they are using the "lastest intel source code" in the 06-07-2006 beta. however, at this moment basic power saving functions are the focus of testing. they are working now on supporting dynamic irq allocation according to the readme.i am beta testing ecs 2.0 on an intel motherboard running a pentiumD processor with smp mode enabled. unfortunately the intel mobo's bios doesn't allow the user to manual configure the irq(s) and the current acpi can not reassign irq(s), yet. all my addin cards work; but, i cannot use usb because of irq conflict :-{
