A similar function is achieved by the "'''top hat flash'''" which comes at no extra cost with many Elitegroup mainboards like ECS KN3 SLI2 Extreme  with MCP55 southbridge. After bootup, it can manually be lifted off the original BIOS chip, so the original BIOS can be reflashed after a failure. /rst is wired to /oe on the spare chip otherwise 1:1. top hat flash is equipped with a Winbond W39V040AP  FWH. It may rely on particular circuitry on the mainboard to operate.
