Changing kernels


I am running Red Hat 8.0, booting from a floppy....Machine tells me that I am running kernel xxxxxxxxx, reboot to run latest installed kernel....
How do I tell it to run the latest installed kernel?????? When I reboot I get the same kernel 2.4.18.14
The latest installed kernel is 2.4.18-27.8.0
Linux is installed on the second hard drive, first hard drive has Windows ME and also Windows 98. I have Bootmagic installed on the first hard drive, from which I boot the Windows versions

what tells you to reboot to use the latest kernel?

if you have a kernel and not the option to boot into it reconfigure lilo by editing /etc/lilo.conf then rerun lilo to save the new configuration.

let me know if you need more detailed info.

Aha!!!!! Well, when I installed Linux I did not install Lilo or Grub (since I did not want to mess with the MBR. Soooo, as I said, I boot Linux from a floppy. What specifically tells me to reboot I do not know...I will check. It does not seem to do it all the time, but when it does, a window pops up and tells me that I am not running the latest "installed" kernel. I did upgrade the kernel at one time using "up2date" from Red Hat. My Linux installation is on a separate hard drive from the other OP systems, and I am booting from /dev/hdb5. Thank you for your help!!!

not sure I understand... I realize you're booting from a floppy... does the boot disk boot right into the old kernel... without letting you pick one?

Yes, that is correct...the boot disk just "does it"...as I remember, from long ago with another installation, I used to get the chance to select the kernel....but not with this one.

so create another boot disk with the new kernel

do this by typing at a command prompt
mkbootdisk <new kernel filename>

for help on this look up the man page for mkbootdisk

The little red button is for the up2date. It connects you to the RHN so you can get the latest packages.

Regards

Yeah, KennyK....but it doesn't update my boot diskette, so that was why I was getting a message to "reboot" to the latest installed kernel...
