BIOS image for a Wistron-designed board numbered 18791-1, with the Management Engine region cleaned, supplied as a 16 MB binary. The five-digit-dash-digit format is typical of Wistron boards fitted to Dell and other brands. A clean ME region is often used to recover boards that power on without display or fail after a chipset or flash replacement. Program it to a 16 MB SPI chip with a hardware programmer, after first reading and saving the existing contents and confirming the board number printed on the PCB.
