On 10.04 LTS my little Dell D600I could use PAE-Kernels with no
problems. (36-bits) . As per today it runs with the Mainline Kernel
3.10.7-031007-generic - lawlessly.  Thanks to Prof7bits "Fake-PAE"

And this confirms comment #179:
... the Linux documentation states that if you can boot a PAE kernel, then your CPU has PAE. If you don't have PAE, then the kernel won't even boot.

Simple as that. Don't argue wt dev's why priorize the non-PAE over the
PAE. see also
https://en.wikipedia.org/wiki/Physical_Address_Extension#Linux . It's an
non-arguable decision, even though anyone wt. a RAM > 4GiB should decide
for a 64-Bit system. :-)

If the Kernel naming would clearly state it's a PAE, since the other
Kernel's part was removed, we would probably not need a preinst. script
to drag people away Ubuntu, even from other flavours. Like Elementary-OS

Well, if Intel thought they shouldn't equipe some Pentium M with a PAE
flag (even though it's capable) they deserve a bug-report. And should
publish a new updated BIOS. They always had open ears to Linux users.

 It's the old linux-users desease working rather on the effects than on
the impact.

Nowadays I need to edit & manipulate the downloaded CD for an
installation? That's possible & ends up with ISO-start in GRUB2. This is
Not o.k.! Pls support bug#1214462 –   " Kernel Description doesn't
explain its a PAE-Kernel _ since 3.4.0.1.1 _ Linus would not smile _. "

Title:
  Unable to start Ubuntu 12.04 live CD with syslinux loader on Pentium M
  x86 Laptop due to bug in PAE kernel, initramfs or syslinux

Status in “linux” package in Ubuntu:
  Won't Fix
Status in “syslinux” package in Ubuntu:
  Fix Released
Status in Baltix GNU/Linux:
  Triaged

Bug description:
  Ubuntu 12.04 doesn't start from Desktop CD or USB with syslinux boot
  loader on Pentium M 1.6Ghz or faster Pentium M CPU - displays error
  message about missing PAE feature in CPU, but *the same* *Ubuntu
  12.04* Desktop CD/LiveUSB starts fine on *the same CPU* (and same PAE
  kernel) if GRUB boot loader is used, for example when WUBI or LiveUSB
  with GRUB boot loader, like Multisystem
  (http://liveusb.info/dotclear/index.php?pages/install ) is used!

  The error message is:
  "This kernel requires the following features not present on the CPU: pae.
  Unable to boot - please use a kernel appropriate for you CPU."

  THIS IS AN IMPORTANT REGRESSION! People are able to install and successfully use Ubuntu 12.04 on such pretty new hardware, like IBM Thinkpad T42 laptop with Pentium M 1700Mhz processor, but the bug in syslinux (or something related) forbids Ubuntu 12.04 installation.
  This bug is reproducible on lots of computers, there are several log files and /proc/cpuinfo file attached to this bugreport, AFAIK it's enough to reopen this bug.
