ChainMiner for M Board Version 2.X boards
DO not use this guide for Version 1x m-boards.
It will fry your chips.  This is only meant for Version 2 of the M-board.
I apologize for grammar as I took 2 sleeping pills and I can barely feel my fingers.

1.login as pi or root

2.  type "nano /run/shm/.stat.log"   if you wish to see the performance of all the chips on your board before upgrading chain miner.
(optional step)
3.(backup your chainminer version)  (this creates a copy of the folder)
a. sudo cp -a /opt/bitfury /usr/bitfury.backup
b. cd /opt/bitfury/
c. pwd  (make sure you are in /opt/bitfury)
d. ls -al (or type dir)
e. rm -rf chainminer  (this removes everything in the chainminer folder and the chainminer folder itself)
4.  make sure you are in the /opt/bitfury directory and not in /opt/bitfury/chainminer (it should be deleted anyway
5.  type "git clone https://github.com/bfsb/chainminer.git"
6.  it should now start getting the chainminer git.
7.  now type "cd chainminer"  you should now be in the chainminer directory
8.  type "make"
9.  Its going to take 5-10 minutes to create the chainminer...maybe longer.
 I got some warning but everything was fine after it all finished.
 it will go back to a  bash prompt when done.
9a.  Just wait...this is the longest part of doing this change..
10.  sudo reboot
