Shuttle firmware read from a Winbond W25Q64BV SPI flash, a 64 Mbit or 8 MB chip, saved on 2025-05-08 as the timestamp in the name suggests. The RAR archive is 3.2 MB. The name does not say which Shuttle model or board it belongs to, so confirm the machine before using it. A dump like this is written back with a programmer such as a CH341A or RT809H to restore a desktop that fails to boot. Back up the current chip contents first and make sure the image is exactly 8 MB.
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 →
