Tested BIOS image for the Acer Aspire E5-473G notebook, board A4WAB with Compal number LA-C341P revision 1.0, packed in a 3.88 MB rar archive. The LA prefix identifies a Compal-designed motherboard. A dump like this is used to recover boards with corrupted firmware, no display or power-on loops by programming the SPI chip directly with a tool such as a CH341A. Read and keep the original chip contents before writing, and confirm the board revision and chip capacity match.
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.
