My current kernel is as follows;
CentOS (2.6.18-53.1.21.el5)

I need to remove preemptive multi-tasking.  What is the easiest way to do this?  I assume recompiling the kernel is in order?  Any suggestions?

Thanks

I have looked at those previously and have had experience compiling a kernel in the past.  I just am not sure how to remove/disable preemptive mulit-tasking.
