BIOS image for the Acer Aspire M5-581 and M5-581G, Wistron board 14205-1, for the configuration with GeForce 730M discrete graphics and a Core i3-3337U processor. Wistron uses five-digit numbers with a dash revision like 14205-1, and this same board number appears across several Acer models. Make sure the GPU and CPU variant on your board matches before flashing. Extract the RAR archive, check the image size against the SPI chip, and back up the original before writing with a programmer.
