Yes, JP1 is a jumper block.Not entirely sure what you mean by jumpers or what they do but i know i have the JP in this picture (should be near top middle).
There are 4 positions, as described in the 'Board Configuration' section of [here]. 'Open' means that no jumper is fitted; 'closed' means that a jumper is fitted. The blue things are jumpers. So, your card, as expected, is configured for the defaults, which includes the card (card, not XUB) being configured for a base I/O port address of 300h. So, we can rule out a missing jumper on position 2 as the reason why your XT-CF-lite rev.2 card is not 'seeing' the CF card.
