Firmware package for an ASRock H270 motherboard, labelled with version 2.50, in a 12.1 MB RAR archive. The name does not specify the exact board model within the H270 range, so confirm it against the sticker or silkscreen before use. The archive may contain an official update file or a dump intended for SPI programming. When writing with an external programmer, back up the original chip first, since it holds board-specific data, and make sure the image size matches the flash chip capacity.
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.
