It's working on R4.
Well i'm willing to experiment,is that your problem?
Simple explanation on PS questions would help.
Thx
R4 is a completely different design with a different type of fan.
S5 controller/software doesnt support S7 boards, simple as that.
Firmware for the s9 is closed source, there is no way to enable an extra board.
BMMiner is open sourced. The only closed bit is the bitstream for the FPGA.
Compilation isn't too hard and the source isn't terrible to read. Just make sure you have the 32 bit compatibility stuff installed for your toolchain and zlib if I recall.
