As promised, quicker way to fix config page issue
1)Putty into S3
2)Paste the code in below.. Will replace Save&Apply with Save&Apply.
sed -i 's/Save\&Apply/Save\&Apply/g' /usr/lib/lua/luci/model/cbi/cgminer/cgminer.lua
Thanks for this. Just updated one of my Batch 1 S3s, applied the line above and everything works great!
One question, what values would/should/could be entered in that new 'Voltage' field for the S3? And what effect would these values have on the operation?
