:-\Unless I am totally missing sumtin which may be possible, but from my experience this "Custom Antminer s7 Firmware" Doesn't Work At All.
It appears to just be a bloated non-functioning Antminer S7 batch 1 firmware copy.  It even has the "ping 114.114.114.114" line in /etc/init.d/cgminer.sh NOT commented out. Since currently (well at last time checked) this ip address is down and has been for a week or longer Cgminer will not run.  Also when I went to check the version of Cgminer after running on the SD Card that "new firmware" was dd'd to it was still showing 4.8.  I contacted Ziwalla (or how ever the spell it) Support and no response, not even an automated response.  So it's either one of a few things possible going on here:

1. Totally Doesn't Work At All
2. Does not Run on My Batch
3. Terrible Customer Service / Non-existence Support

 
Has anyone actually gotten this "Custom S7 Firmware" to Run ?

I am probably just going to Extract Original Batch 1 Firmware
to a virtual linux box and fix the cgminer.sh file
And then possible update/upgrade system
Install new version of cgminer and
Then recompress to flashable tar or just make a img file to
write to Sd Card boot.  
These were really the only features i was interested in if anyone has already done this and would like to share
That would be helpful otherwise if anyone else wants when i'm done i can post it up here or new thread for people
to freely download and use...
