BIOS dump for the ASUS X553MA laptop, 8 MB raw binary with no board revision or version stated in the name. An image of this size is written to a 64 Mbit SPI flash with an external programmer, for example when the machine powers on with no picture or loops after a bad update. Confirm the chip marking and capacity first, then read and save the original contents, which also hold serial and system information. Check that the board revision matches the source unit when possible.
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 @biosbigarchives. Enginerys does not host this file.
