Huawei BIOS package for a model coded RLEF-X on Quanta board DA0H9RMBAE0. The name states that the ME region and DMI data have been cleared, so the image is generic and can be used to recover a board without carrying another unit's serial information. The 9.54 MB zip is written to the SPI flash using a programmer. Before writing, save the original chip so you can restore your own DMI and serial values afterwards, and check that the image size matches the installed flash chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @efibios. Enginerys does not host this file.
