Two XP machines, both with ethernet cards.

I heard that modern Ethernet cards have an option to switch into crossover mode. Can I do this through device manager or do I have to move jumpers? Is it even possible or did I just imagine it?

I think you may have misunderstood... a lot of modern *routers* (and hubs, switches, etc) can autodetect the type of connection, so you can use either a straight cable or a crossover.
If you're just connecting two machine directly, though, you'll need to use a Xover, since the NI cards don't usually do that autodetection.
Just a tip.. get some brightly coloured labels and write "CROSSOVER" on them in big letters, stick them to the cable. It will save you a lot of pain later, when you just grab a random cable out of the box and wonder why it's not working.... Been there, done that...:-)

Cross over cabling is just a type of wiring. There is no setting on the card or any hack that has to be done. It is absolutely straight forward. The way you crimp the wire connecting the computers only does the trick.
You can however only connect only two computers together.
As with cross over cabling, you would notice that your Lan card has a RJ45 connector with eight wires. (Four Pairs) Two pairs are used of these, one for input and the other for output. On a straight cable, in on one side is in on the other end. ie, the used for input in the jack will be used for input. Crossover is just the opposite. Input on one Jack is output on the other. So data literally just reaches the other connection. All the hubs and switches do it internally.
As advised in another post, turn off all firewalls.
Regarding the connection, you can find more information. I used http://www.netspec.com/helpdesk/wiredoc.html to get the details of the wiring
The two ends look like this:
Standard End Crossover End
Pin 1 White/Orange Pin 1 White/Green
Pin 2 Orange Pin 2 Green
Pin 3 White/Green Pin 3 White/Orange
Pin 4 Blue Pin 4 Blue
Pin 5 White/Blue Pin 5 White/Blue
Pin 6 Green Pin 6 Orange
Pin 7 White/Brown Pin 7 White/Brown
Pin 8 Brown Pin 8 Brown

Not saying its not possible but I've been in IT for 15 years and never heard of a ethernet card with a "crossover" setting.

In order to connect two computers directly without a hub you will need a crossover cable, or a regular cable with a crossover adapter.

You must have a crossover cable for pc to pc connection. Hoever if you can not get one and you need to connect them, then use a router to set up a local network. Connect to the pc directly via ip address. Make sure you turn off all firewalls.
