This OSX version cannot be installed - SL Server

Hi guys, I have a white MacBook here that I upgraded the hard drive to a bigger size, and I'm trying to install Snow Leopard Server on it. I keep getting an error "Mac OSX cannot be installed on this computer." I read some other posts on here where people said you have to create a 5GB partition for it to work, but that didn't do the trick for me. Could it be because I'm trying to install the Server version, or should that matter? Thanks

What are the specs for the White MacBook? And what kind of Snow Leopard server disk are you using? If it's model specific, it may not work.
