Here is the link to where I present my modded 340C:
For all D-Box enthusiasts !
I also described how I exchanged the harddrive (twice). You need to use a tool that also copies the boot sector.
As for the motherboard, exchanging the defect/domed capacitprs helped with all 340C controllers that showed symptoms like crashing (blue screens), not booting anymore, etc. that I laid my hands on. If you want to replace the motherboard(s), the LN10000EG is an option. Like the ML-series, it is EOL, but you might find it somewhere and I can confirm that it works - and in the message above, I describe what needs to be changed (e.g. on the old board +5V are taken from a WOL-socket and since the LN10000EG doesn't have that socket, I took the +5V from an internal USB port). You still might have to exchange a few capacitors on the small daughter board for the power supply, as it is needed with most Mini-ITX motherboards ( there are a few out there, that you can connect directly to an external 12V power supply, but then you would have to re-think all the 340C-internal wiring...). Continuing to use the power supply daughter board and the existing wiring also makes sure you don't need to re-think how to supply the voltage needed for the controller board.
If you make a fresh install, you also need to make sure you have the drivers for the CrystalFonts display of the controller. I never did such a fresh install, but in my 340C, I found a registry key labeled "embedded mode". I suppose this one is needed to make sure that the controller software always claims the top position of all windows. The CrystalFonts display and the front panel buttons use the PS/2 keyboard port and this can only work if the D-Box controller application is active/the top window.
Hope this helps!
