[CentOS] Can CentOS 4 be installed from CD1 only?

Hi. I'm installing CentOS far from home and forgot the CDs... I don't 
have time to download all 4, what are my best options? I can download CD 
1 and perhaps 2 - is that enough? Is there a way to install directly 
over the internet from one of the mirrors?

Thanks.
