Working BIOS image for an NEC laptop on board DAFF4AMB6B0 revision B, stated as an 8 MB dump and reported fully working in the name. The DA prefix followed by a code and MB marking follows the Quanta ODM numbering pattern, which NEC used for some notebooks. Flash it to an 8 MB SPI chip with an external programmer after saving the existing contents, since serials and configuration data live in the original. Check that the board number and revision printed on the PCB match before writing the image.
