I have X10DRi-T motherboard and 2 Intel Xeon CPUs installed on it, starting install Ubuntu 16.04. Everything looks fine, opening Ubuntu OS, etc. But, I found only one CPU was detected.
When I checked BIOS, the 2nd CPU was not recognized at all. Could you please advise me what I need to check?
I already swap the CPUs on the board--it tells the 2nd CPU itself is OK, running on the 1st slot.
