Nope, Linux doesn't magically replace all the firmwares. You typical PC has a multitude of processors, and you only (mostly) control what runs on one class, the general-purpose CPU. You don't control what runs on the NIC, storage controllers (e.g. RAID), storage devices (disk drives, DVD drives, etc.), video cards, etc. Linux still has to deal with SMM and ACPI that is not Open Source. -- Chris Adams <[email protected]> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
