Original 2 MB dump taken from the chip at reference U20, saved without a file extension. The label names no device, brand or board number, only the component position, which helps locate the flash on a matching board. The size points to a 16 Mbit SPI chip. Check the board number and revision printed on the PCB against the source before reusing this read. Then back up the current chip and flash it with a programmer, verifying the result.
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 →
