There are a fair number of DIP switch settings as I recall. I know in my case that the XT-CF conflicted with the address of my ethernet card, and I ended up changing the ethernet card address. And from there I didn't change any settings on the XT-CF card.
I think these are all about the same, you can choose address, whether or not to enable/disable the EEPROM (rumor has it that you could put the EEPROM on an ethernet card and boot that way), etc. Here is one card with settings: http://www.malinov.com/Home/sergeys-projects/xt-cf-lite
