I asked the question on the DA forum I'm curious myself.
I moved my old PC to the to flash the RK2 it was easier to move than the controller. It was the one I was going to use to run myreef so it was in the fishroom anyway. I just couldn't get it to work so I had to go the Bluetooth route to a different PC.
But who knew you could run Windows XP on a 486 with 128m of ram.
