There are four kinds of "PnP" at least. IEEE1394 (parallel PnP) and serial PnP are independant of ACPI. BIOS PnP serves the same purpose and is replaced by the ACPI ability to enumerate system devices. ISA PnP enumerates devices on legacy ISA busses. > Does PNP support hot-plug? There are definitely ACPI devices BIOS PnP supports some hotplug for laptop docking issues. It is a lot more primitive than the ACPI layer. In addition it is strictly forbidden on pain of nasty things occuring to use BIOS PnP and ACPI at the same time. Having both use the same kind of driver registration would be nice. ------------------------------------------------------- This SF.Net email is sponsored by: YOU BE THE JUDGE.
