Ok, it may be a good method to make a testing. I will try it.

If you can boot an EFI ACPI OS then you could run the ACPI tests. You can get a copy from: I'm not sure if this code has been ported to EFI?
Where can I get a UEFI OS image? Or, how to make an UEFI OS image from the UEFI OS live CD?It seems that the method is different from that to makinga legacy OS image from OS live CD.
