The .hrom prefix provides an experimental mechanism for reducing option ROM space usage on systems where PMM allocation fails, by pretending that PMM allocation succeeded and gave us an address fixed at compilation time. This is unreliable, and potentially dangerous. In particular, when multiple gPXE ROMs are present in a system, each gPXE ROM will assume ownership of the same fixed address, resulting in undefined behaviour.
