HP laptop BIOS archive with a truncated DOS-style name, 16.6 MB, associated with Compal board LA-K209P. The short name gives no model or version, so verify the board number on the PCB before use. Compal uses the LA-xxxxP pattern for boards it builds for HP and other brands. Dumps like this are written to the SPI flash with a programmer such as a CH341A to revive a board with corrupted firmware; back up the existing chip first and make sure the image size matches the chip 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 @Laptopbiossolutions. Enginerys does not host this file.
