Combined BIOS and EC firmware for the Acer Nitro AN515-54 gaming laptop, platform code EH50F, at version 1.09, in a 5.85 MB RAR archive. Having both images is useful because a corrupt embedded controller code can leave a board with no power-on, no charging or fan problems even when the main BIOS is intact. Technicians write these to the respective SPI chips with a programmer such as a CH341A or RT809H. Back up both original chips first and verify each image size matches the chip it is intended for before flashing.
