Raw 4 MB BIOS image for an ASUS K43LY family board, revision 3.1 as written in the file name. A 4.00 MB binary matches a 32 Mbit SPI flash chip, so it can be written directly with a hardware programmer after verifying the chip capacity. Use it when a board shows no display, loops on power or fails after a bad update. Read and save the original chip contents before erasing, and make sure the Rev 3.1 marking on the PCB matches, since dumps from other revisions may not boot correctly.
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 →
