BIOS or firmware image labelled s270E, supplied without an extension and measuring 8.00 MB. The name gives no brand, board number or revision, so the exact laptop it belongs to cannot be confirmed from the label alone. An 8 MB size usually corresponds to a 64 Mbit SPI flash chip, which is common on notebook mainboards. Before writing it with a programmer such as a CH341A, read and save the original chip contents, confirm the chip capacity matches, and compare the board markings with whatever the source of this dump was.
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 @biosfilebins. 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 →
