Where I can find document for PCI Express IP in Qsys?

--- Quote Start ---

I want to use PCI Express IP in Qsys for my next project. When I click "document" (http://www.altera.com/products/ip/iup/pci-express/m-alt-pcie8.html) link from qsys, it is showing "the page is not longer available". Is there any method by which I can get this document?

NB: I am using Quartus II 11.0.

By the way, probably you could also highlight the document link bug in Qsys to Altera for fixes.
