Raw 4.00 MB binary labelled g470, which fits the Lenovo G470 notebook, although the name states nothing about board number, revision or BIOS version. A 4 MB image corresponds to a 32 Mbit SPI flash chip, so it can be written directly with a programmer such as a CH341A, RT809H or TL866. Before flashing, read the original chip twice and keep that copy, confirm the chip capacity matches, and check that the motherboard revision matches the donor board, because G470 units were made on more than one board design.
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 @biosarchive. 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 →
