BIOS dump labelled GU5FA, stated as 16MB, with no brand, board number or version given in the name. The binary is exactly 16 MB, so it suits a 128 Mbit SPI flash chip, typically an SOP8 part on the mainboard. Technicians use such images to recover a board after corrupted firmware, using an external programmer and clip or desoldering the chip. Make sure the model code on your board really matches GU5FA. Keep a copy of the original chip before overwriting it, as it may contain unit-specific data.
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 @ShareMan_Electronic_Files. 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 →
