Hello Adios, thank you very much for contacting us.
About your situation, please bear in mind that Intel® NUCs are designed to host Microsoft(R) Windows operating systems, please refer to the following link: http://www.intel.com/support/motherboards/desktop/sb/CS-034034.htm
Since FreeBSB-10.0 is working fine when using BIOS version 0032, I would recommend keeping this BIOS if you decide to continue using this operating system.
I can share this information with our developers as a heads up but please be aware that we cannot offer a solution for this problem.
