I just want to make sure we're all on the same page, because Miles' e-mail sounds like he _might_ be confused. cPCI !=3D Compaq PCI cPCI =3D=3D Compact PCI, which is a hot-swappable bus archetecture (and cab= inet design, and card form factors, and...) cPCI has no controller. It's not a controller spec. It's a bus and physical spec. Tho the Compaq PCI controller may give you many of the same benefits as a real cPCI system. cPCI is really just PCI, at 33/66MHz and 32/64 bits wide. It supports insertion notification, and removal request (open the latches, allow the software to shutdown and turn off the LED, then remove the board). Taking the 2 second look at the web page, it looks like they're working on both infrastructure for PCI Hot Plug, as well as a driver for the Compaq controller for this thing. I don't know much about this controler, but I'm certainly interested in the infrastructure parts.
