This README contains extended details about FPGA mining with cgminer
ModMinerQuad (MMQ)
------------------
The mining bitstream does not survive a power cycle, so cgminer will upload
it, if it needs to, before it starts mining (approx 7min 40sec)
The red LED also flashes while it is uploading the bitstream

For ModMinerQuad (MMQ) and BitForce (BFL)
-----------------------------------------
When mining on windows, the driver being used will determine if mining will work.

to scan, you must also use "-S auto". If you want to prevent cgminer from

The official supplied binaries are compiled with support for all FPGAs.
To force the code to only attempt detection with a specific driver,
prepend the argument with the driver name followed by a colon.
For example, "icarus:/dev/ttyUSB0" or "bitforce:\\.\COM5"
or using the short name: "ica:/dev/ttyUSB0" or "bfl:\\.\COM5"
For example, "icarus:/dev/ttyUSB0" or using the short name: "ica:/dev/ttyUSB0"
This option not longer matters since Icarus is the only serial-USB
device that uses it
