Can't find schematics, sample codes, etc. about PCI Development Board, Cyclone II Edition

The physical picture of this development board is as follows:

However, I searched for a long time and only found some reference manuals, user manuals, etc. about it, but did not find the key schematics, demo programs, etc.

If anyone has the factory-installed DVD disc image, could you please share it with me?

Later, I downloaded a schematic from some paid forum. Although the title of the drawing was the same as that of the board, the position numbers of many components did not match.

For example, the U19 in this drawing is the Ethernet chip, but the actual device and the reference manual both say the Ethernet chip is U3. So I think this drawing is wrong.

Although I found information about it in the web time machine, there is only a brief introduction and no available data for download.
