Hi chinneric,
the RFX-board is just for the ULTRA-series as the mainboards of the ULTRA-series have a PCI-Slot (of course not compatible with PCI-cards for a PC or MAC) where the RFX-32 is plugged in.
A FX-board with 2 18-bit FX processors has been available as an option for the e6400 (classic).
So if your e6400 says that no FX-Board is installed then it is just this way.
You won't be in the position to obtain this FX-Boards from anywhere because it isn't available any more.
No reason to be sad as this FX weren't very sophisticated.
