[NBLUG/talk] Need help with booting Linux system

Sorry I was not clearer in my response.  Several days ago I ran

rpm -Uvh --replacepkgs --replacefiles 
kernel-2.6.9-100.EL.i686.rpm 
redhat-logos-1.1.26-1.centos4.4.noarch.rpm grub-0.95-3.8.i386.rpm

However, I have not tried to reboot.  With the help of Scott and 
others, I *think* I have the /boot and /boot/grub directories as 
close as I can get them to be "boot ready".  So, I am waiting for 
a good time to "pull the trigger" and try a reboot.
