Kernel Flavor and How to Set It?

I am trying to understand what is Linux Kernel Flavor and how to set it? Is it through command line or is there a configuration file I should change?
Specifically, here is it the situation:
I have installed Linux Enterprise Server 11 SP2 and now I want to install its Real Time extension. As a newbie I have downloaded the ISO files, and now I am trying to follow the instructions:
The first instruction from the guide is:
select the -rt kernel flavor as the default using the YaST Boot Loader configurator
I have entered the Boot Loader configurator but couldn't find any kernel flavor options.
Can anyone tell how to find and select this option?

"kernel flavor" is a term used to represent the kernel version number. Go back to the YaST boot loader configurator and look for the kernel version number to use.

I went to the YaST2 Boot Loader Settings and into the Section Management.
There I saw the Kernel Image which had the value /boot/vmlinuz-3.0.13-0.27-default.

Is that the flavor they mean?
If so, how do I change this to -rt?
Do I just change the name to /boot/vmlinuz-3.0.13-0.27-rt ?

Obviously changing the name of a file would in no way change what is stored in the kernel. I have not done what you aer attempting but my guess would be that you need to reconfigure the kernel to contain the real time extensions needed (again I am not sure which these are but maybe your instructions will help)

Sorry for my ignorance.
The problem is that I haven't read the manual correctly. I had to first install the CD as mentioned in the guide, and than it automatically added the flavor to the available options.

Thank you for your patience.
