There are also things that the BIOS does that the operating system must talk to over time in order to coordinate things like power management and "simple" things like powering off the system (hint, that's not a simple thing). So your old BIOS was still sitting there running and providing services to the operating system just like UEFI does so today. That has not changed except that a number of the issues involved with that old interface have been fixed up, and a number of new interfaces have been added. greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
