Drop in replacement for /usr/bin/cgminer

How to use:

1. (this step is optional but recommended) update your AntMiner S1 firmware to the latest one: https://bitmaintech.com/support.htm?pid=00720140411033846942qQqjOD460695

2. after firmware update is successful, connect via ssh to your miner (use putty under Windows)

3. enter this command to stop cgminer:

/etc/rc.d/S99cgminer stop

4. backup existing cgminer binary

mv /usr/bin/cgminer /usr/bin/cgminer-original

5. upload patched cgminer binary from your computer

scp [path where you download and extracted patched cgminer]/cgminer root@[IP of your miner]:/usr/bin/cgminer

(or use WinSCP under Windows)

6. make the new uploaded cgminer binary executable:

chmod +x /usr/bin/cgminer

7. start cgminer

/etc/rc.d/S99cgminer start

8. go to the AntMiner's web interface and append #xnsub at nicehash or westhash pool URL, press "Save & Apply"

stratum.nicehash.com:3334#xnsub

9. wait a minute and then go to the nicehash or westhash miner's details web page and make sure you have a green checkmark in "Extranonce subscription" column
