First of all, Thanks to Sailorsat for her work.
Then I plan to buy a mini-ITX motherboard with a GMA3150 built-in.
I would like to put this MB in my CAB, with a J-PAC and an XP with Soft-15hz.
I think I understood that GMA processors are not fully supported and that only 5 resolutions can be used.

Does any gma processor are supported?Which are the 5 resolution that can be used?

many thanks for your futures answers!
