I'm a graduate student who wants to utilize Intel SGX instructions. I heard that the new CPUs, which include Intel SGX instructions, will be released by 26th Oct, 2015.  And I'd like to buy one of them.
Q1. Do I have to need a motherboard which contains a BIOS supporting configuration for SGX? (enable/disable SGX and/or adjusting Enclave memory size)
Q2. If I do so, which motherboards can I buy?
