@ -26,6 +26,8 @@ There are two hidden options in cgminer when Icarus support is compiled in:
e.g. 2 means each FPGA does half the nonce range - default 2
fpga_count The actual number of FPGA working - this would normally be the same
as work_division - range is from 1 up to 'work_division'
It defaults to the value of work_division - or 2 if you don't specify
work_division
If you define fewer comma seperated values than Icarus devices, the last values will be used
for all extra devices
