BIOS archive for an Acer Aspire 5336, according to the name, with no board number or revision given. Since Acer models of this kind were made by different ODMs, identify the mainboard code on the PCB before using the file. The 6.42 MB RAR may contain more than one image or tool, so inspect its contents first. It is used to reflash the SPI chip with a programmer when the laptop fails to post. Back up the original chip and make sure the image size matches the flash device.
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.
