Downloading v4

[kevin.kempter at dataintellect.com (kevin.kempter@xxxxxxxxxxxxxxxxx)]

Hi List;

I see in the 4.2 downloads area the following:
[   ] CentOS-4.2-i386-bin1of4.iso      11-Oct-2005 13:07  618M  
[   ] CentOS-4.2-i386-bin2of4.iso      11-Oct-2005 13:13  635M  
[   ] CentOS-4.2-i386-bin3of4.iso      11-Oct-2005 13:20  639M  
[   ] CentOS-4.2-i386-bin4of4.iso      11-Oct-2005 13:22  217M  

[   ] CentOS-4.2.ServerCD-i386.iso     07-Nov-2005 04:36  558M  


What is the 4.2ServerCD ? 

I plan to download the 4 bin cd's and load the os on a sony vaio laptop. Do I 
also need the server cd?
