BIOS dump identified only as E89382 MB-4, with a 16MB size and marked as working. The name does not state the laptop brand or model. The 16.0 MB file has no extension, so it is most likely a raw full image for a 128 Mbit SPI flash chip. Compare E89382 with the markings on the motherboard before using it, since the identity rests on that code alone. Read and save the original chip with your programmer first, and only write the image to a flash part of the same capacity.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
