Moving from 32-bit kernel to 64-bit kernel

I have been running F14 as a 32-bit system (original m/b was 32-bit). Now the system is on a 64-bit dual-core processor board and I'd like to change from the 32-bit kernel to 64-bit.

I downloaded a 64-bit kernel (kernel-2.6.35.6-45.fc14.86_64.rpm) and attempted to install it. It won't install and Package Installer returns a message of the sort that says this file "has incompatible architecture. Valid architectures are ['athlon', 'i686', 'i586', 'i486'....]". My processor is an Athlon 64 x2.

Is it possible to do what I want to do (I only want the kernel at the moment)? Is there some Fedora file I need to modify to allow the system to install the 64-bit kernel for this m/b? Do I need another file (or files) installed before I install the kernel? Something else?

Thanks in advance for any help and guidance.

Cheers....Steph

Re: Moving from 32-bit kernel to 64-bit kernel

To convert from 32 bit to 64 bit you have to do a fresh 64 bit install, you can not simply install the kernel.

Re: Moving from 32-bit kernel to 64-bit kernel

Interesting. I thought maybe it might be a boot issue (I could only hope).

In a previous thread (I was trying to fix an F14 problem at the time) I raised this same question (about moving to 64-bit) and the response I got was that I only needed to download the kernel. His sense was that the 64-bit kernel would play with the 32-bit tools and applications. Apparently not true. Bummer!

So, since F15 is out, is there a way I can upgrade to Fedora 64-bit and not lose any (or much) of my existing system and environment (as I would expect with a 32-bit upgrade)? Or, are we talking a "flatten the drive and start from scratch" scenario.


Thanks and cheers...Steph

You can save your data and configuration files, but as F15 is gnome 3 I would go for a fresh install and restore any data from backup.

Re: Moving from 32-bit kernel to 64-bit kernel

Thanks again. I understand your suggestion. Any easy way (maybe some configuration file) to ensure I get back any programs I've "added" since...well...forever Or, does that need to be a manual process?

Cheers....

See if this thread helps :

Again if there is a specific configuration file you know you want, such as ~.bashrc, back it up.

If it is just "generic" configuration files for themes, I would not bother.

Re: Moving from 32-bit kernel to 64-bit kernel

Again, thanks for the help and info. The link is exactly what I was looking for. I want to make sure I can reload all the applications currently on my F14 32-bit system.

Cheers....Steph
