I upgrade my system (using the built-in upgrade mechanism) from 9.10 to 10.04.

My kernel is reported now as 2.6.32-24-generic (that means 32 bit, right?)

The systems seems to only be able to access 3.2GB, whereas 4GB are installed.

I read these instructions on solving this on 9.10:
<https://help.ubuntu.com/community/EnablingPAE>

But it seems to imply the problem is already solved on 10.04 (which is not the case for me).

Is it safe to follow the instructions for 9.10 to enable PAE on my 10.04?

Thanks
