I am a little confused by your question. Virtex-II is an FPGA and the XC17V00/XC18V00's are configuration PROMs. Do you need some information/demos on one or the other (perhaps both). Please give us some more information and details.
Back in the day when Virtex-II was introduced, we only had prototyping boards with little or no peripherals. Today's development boards are loaded with a variety of interfaces and offer a wide variety of canned demos. While I doubt that there is anything specifically targeting the older AFX-200 series boards, you are free to browse the application notes specific to Virtex-II: http://www.xilinx.com/support/documentation/virtex-ii_application_notes.htm
