That is one exotic mobo, from quite a few years back. If I remember correctly only EPOX, SOYO, and Foxconn made motherboards with visual LED displays like this.
I went to the Foxconn site once more and lo and behold, the manual is right up for download again. (although the site only supports downloading from IE.)
the boot codes beginning with F are nVidia added, I see. It is likely to be an error with the chipset-if F0, F1, F2, and F3 are all related to hardware identification and COM ports, it would logically follow that it is a hardware error-the nVidia chipset includes everything on the board except the Realtek audio deck and in some boards a realtek NIC, so I'm afraid you might have to replace the board.
