ACPI is designed to bridge the gap between legacy machines and legacy-free machines, but it is not a thingy to enumerate ISA devices. Processors, APICs and the likes are all present in the ACPI namespace and definitely are not ISA devices. I like to think that ACPI allows enumeration of devices that are not attached to a bus and in that way serves as a bus itself. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
