BIOS dump for the Acer Predator Helios 300, built on Compal motherboard LA-E921P revision 1B, archived as RAR of about 5 MB. The name states Compal directly, which agrees with the LA-xxxxP numbering used by that ODM. Use it to recover a bricked board by writing the SPI flash with an external programmer. Save the original firmware before writing so serial and configuration data can be restored, and make sure the image matches the chip capacity and the revision printed on your board.
