6.2 Installation

Hello When I installed SuSE 6.2 into my machine I found that when I booted it after installation I got a PGP signature and a request for login. I've since found a message which says that my kernel is not verified. I found this by chance. Does this mean that I am supposed to check my PGP signature against the kernel and vice versa ? I can't find anything in the SuSE 6.2 manual about this so I need some help. Thanks Richard Sheffield UK
