12.04 Beta1 is PAE support only

[lophiomys]

The Desktop i386 CD and DVD images of 12.04 Beta1 are PAE support only..
This excludes at least Pentium M Dothan with 400MHz FSB, e.g. Thinkpad T42p.

Will there be a non-PAE kernel available later on?
Or is the alternate install version for non-PAE CPUs?

Here's the discussion on the Ubuntu developer's list -

And my own two cents -

Precise is an LTS release, which means they'd be supporting non-PAE kernels for another five years if they supported it in this release. I understand that affects some of the Pentium M crowd, but I can understand why they want to draw the line here.

- Will non-pae kernel be available in Precise?: https://answers.launchpad.net/ubuntu...uestion/187093

- How should Pentium M users install Precise?: https://answers.launchpad.net/ubuntu...uestion/187166

(1) Upgrades from Oneiric w/non-pae to Precise remain non-pae, so those performing upgrades should be OK.

(2) Using the non-pae mini.iso should work:

- mini.iso is: https://help.ubuntu.com/community/In...tion/MinimalCD

The Minimal CD will download packages from online archives at installation time instead of providing them on the install CD itself.

I have our thin clients at work running 10.04. They have AMD Geode, and won't work with 12.04. I guess if I update them I will have to roll my own kernel. No big deal. I generally recompile the Ubuntu kernel for the work machines anyway. I worry about the Lubuntu/Xubuntu crowd. They generally use older hardware that will be affected.

I have a Dell Inspiron 630m laptop, which has the pentium M processor. Is this the last version of Kububtu that I will be able to use?

If you use the mini.iso from the link above to install 12.04, you can get around the PAE requirement, as that uses Ubuntu kernel version 3.2.0-21 generic without the PAE requirement. I just installed it on an old Pentium M HP laptop without issue. It's just like the Alternate install disc (text-based installer) except the .iso is only 24MB in size! So you'll been some bandwidth to download everything. Took me a few hours to do a fresh install.

*Note* The install *appeared* to hang when it got the network-discovery step. I let it sit for about 30 (yes 30) minutes and it finally went to the next prompt. No idea why it stayed on that step for so long...

That's good to know. I've never used that image for Ubuntu. I always strip it down anyway.
