Acer BIOS firmware archive whose name refers to the 5338 series and model MS2264, the internal model code Acer uses on its labels. The RAR measures about 1.09 MB and no board number, version or test status is stated. Acer laptops in the same series can ship with different mainboards, so compare the board number printed on the PCB with the source of the image before flashing. When reprogramming the SPI chip with a programmer, save a copy of the original contents and check that the image size matches the chip.
