I downloaded the 32bit 12.04 and burned a CD but when I boot on my older laptop with a Pentium M CPU I get the error "This kernel requires the following features not present on the CPU: pae Unable to boot - please use a kernel appropriate for your CPU."
Have I got the wrong iso? or maybe 12.04 won't work on this laptop.
yup you need to down load one of the other ISOs you need 32bit with pae which as I understands it is fakes 64bit allows your computer to access and address more then 3 gb of ram ..
Thanks I will see if I can find it.Quote:

See this page for help: http://www.webupd8.org/2012/05/how-t...n-non-pae.html
oh the reverse I didn't catch that ..
actually thought you have to go out of your way to the list of sites to get ISO 32 bit with pae the same with the alternate iso ...
in that case try the non-pae mini cd. it a txt based install boots like any other CD

Another distribution might serve you better given the older hardware (Lubuntu or Xubuntu). This is from the Precise release page.

The Ubuntu 12.04 installation image does not include support for old computers that do not support PAE. If your computer is affected, you can either first install Ubuntu 10.04 or 11.10 and upgrade to 12.04 or you can use the Lubuntu or Xubuntu images. The non-PAE version of the Linux kernel will be dropped completely following the 12.04 release.
not a lot of info for this lap top given but my search shows that the Pentium M CPU support 512 mb of ram 1.4ghz processor so this would work with 12.4 fine thing is the docs clearly say the best way to do this now is upgrade from an older version ..
the mini non pae cd should still do it as long as they aren't put off by the txt based install ..
also if they can find a ISO for 12.4 beta 2 this would work as well the pae support was not dropped till the release version ..
also wubi installer would do the trick as well since its still 11.10 then you can migrate that and upgrade ..
The Pentium M and derived Celerons do not support PAE (I have one).Quote:

If you want Ubuntu 12.04 you will have to install from the mini-iso cd image which has kernel support for non-PAE CPU'sQuote:

I would suggest you download the Xubuntu cd image and install that and see how you like it, if you still want you can then install Ubuntu from there easily, all you have to do from a terminal is:
and afterwards edit one file:Code:sudo apt-get install ubuntu-desktop
so the file has this specified,Code:sudo leafpad /etc/lightdm/lightdm.conf

Thanks for all the help on this one. For now I am going to stay with 10.10. I am just using this old laptop on a sound system with audacity. The problem I was having was audacity would lockup once in awhile so I just reinstall it. I hope this will fix the problem, but I have a feeling it is a hardware issue. The screen blinks when it locks up. It goes black and then comes back on and at that point audacity is locked. Actually it is the recording that is locked, I can export the recording to a mp3 file and restart audacity and start recording again and everything seems to work again. Time will tell if reloading audacity fixed the problem.
Again thanks for the help.
