The 6 PIN jumper - Pin J_PW_NVRAM  - on every motherboard that I am aware of are not Power, They are jumpers to clear NVRAM (reset bios) and jumpers to clear Bios password.
Power Cable ships with ioDriver2 Duo has 2 6pin connector. Big one for power supplier and small one for io Memory Card. I find nowhere to plug the Big one connector on my R920 motherboard.  A 6 Pin J_PW_NVRAM connector reside on the motherboard.  So my question is can I use it for my io Memory Card if I can find a 6pin-to-6pin power cable.    By the way  there are many pins covered by black paper on the back of my power distribution board(I think it's PDB ,in front of my PSU.). Are they also additional power supplier connector?
