The UEFI legacy boot loader provides functionality for loading operating systems that are non-UEFI compliant in a performant manner. In particular, the UEFI legacy boot loader provided in one embodiment disclosed herein is configured to utilize UEFI disk services to load an O/S kernel and other O/S components. Once the UEFI legacy boot loader has completed loading the O/S components, the UEFI legacy boot loader enables interrupt handling by the O/S, relocates O/S real mode kernel setup code to a low memory region (below 1 MB), and switches a processor to a real mode of operation. The UEFI legacy boot loader then causes the real mode kernel setup code to be executed on the processor, to thereby complete the loading of the operating system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"UEFI boot loader for loading non-UEFI compliant operating systems","description":"A UEFI compliant firmware is disclosed that includes a UEFI legacy boot loader.
