Uninformative firmware file named HxDs, 768 KB in size, with no extension and no brand, model or board number. The name may refer to a hex editor rather than a device. An odd capacity like 768 KB does not match a standard SPI chip, so it may be a partial region such as a BIOS area without the descriptor or ME, or a fragment. Open it in a hex editor to identify the contents before use. Do not flash it as a full chip image, and back up any chip before writing.
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 →
