Unless something weird happens, you will use PCI interrupts and interrupt sharing. An easy check is good old 'vmstat -i'. > vmstat -i interrupt total rate stray irq3 1 0 mux irq11 443739 4 <-- ata0 irq14 57948 0 mwave0 irq10 3 0 fdc0 irq6 2 0 atkbd0 irq1 27962 0 psm0 irq12 861756 7 pcm0 irq5 174251 1 clk irq0 10915805 99 rtc irq8 13972991 128 Total 26454458 242 Note that there are no entries for my wi0 device but the magical 'mux' device has appeared. That is the IRQ assigned to pcic0 and it is shared with the devices plugged into that controller. You need to explicitly use sysctl adjustments to over-ride this and force you back to ISA interrupts. It is possible that, for some controllers, ISA may be used by default, but I don't think so. R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
