Making a fat 16 bootble micro SD card is quite easy in linux , for windows use something like this

Great, I'll give it a shot at the office tomorrow. I did the sd but followed KnC's directions. It didn't say make it bootable or FAT16, so I did one non-bootable on FAT32. Otherwise it looked like it copied because it came up saying RC6 as the firmware before I updated it. I guess 5 of my TH will be down until I can get a couple more BBBs here.
I don't really mind the Neptunes. They seem just a bit more finicky than the Jups & Sats I had. Plus KnC refunded my $10,166 and I'm getting these cubes second hand. Seems like a win-win for me.
