If you run the PAE kernel, then all of your memory will be seen and
used by the OS. It is what I use when I use a desktop system so that
I do not have to deal with x86_64 type desktop issues.
I am now running it, seems fine. Now if we could figgur out why grub takes
about a minute to present the boot menu.
I did just now update the bios, and now the blinking display if using the hdmi
cable for about the first 5 minutes seems to be gone.
Thanks.
