Re: [pci] Newcomer to PCI

It's keyed as a universal card, so it should work in any PCI slot at 32-
bit, 33MHz.  You just need user constraints to tell the Xilinx software 
whether it is 5V PCI I/O or 3.3V.  Note that there are now two 
(completely?) different versions of the development board out, so if 
someone on here gives you project files for the old one you'll probably 
have some editing to do.  Incidentally, the Virtex/SpartanII is the final 
Xilinx FPGA likely to support the 5V PCI systems...all the later chips 
including the SpartanIIE are requiring 3.3V I/O...which is only present 
nowadays in expensive server motherboards with 64-bit 66MHz slots.  
This Memec card *does* work in those server systems as well though.

And Wishbone info is in the blue bar at the top of (all of) the opencores 
web pages.  You'll want to make your design a wishbone target, to hook 
up to the wishbone master interface of the pci core.  (Unless, of course, 
you want to do bus mastering with the card, but that's beyond the 
scope of what I have time to help with right now)

You can email me, but I'd rather keep it on the forum if that's ok...your 
questions might help some other people, and others can help answer the 
questions as well.  I don't know *everything*...
