An 8 MB binary named only after the Lenovo V110-15AST, with no board number, revision or version in the name. The size fits a 64 Mbit SPI flash chip, the common BIOS chip size for this class of laptop. It is a raw image meant to be written with an external programmer when the existing firmware is corrupt and the machine powers on with no display. Since the motherboard is not identified, compare the board markings on your unit with known V110-15AST boards, and read and save the original chip before writing anything.
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 @bioshub. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
