So, Still trying to see what can be done to a 1680XA system to upgrade the motherboard, Now, keep in mind the mATX in it now is a single core @ 3ghz, so it actually runs XP well, and putting 3g of ram, and doing the Register mod, allows it support any card in it.
I have tried two boards now with the PCIe SVDO Adapter, the systems do output video, but don't detect the correct panel resolution, it sets it to the smaller 800x600 on the larger 1024x768 panel.. so it has bars/garbage on left and bottom of screen, there is a hint that the Intel BMP tool can be used to edit the video bios, however, that program is non-existent. --- I only tried to get video working first before moving to any software install, but since no video solution, not going to tear down frame to put board in.
Motherboards tried
Intel DG965RY ( wont fit, its too big, wasn't paying attention )
Intel DG43GT ( would fit, but does same issue ) .. I think this Motherboard may WILL work in a 16903A , i have one here i can try it in.. , but would require cutting out the back plate to support the MB I/O I have a parts machine with missing bezel.
So if anybody has an extra Bezel for a 16903A and 1680X and will to part with, LMK
