A similar function is achieved by the "'''top hat flash'''" which comes at no extra cost with many Elitegroup, and some Gigabyte and Albatron mainboards like ECS KN3 SLI2 Extreme with MCP55 southbridge (which is getting severely out of stock around central europe as of 8/2007 unfortunately). 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.
