Archived BIOS firmware for the ASUS X453MA laptop, 3.13 MB as RAR, with the name marked ok to indicate a working image. No board revision or BIOS version is given, so the X453MA model is the only identifier. ASUS boards of this kind normally use an SPI flash chip, and the dump inside should be extracted and its size compared with the chip before programming. Technicians use such an image to revive a dead or looping board via a programmer. Keep a copy of the original chip contents, since it holds board-specific data.
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.
