An alternative boot methodology that begins with legacy-free firmware allows
the
peaceful coexistence of legacy-free and legacy option ROMs in a system. Legacy-free
firmware provides a legacy-free boot path from system power up to operating system
loading. This legacy-free boot path is independent of any legacy firmware. A legacy-free
boot manager boots from an ordered list of OS loaders. If a legacy boot option
is available, legacy-free drivers that have already been loaded may be stopped,
and a legacy boot using legacy firmware may be initiated, without having to reboot
the system.
