I'm mining Bern now on zpool : http://www.zpool.ca/?address=BFNkgNvmViXkjvAi9bbFXEvNkCFFKSar5V
My cpu/gpu are obsolete, so i just rented a rig at miningrigrentals , the algo (x14) is also a trouble factor, so i use
the autoexchange on zpool, to payout in BERN. With current price i breakeven with my 380 mined Berns
If you google 'ubuntu cpuminer', there are several guides and howtos to install it. The command line in the .bat to start up the miner
i can help a bit, but a serious cpu/gpu will be needed to make some BERN.
