Ans:- No, not currently. The Memtest software is made for the traditional PC-BIOS environment whereas the Minnowboard has the new UEFI firmware. So, until a new version of Memtest is released for the UEFI, it won't work.
2. Does the MinnowBoard support SATA port multiplier functions?
Ans:- Yes, the SATA controller on the Minnowboard does have the hardware support for a SATA port multiplier but there is no software support for it at this time.
