Original 2 MB read of the flash chip at position U22, identified as a 25Q16BV, a 16 Mbit SPI part matching the dump size. The file has no extension and names no laptop or board model, so its source must be confirmed some other way before use. The reference designator U22 helps locate the chip on the matching board. Write it with a programmer that supports the 25Q16 family, verify after writing, and keep a copy of the contents you replace.
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 @bios_laptop. 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 →
