Hi George,
I think you need a non-pae operating system in order to run in a
computer without pae capability. Otherwise it will not work at all.
Maybe that system could be a mini-system alongside a pae system or
64-bit system (and available via a grub menu or syslinux menu.
But there is also the issue with the CD size - it is hard to squeeze all
we want to include into 700 Mibibytes, so it would not be popular to add
a separate system (even if it is small).
I think a good solution is to have a very small system in a separate CD
or USB drive, and boot the system into that system and try. A Tiny Core
iso file is only around 15 MB, so very light-weight to download.
1. Boot Tiny Core
2. Open a terminal window
3. Run the command
grep pae /proc/cpuinfo
and look for a line containing 'pae'. If there is such a line (or
lines), you have pae capability.
4. Run the command
grep model /proc/cpuinfo
and look for Pentium M or Celeron M. If there is such a CPU, most likely
you have pae capability even if there is no pae flag. It means that you
can use forcepae with distros based on Trusty (14.04 LTS) with a kernel
of the 3.13 series and distros with newer kernels.
-o-
Pentium II, Pentium III and Pentium 4 all have pae (flag and
capability). Also the contemporary Celeron processors and AMD processors
have pae.
Examples of non-pae CPUs
Early Pentium M with 1.2 GHz clock frequency. The later Pentium M CPUs
have PAE capability even if they lack a pae flag.
Old ViA-processors around 1GHz
Transmeta Crusoe
Pre Pentium II CPUs are too old and weak for ToriOS anyway
Best regards
Nio

no,
i dont mean to include a non-pae working system in all distros,
just for an error message to pop up
saying what the CPU is
and which distro would work.
(i am not a hardware expert)

Is it possible for the install CD/USB stick
to first scan the computer
and post up a message if the CPU is unsuitable
with recommendation for what distro would work.
I wish Ubuntu etc would do this
for non-pae CPUs

There are hardly any non-pae computers left. The boot option
forcepae in
Ubuntu 14.04 will provide a solution for Pentium M and Celeron M CPUs,
and in the very few (if any) remaining cases, we can offer ToriOS-Debian.
I suggest that ToriOS 2.0 will have an Ubuntu 14.04 LTS, 'Trusty'
version instead of Ubuntu 12.04 LTS (precise). I agree that there should
be a Debian Jessie version too.
Hi George,
I think this is difficult to scan the computer like you want unless you
provide the most primitive version (non-pae), and it is probably the
reason why it is not implemented already i Ubuntu.
Does this mean that you want to keep the non-pae live system in all
future versions of ToriOS? I think it is enough in one of the future
versions (Debian).
Best regards
Nio
