Couple of things here.  What sort of crossover cable are you after, to connect two network cards so you don't need to use a hub or are you talking about a standard port crossover cable for the lpt1 port or a null modem cross over for the serial port.  Also colour codes differ from country to country and some cabling doesn't even use different coloured internal colours.
From http://www.silk.net/personal/lwright/hwb/hwb/ca_Ethernet10BaseTCrossover.html

Name NIC1 NIC2 Name
TX+ 1 3 RX+
TX- 2 6 RX-
RX+ 3 1 TX+
RX- 6 2 TX-

The above is the standard pinout configuration for CAT 5 cable used in a crossover.  Suggest you visit the URL for a better description with pictures.

If you have connected the cable properly then..

Goto Network Properties and install TCP/IP protocol which is better choice then NetBEUI.

* Goto TCP/IP Properties for the NIC Card and specify IP Address ( Class C ) as 200.1.1.1  and 200.1.1.2 and specify the Subnet Mask as 255.255.255.0 (same for 2 PCS)

IP Addresses need not to be the same but the Class should match with subnet mask.  




*Then goto Identification tab and give a Workgtoup name (shuold be same on both systems) also Computer Names (unique).

*If you want to share Data and Print then add serice >>  File and Print Sharing for MS Networks

* Also click File and Print Sharing Button and Check both the options given.

Give OK and  restart the systems.

That's it !

Good Luck

If you have connnected the same way ,what you have mentioned above then
just connect it.

No need for any Hub.

You can connect directly both the NICs.

The crossover cable is correct.  You may need to make sure that you have connected the RJ45 connectors properly however, if you didn't use the correct tool this can be tricky.

One other note:

The IP addresses SHOULD NOT be the same.  You will get errors if you attempt to connect computers with the same IP address, also there are three specific IP address ranges for use on private networks and these should be used.  The most common is 192.168.#.#.
