Can someone please tell me the difference between these two vmlinuz images ?
Difference between vmlinuz-2.6.32-34-generic and vmlinuz-2.6.32-34-generic-pae
linux;linux kernel;i386
The PAE kernel includes Physical Address Extension.  This increases the usable memory from 4 GB to 64 GB. The cost is that these kernels take up a little more memory and don't run on some old processors.
