List-Unsubscribe: , List-Archive: Your board has APIC enabled. This is an Advanced programmable interrupt controller. They are used on modern boards for smp (multi-processer systems) and for better PCI resource allocation. Your linux kernel has APIC support enabled; see the boot up messages. Windows won't put a soundcard on a high-order irq above 15 becasue dos boxes can't use the card; dos can't hook the hardware irq line from the APIC controller since t he dosbox runs in vm86 mode. Windows XP supports apic and high-order irqs; not sure about windows 98 and below. NT4 doesn't. Either try Windows XP or ME or disable APIC i n bios. Regards, Kerry.
