Acer 4630Z BIOS binary, 2.00 MB, fitting a 16 Mbit SPI flash device. No motherboard number, revision or firmware version is given, so match the board yourself from the silkscreen. This kind of dump is flashed directly onto the chip with an external programmer to repair boot failures caused by a corrupted BIOS. Make sure the chip capacity matches the file size. Back up the original contents, and verify the write by reading the chip back.
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 @ComputerBIOSBinFile. Enginerys does not host this file.
