I need basic help networking 2 computers

I got mysef into somethign I thought I could do but managed to get lost! I have an HP Pavilion 8570C and an PB Axcel 2420. I installed a network card on both of them. I am using a crossover cable to connect the two and I am getting a link light on both of them! Now my problem is I can not figure out where to go to map the network on each computer (I know, basic stuff for you guuys probably!) The PB has Win 95 and the HP has 98 which may help anyone who responds. I really hope someone can help because this is really important to my business. Thanks
