Making Upgrades possible

Add the PAE flag to processor information
To add the PAE flag to the processor information stored in /proc/cpuinfo, run the following:
      cat /proc/cpuinfo | sed 's/flags\t*:/& pae/' > /tmp/cpuinfo_pae
      sudo mount -o bind /tmp/cpuinfo_pae /proc/cpuinfo
      sudo mount -o remount,ro,bind /proc/cpuinfo 
After you have ran those commands, run
 grep flags /proc/cpuinfo 
If the flag was correctly added, the command returns a line that starts with “flags :” and contains the flag “pae”.
