I tested the Ubuntu Vivid daily 32-bit mini.iso (dated feb 9) in my IBM
Thinkpad T42 with Pentium M, and it works for me too with this double
boot option.

I clicked tab to get to the boot line.

I edited the boot line from

> linux vga=788 initrd=initrd.gz -- quiet

to

> linux vga=788 initrd=initrd.gz forcepae -- quiet forcepae

and the installation of a minimal text system worked for me.

Thank you very much for helping us to solve this problem, Chris :-)

Is this new usage of boot options general?

1. The entry before -- means that it will be used by the live system /
the installer

2. The entry after -- means that it will be carried to and used by the
installed system

Title:
  No installable kernel was found in the defined APT sources

Status in linux package in Ubuntu:
  Invalid

Bug description:
  I tried to install from the Ubuntu Vivid 32-bit mini.iso into a
  computer with Pentium M

  http://www.cnet.com/laptops/lenovo-
  thinkpad-t42-2373/4507-3121_7-31155666.html

  and booted the installer with the forcepae boot option. This made the
  installer start and work until it should get the kernel. Then it
  stopped with the following message

  "No installable kernel was found in the defined APT sources ...
  Continue the installation without installing a kernel?"

  I checked if this is a PAE issue ... and yes, it is.

  Forcepae makes the installer work, but later on, during installation,
  it refuses to manage the [PAE] kernel. I tested, and it works in a
  computer with CPU with a built-in PAE flag. And the trusty mini.iso
  can install in the same computer with Pentium M, so this is a
  regression.

  At 'ctrl+alt+F4' it complains that the kernels found are not usable on
  486. But forcepae should allow it. And the same kernels work when
  installed with the corresponding daily Lubuntu Vivid desktop iso file.

  This bug is reported from another computer, because I don't know how
  to report it from the mini.iso system. So you should disregard the
  collected data, that I might not be able to remove.
