Many modern revisions of the WPCE773L series contain internal flash memory or pull their configuration directly from a shared SPI BIOS chip. If you replace a burnt WPCE773LA0DG with a brand-new chip, the motherboard may require an explicit EC firmware flash using a specialized programmer (such as the RT809F, RT809H, or SVOD programmer) via the keyboard matrix connector before the board will initialize properly.
