Hi, My machines (IBM ThinkPad T41, Type 2373-9EU) all claim to be Pentium-M and do NOT support PAE according to the Ubuntu boot message. I do have 2GB (the max without PAE) of DRAM installed.
How much simpler is life with PAE-only support? (Since that is the path that was taken, I am hoping that the answer is very trivial to quantify since the work was done and the code base reflects that change). I understand moving ahead, but, to me, this fairly capable 32-bit machine should still be supportable by Ubuntu. I have not tried using CentOS as my desktop yet, but maybe that is an option if I can't get the next LTS (14.04) Ubuntu to boot straight up. Cheers, --ldl ldl@boGus:~$ lsb_release -a No LSB modules are available.
