RAR archive holding a BIOS image for an ITX-M51-D926L board, version 1.2 D, with the name pointing to an 8 MB flash chip. No brand or chipset is given, so the board ID printed on the PCB is the main thing to compare against. The 2.82 MB archive should unpack to an image matching the 64 Mbit SPI chip. Read and keep the current chip contents before writing, and check that the extracted file size matches the chip, because a mismatched image will not fit or boot.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
