DuetPkg BootSector:
Update start.asm(S)/start16.asm(S)/start32.asm(S)/efi32.asm(S) under DuetPkg\BootSector to follow the IA32 recommendations on switching to protected mode: Immediately following the MOV CR0 instruction, execute a far JMP or far CALL instruction. (This operation is typically a far jump or call to the next instruction in the instruction stream.)
