BIOS image for the Lenovo ideapad 330S-15AST laptop, stored as a zipped bin file of 4.03 MB. The size suggests an image for a 4 MB SPI flash chip, although the name does not state the chip model. Use it to recover a board that stopped booting after a failed update or a corrupted chip, writing it with a programmer such as a CH341A and a clip. Save a full read of the original chip first, verify the write afterwards, and check that the extracted image size matches the chip 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 @vinafix_bios. Enginerys does not host this file.
