BIOS archive for the Gateway 4250s laptop, a brand owned by Acer, packed as a 1.92 MB RAR. The name gives no board number, chip type or version, so check the contents and compare them with your machine before use. Images like this are written to the SPI flash with an external programmer to revive a board that fails to start after a bad update. Read the original chip and save that copy first. Also make sure the image size matches the chip, since a mismatched file will not program correctly.
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.
