Hi, all.

I wonder whether it is possible to use retain Vars on SL product(except embedded board), if I install extra NVRAM(PCI card type).

It depends a bit of the card that is used. Currently you can configure the runtime to use a fix memory mapped NVRAM, when the memory is mapped to a fix address, and behaves similar to a normal RAM.
