Compressed BIOS package for the Acer Extensa 4230 laptop, a 822 KB zip archive. The name gives no board number, revision or firmware version, so open the archive and inspect its contents before use; it may hold a raw chip dump or a vendor update file. Raw images are written to the SPI flash with an external programmer, while update executables run from the operating system or DOS. Check the motherboard number on the PCB against the image, and make a full backup of the existing chip before writing anything.
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.
