You can see here all the pc specs
It looks like intel is the manufacturer of the mainboard
Anyway, Hystou doesn't respond to emails or on the online chat
That's how it looks:
Intel produced a sample board design called SkyBay. This was never an Intel product, however; other manufacturers used the design to product their own boards. Those manufacturers are responsible for the BIOS; there are no updates from Intel.
Bottom line, you need to contact Hystou to see if they have any BIOS updates.
