Xeon Phi 7210 Not Working in Ubuntu 14.04

I have Xeon Phi 7210 processor in the node that I am using. I am running Ubuntu 14.04 and followed the guide:

But even after following the steps, miccheck doesn't detect the Phi.

MicCheck 3.4.10-1

Executing default tests for host
  Test 0: Check number of devices the OS sees in the system ... fail
    no Intel(R) Xeon Phi(TM) coprocessors devices detected

Status: FAIL
Failure: no Intel(R) Xeon Phi(TM) coprocessors devices detected

Here is the output of dmidecode:

SMBIOS 3.0 present.
# SMBIOS implementations newer than version 2.8 are not

that guide is for the first Xeon Phi generation, code named Knight's Corner (KNC); yours is the second gen, Knight's Landing (KNL) which does not need any special drivers - it is just a many-core CPU.  No special software needs to be installed.

Yeah, I figured that out by my own accidentally though. Thanks for your response anyways.
