Tri-Head PCI card with Altera gpu(?)

Silkscreen is the labeling printed on the circuit board. Assuming you can get the design files then you would just download them using the programmer built into Quartus II or MaxPlus II which would also require a special programming cable like a USB-Blaster or byte-blaster.

If this board only has an FPGA, PCI interfaces, SDRAM, and audio connectors then I don't think you purchased what you thought you were getting. It sounds like a development kit to me which is used by engineers to prototype their own work. This prototyping requires hardware design knowledge and can take weeks/months/years to design hardware for these devices (talking about the FPGA not the board). So if your friend sold you this board without telling you that then I would have a little word with him if you know what I mean :D.
