Nice find on the LCD BIOS settings!! I looked all over, but apparently, not everywhere.
They are of little use to me now, but I may post this on the MP3 car forums for others.
My next system will be something more capable, such as a Kontron mini-ITX system, with integrated on-board LVDS transmitter. They publish compatible display list with complete settings.
I should have done more research before buying the EPIA-EN 15000G and the LVDS-07G. Oh well, that's part of the learning process I suppose.
