Hello,
It has been a while since I've been more than a casual user of Linux, but I
was wondering what the advantage would be of running ia32 with PAE versus
native 64-bit (x86-64 or amd64?)? Is there something which is more efficient
or better about using it for certain tasks? The last time I worked with
Linux it was on embedded systems, and 8MB of RAM was considered "large."
Regards,
Aryeh Goretsky

I won't bother googling since I don't care about Windows. I just wanted
to set the record straight w.r.t the "need a 64-bit operating system to
take advantage of more than 4GB of RAM".
