I have bought a DS-47 with 16 GB of RAM and a Intel 335 SSD.
The current BIOS does not detect the SSD-drive at all. Even changed from ACHI to IDE with no luck.
Tried the 335-drive on another computer and it worked there (upgraded firmware at the same time).
The DS47 BIOS installed (DS47D000.100). I’ve requested Shuttle for support, and they probably needs to update the BIOS.
