firmware drop down choices in PncConfig for 7i96s?

i had a chance to poke around with the PnCConf for my 7i96s and seen 3 choices for firmware on the drop down selection, my question is what one to use? One other question would be the IP address if i change things to the 10.10.10.10 the jumper on W5 needs moved to the up position and the W4 would stay down if my assumptions are correct? i don't have this computer connected to the internet and don't plan to hook it up but i did have it hooked up to install the Linuxcnc. So by going to the 10.10.10.10 IP would avoid any potential conflicts if something weird where done during the install right?

Thanks in advance.

7I96S_d would be the normal choice

For 10.10.10.10 you set W4 down and W5 up
(and cycle the card power)

10.10.10.10 is suggested so it does not overlap
with normal DHCP IP address ranges of local networks

thank you for such a fast reply PCW that was the answers i was looking for.

How can I find the version of the FW currently in my 7i96s and what is the FW version that I downloaded? It seems both are missing. Thanks.

Not sure what you mean by version.

There are versions of all the sub-modules plus
The Ethernet ROM version, normally these are
only of interest in special cases.
