I have all RH's from 4.2 to FC4.  I am a bit concerned about the linux I put
on it knowing how to run the RAID controller and SMP ability, hence asking
the wealth of knowledge that I know exists within MW. 
 
Later RH, as well as Fedora will recognise the SMP system and install a SMP
kernel with no fuss.  As for the RAID, identify the controller and look up
the hardware related HowTos.
