If there's no option to disable it, and it's an Award BIOS, you can use a program called modbin6 (get version 1.00.38) to add that menu option back into the bios. Microsoft requires motherboard manufacturers to hide this option in the bios config to prevent it from being disabled, otherwise they won't "windows" certify the board. If you disable ACPI, things will stop trying to share IRQ's. Jay
