What data are you trying to protect? Is it in your /home user area? How is your system currently partitioned? I suggest backing up the machine to cd or dvd prior to attempting anything.

If you're only upgrading the kernel (to 2.6.xx ?) then you can keep your old kernel in case you have problems booting the new one.

And you can download the kernel source.

Or do you want to dual-boot RH and RHEL?

Not sure what you really want to do.

This is true both kernels can coexist in the /boot fs. Are you using grub or lilo as your boot loader? I still strongly suggest backing things up as a percaution.

ok... i agree in for taking backup... But reinstalling will be waste of time... So i want to know whether there is any alternative... Is the source code for RHEL 4 kernel is available anywhere?

The source code for RHEL kernel is probably not freely available - I think you have to pay for it. If you do find it though it will likely be in the form of an src.rpm file.

Alternatively, you can download the source for a newer kernel from here

http://www.kernel.org/pub/

Then find a good guide if you're not familiar with the procedure, and compile it yourself.

For less than $200 I was able to find a pocket-sized USB hard-drive that holds about 80 gigabytes. (Try searching Amazon for "datastor.") Some of the units advertised hold considerably more.

This will give you a very-reliable "place to put your data," such that no matter what you do to the data on the hard-drive, the essential stuff is entirely safe (as long as the drive has been dismounted and unplugged from the USB-port). The drives normally take power directly from the port. If you have USB 2.0, they run at very high speeds; USB 1.1 is downward-compatible even if not mentioned. Linux USB storage drivers recognize and handle them just fine... so does Windows, OS/X and everyone-else.

This will be well worth the investment... I use them as a primary backup-media and keep one in a safe-deposit box. It enables you to approach the task "with nothing to lose."
