How I know if my computer is 64bits?
Right now I have Ubuntu 12.04.2 LTS (GNU/Linux 3.5.0-28-generic i686).
Is there any command that let me know if I'm able to install Ubuntu Server 64bits?
The purpose of this move is that I have 4Gb RAM (2Gb X 2) and 32bits only read 3Gb...
Other Specs from my computer:
Model: Dell Optiplex 210L
Intel Pentium 4
A friend told me about using PAE but I'm not familiar with the process. If somebody can help me with this I'll appreciate.
