Small 28 KB firmware archive called NPHY_TGP, where TGP very likely refers to Intel Tiger Lake PCH platforms. NPHY is probably a PHY firmware module used inside the Intel flash image, but the name gives no board or model, so treat it as a component file rather than a full BIOS. Technicians add such modules when rebuilding an ME or flash descriptor region with Intel FIT. Make sure the module version matches your platform, and always keep a full dump of the original SPI flash before you edit it.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
