The problem is that modern laptops do not have a serial port and you have to shop a USB to serial adapter and a nulmodem cable. I really hope that the normal online update will be made possible soon.
Updated to 6.6. Unfortunately swap manager still does not work. It does not find my usb stick, CF card or HDD and thus cannot create a swapfile.
I have DM8000 and the latest OpenPLi 3.0
