Hi all, I don't know if this is gonna help!
I just MSN with MSI RD couple hours to discuss the subzero problem on winchester and MSI 7025(NEO2), he fire a " possible fix bios" would like to let everyone try, unfortunately, I don't have any neo2 handy so I could not test it all.

Here is the newest BIOS only if you got the subzero problem!
Also hope someone can host that also!

Neo2 1.5x bios test only
