Firmware archive for the Gateway NV52 notebook, an Acer-owned brand, packed as a 1.16 MB RAR file. The name does not say whether it is a raw dump or vendor update or which board revision it fits, so inspect the contents after extracting. For chip-level recovery, read and keep the existing SPI flash data before programming, and make sure the file size equals the chip capacity; note the NV52L variant has its own separate package.
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.
