Abstract
Methods and systems are described for managing manufacturing modes in a unified extensible firmware interface (UEFI) basic input output system (BIOS). The UEFI BIOS can include a PEI (pre-EFI) manufacturing mode driver, a PEI interface, PEI drivers, a DXE (driver execution environment) manufacturing mode driver, a DXE interface, DXE drivers, a SMM (system management mode) manufacturing mode driver, a SMM interface, and SMM drivers. Manufacturing mode data is stored and accessed through a PEI manufacturing mode driver, a DXE manufacturing mode driver, or a SMM manufacturing mode driver, and/or any combination thereof. The PEI interface is used to communicate manufacturing mode data between PEI drivers and the PEI manufacturing mode driver. The DXE interface is used to communicate manufacturing mode data between DXE drivers and the DXE manufacturing mode driver. And the SMM interface is used to communicate manufacturing mode data between SMM drivers and the SMM manufacturing mode driver.
