Abstract:
1. A resource compatible system for extensible firmware interface and basic input/output system, adapted to a computer system incorporating said extensible firmware interface and said basic input/output system at the same time; said computer system executes said extensible firmware interface system first after being powered on, and then when transferring to said basic input/output system, said resource compatible system executes the following steps: starting a mapping random access memory by a legacy OS support driver of said extensible firmware interface; finding out a legacy BIOS stored in a read-only memory by said legacy OS support driver; reading out a compressed ROM file stored in said legacy BIOS by said legacy OS support driver; decompressing said compressed ROM file by said legacy OS support driver and storing it in said mapping random access memory; setting up a warm reset vector in said mapping random access memory by said legacy OS support driver; and executing an action of warm reset by said legacy OS support driver to enable said computer system proceeding the warm reset procedure.
