BIOS for the ASRock J1900-ITX mini-ITX motherboard, sized for an 8MB flash chip, compressed as RAR. No firmware version is mentioned, so check the contents before use. A dump of this kind serves to recover a board that fails to boot after a corrupted update, written to the SPI chip with an external programmer. Verify the chip on your board is 8MB, read and keep the original contents first, and confirm the board model printed on the PCB.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
