The bootloaders use physical mode, and there shouldn't be a separate physical vs virtual mode. It should be the same code with or without relocations applied. At worst we can set virtual address to the physical address, on buggy boards. Honestly if the problem is the EFI code is so buggy we can't use it in physical mode the answer is almost certainly not to use the buggy EFI code. The only bits that I don't think have an alternative are the firmware variable accesses. Which are a nice to have, but not a show stopper anywhere. Eric
