Kai: Yes, I rebooted, very early this morning. I just tried it again. My
wife had been using MS Windows XP. I rebooted the box into CentOS 5:

What you describe above is how it works on my box and on my daughters
box. They are working correctly. However, on my wife's box (compaq1300)
there is a glitch, that is causing this not to work properly. On
compaq1300, I do *not* have the three boot options (original kernel,
latest kernel and Windows XP). I have two (2) options, if I interrupt
grub:  (a) the original kernel (b) other, which is Windows XP

As CentOS 5 boots, it shows, a number of times, the original CentOS 5
kernel, that is on the Install DVD I got last year. At *no* time, does
it show the latest kernel booting.

Yes. The 3 Desktop boxes are dual boot. CentOS 5 and Windoze XP.
Grub is installed on all 3 boxes.  Of the 3 boxes, 2 of them are working
properly.   :-) Have a nice evening and thank you! Lanny
