Raw 2 MB binary firmware image named for an L-500 model with the board reference LA-4982 in braces. LA-numbers follow the Compal board scheme, so check the LA-4982 code on the PCB before use; the name gives no brand, revision or version. A 2 MB file matches a 16 Mbit SPI flash, which must be the size of the chip on the board for the image to fit. Write it with a hardware programmer such as CH341A or RT809, and always save a read of the original chip so the board can be restored if needed.
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.
How to open a .bin 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 →
