Introduction

PAE (Physical Address Extension) is explained here in details.

Bento-fake-PAE offers a method to install Bento Remix into computers (mainly if not only laptops) with Pentium M and Celeron M CPUs. Most if not all of these CPUs have PAE capability, but show no PAE flag. This means that these machines can not use any Ubuntu based versions after 12.04 and therefore, Bento with a new kernel can not be installed and their kernels can not be upgraded, because the software is checking for the PAE flag. This can be fixed with fake-PAE, developed by Bernd Kreuss prof7bit and described in the Ubuntu Forums.

There are many high-quality professional class laptops around with Pentium M CPUs, for example IBM Thinkpad T40, T41 and T42.

Three methods are described to make the new Ubuntu family 32-bit PAE kernels available for Pentium M and Celeron M, that have PAE capability, but do not show the PAE flag.

LinuxVillage Bento Ubuntu Remix

The Linux Village Bento Ubuntu Remix is described at the following web page

http://linuxvillage.org/en/2013/11/bento-ubuntu-remix-rc/

Bento Fake-PAE

The idea is to make it easier for people who want to go directly into a new version of Bento. This is a good alternative for a fresh install (instead of starting from 12.04 and upgrading twice to newer releases).

Right now the image file to download resides on this link

http://phillw.net/isos/lubuntu-fake-pae/raring/grub-n-iso and will be available at

http://phillw.net/isos/bento-ubuntu-remix/

Test

See the description at https://help.ubuntu.com/community/Lubuntu-fake-PAE#Test

Helpful members of the Ubuntu and Lubuntu communities have found that fake-PAE works with almost all Celeron M and Pentium M, and the instructions have been improved.

With your help and support we might be able to add CPU IDs to the list.

'grub-n-iso'

Detailed description

You find a detailed description at grub-n-iso

That page was written primarily for Lubuntu fake-PAE but the information can be used for Bento too.

Advantages

Similar to normal installation (via 1GB or 2GB USB drive)
No upgrading between versions is necessary
Full flexibility, for example to make a dual boot system
The standard Bento Remix i386 iso file is used, and can be checked with md5sum

according to http://linuxvillage.org/en/2013/11/bento-ubuntu-remix-rc/

Disadvantages

You must boot from a USB drive or a second hard disk drive (CD/DVD cannot be used)

Warning

This Bento 'grub-n-iso’ system was made for Pentium M and Celeron M, that have PAE capability but no PAE flag. It is harmless for all computers modern enough to have USB. We take no responsibility for any damage, that this software can cause with very old hardware without PAE capability (pre Pentium II).
