Kai: Before I got the above data this morning, I let PUP
download/install the latest kernel (2.6.18-53.1.19.el5.i686) but after
rebooting, it comes up with the original kernel that is on the CentOS
5 Install DVD I used last November. Not surprising that it does not
boot this newest kernel. The download/install seemed to go perfectly,
so the "Subject" changed from yum not updating the kernel to where is
the proper boot file.... When it boots Linux, CentOS gives a message
something like booting root (hd 0, 7). TIA, Lanny
