Compressed BIOS firmware for the Acer Aspire 5542G in the 303G25Mi configuration, packed as a 709 KB RAR archive. The name does not state the mainboard number or revision, so compare the board inside the laptop with the source of the dump before trusting it. Acer machines of this series were built by ODMs, and different board versions can share a model name. Extract the archive, check the image size matches the flash chip, back up the original contents and then reprogram the chip with a hardware programmer.
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 @biosarchive. Enginerys does not host this file.
