you can make the sd card at a windows system, but to change the ip settings you need to either use a monitor/KB with the bitfury, or use linux to change the network interfaces file.

The chainminer in the image works, but not optimally. once the sd is in the rpi with the right ip settings, do this:

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)
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

It is much better version, and will cut your error rates massively. I went from 10% errors to 3%, and still have some tuning to do that should bring it under 2%

What about Chainminer updates to M-board v1.0? Any words out on that?

Guys FWIW, I tried the new chainminer with v1.0 board. It did not improve my hashing peed and it did not fry my boards. For the record I have only 3 H boards. But somehow my hashrate was spread across all over the 16 boards in the webpage instead of the first 3 boards..
