I think the main issue is the PAE flag. I did mean the opposite. Installing on non-pae for the older laptops that don't set the flag in the processor. Like 12.04 Lubuntu offering a non-pae installation option. Can this be done in OBI by using a pae kernel on a non pae? as in, the very last section (C) on this page... https://help.ubuntu.com/community/PAE So does the whole non-pae issue arise from a flag that a processor doesn't set, even if it is PAE. I am trying to understand whether or not we can install trusty on a non-pae flag computer with a normal (in the repos) kernel, or whether we need to use Precise to do precisely this :) OR, is it possible to use phillw's kernel and have it stay up-to-date in trusty? Or is it needed only for the Live image? I hope I am more clear, but it is hard to mush my thoughts back together :) And I don't entirely understand the pae issue. > I can also run Phill's non-pae kernel in my Toshiba with Intel i5 (which > has 64-bit architecture).
