BIOS firmware archive identified only by the motherboard number LA-5661, 645 KB in ZIP form. The LA- prefix is the Compal board numbering pattern, and Compal manufactures boards for several laptop brands, so the name alone does not reveal which notebook model it fits. Such files are used to rewrite a corrupted SPI or EC flash with a programmer. Check the LA number and any suffix on the PCB, open the archive to see which images it holds, back up the original chip and confirm the image size matches its capacity.
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.
