If you are used to LILO, it still exist in CentOS4, but isn't the 
default boot loader.  You can specify it during the installation, or you 
can remove grub and install LILO later on.  It handles /boot on RAID1 

If you want to continue using Grub, this post from Fedora mailing list 
might be helpfull:
