC to different slots. I suspect that is how I see IRQ's of 177, 185, 193, 201, 209, etc on some systems. If you have a server with an IO APIC then I suppose you have a rather good chance of avoiding shared IRQs for the most part. -- Len Sorensen ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
