View Full Version : [SOLVED] Pentium M 1.2 GHz, 640 MB ram: Neither version of 12.04 installs

December 22nd, 2013, 03:50 AM
I am trying to upgrade from 11.04 by doing a fresh install of 12.04 on this older Dell laptop.

But I can get neither of the offered 12.04 versions to install.


Both get an error "this kernel requires an x86-64CPU. But only detected an i686 CPU"

what can I do?

Stick with the i386 and forget the amd64. Sounds like you have a single core processor.

More information would help, for instance the specs of this older laptop, when you receive this error message and what happens after it, and anything you have tried so far to remedy this.

For starters, though, try the i386 alternate ISO. The same but text based so no disco bells and whistles. This can succeed where the desktop version fails. Same end result.

the i386 iso is not working.

With only 640Mb of RAM you cannot install regular Ubuntu, as it needs more RAM to work with amongst other requirements.
Your best bet is Lubuntu Minimal Install (https://help.ubuntu.com/community/Lubuntu/Documentation/MinimalInstall).
If your systems support more RAM then, if possible, add more RAM.

Good Luck...

Or just a minimal install and add any one of the lightweight desktop environments, lxde or xfce or any of the many others.

Yes, Lubuntu Minimal is a good option.
Here's a solution if you encounter PAE (https://help.ubuntu.com/community/PAE) problems.

Indeed, I hit the PAE problem when trying to install Lubuntu.

tell me though, I have a reasonably functional version of Ubuntu 11.04 running on this unit. Why should I continue fiddling with upgrades or better versions? Why should one care if support has been ended?

Because there will be no security bug fixes (actually you have been vulnerable for more than a year).

Why not give it a fresh install of Bodhi?

just installed Bodhi now and am fiddling with it. But My Goodness, what a slick little setup this seems to be. And everything just ... works. wireless and all.
many thanks for your guidance and patience.

Yea, have been playing with Bodhi in virtual box and really quite like it, too.
