Is it > impossible for a non-PCI system to have ACPI? When ACPI was concieved (~1999 according to the spec I have handy) ISA-only PCs were somewhat scarce. It's probably safe to say anything that supports ACPI has PCI (For x86[64] at least, I don't know about ia64) The spec mentions as a minimum requirement for OSPM/ACPI systems amongst other things.. "A _PRT method for all root PCI bridges" which pretty much sounds like it's at dependant on PCI (or a later evolved standard like PCIE) hardware being present. Dave -- http://www.codemonkey.org.uk
