Raw BIOS binary for a K43LY mainboard, revision 3.1, 4 MB in size, which corresponds to a 32 Mbit SPI flash chip. The name gives no other details such as EC version or regional data. Technicians use a dump like this to reprogram a corrupted BIOS chip with a programmer, either in-circuit with a test clip or after removing the chip. Before writing, confirm that the board revision on the PCB matches 3.1, read and save the existing contents, and confirm the chip on the board really is 4 MB.
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.

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 →
