Having had a quick browse through the PDF spec at [link] - it states that it has "33MHz 32-bit PCI 2.2 host with support for 4 external masters". Now I'm the first to admit that my hardware knowledge is flaky, but that certainly sounds like support for a PCI bus of some description. Apparently there's no IDE support, only SATA (2 on the 'development platform' and only 1 on the 'reference platform'.
The Filebase could fairly easily be updated to cache downloads, only providing access to them if the original link goes dead. It already (optionally, since some people may not want it!) emails authors if their entries contain dead links. I'll look into modifying the code to retrieve the download links and store them for future use (with over 1000 entries on the Filebase, I'm not sure how much space they'll all take up).
