+ references must be setup for 32-bit protected mode.
+ @param EntryPoint The 64-bit virtual address of the function to call with
+ the new stack after paging is disabled.
+ @param Context1 The 64-bit virtual address of the context to pass into
+ the EntryPoint function as the first parameter after
+ paging is disabled.
+ @param Context2 The 64-bit virtual address of the context to pass into
