Hi again Israel,

On the other hand, I think there are so few non-pae machines that you
might skip them and cater for the Pentium M and Celeron M processors
with trusty's built-in forcepae boot option.

I have searched for real non-pae machines via the Ubuntu Forums and it
is almost impossible. But there is a fair number of 'fake-pae' machines
(with Pentium M and Celeron M processors that have pae capability but
lack a pae flag), even though they are also getting scarce as years pass by.

https://en.wikipedia.org/wiki/Physical_Address_Extension

'PAE was first implemented in the Intel Pentium Pro in 1995,[1] although
the accompanying chipsets usually lacked support for the required extra
address bits.[2]'

So I think it is enough to have a non-pae kernel in ToriOS 1, which will
get updated packages until April 2017 (22 years after pae was introduced).

-o-

Finally, I think it is very important to discuss this item at the ToriOS
Saturday meetings, so that the active members at the meeting agree what
to do. So I cc this mail to torios-dev. Now you know what I think about
it :-)

Best regards
Nio
