When I try to enable the PAE switch in boot.ini nothing happens. I save the file and reboot, then reboot the system again to install Lubuntu and it says that there isn't PAE enabled. To be more specific, I'm running it on a Dell Latitide D600 and editing boot.ini through Windows XP SP3

Enabling PAE in the Windows bootloader won't affect Linux... unless I'm missing something? –  ChrisN Dec 25 '12 at 3:08

You enable PAE in Linux via the PAE kernel, or via BIOS, if such a setting exists. boot.ini route affects only Windows XP, not other OS running outside it.

If I recall correctly, modern 32 bit versions of ubuntu come with the PAE kernel by default. –  Journeyman Geek Dec 25 '12 at 7:20
    
@JourneymanGeek yeah, so do I, but mentioned it for sake of completeness –  Sathya Dec 25 '12 at 7:20
    
So, if lubuntu says PAE is not enabled, and its a newer version, its quite likely the system itself not having it enabled –  Journeyman Geek Dec 25 '12 at 7:22
    
Thanks for clearing that up. +1 –  user1610406 Dec 26 '12 at 22:03
