Analysis of information sources in references of the Wikipedia article "Physical Address Extension" in English language version.
Long-mode page translation requires the use of physical-address extensions (PAE). Before activating long mode, PAE must be enabled by setting CR4.PAE to 1. Activating long mode before enabling PAE causes a general-protection exception (#GP) to occur.
Execute Disable Protection is also enabled if supported by processor and if the kernel was compiled with PAE support; unfortunately, the feature is otherwise not available.
A 2-bit index consisting of PCD and PWT bits of the page table entry is used to select one of four PAT register fields when PAE (page address extensions) is enabled, or when the PDE doesn't describe a large page.

Supports up to 4 Gbytes of memory
To guarantee compatibility with non-PAE processors, the 32-bit versions of Linux Mint Debian come with a 486 kernel by default.

The non-PAE kernel will not be available in future Xubuntu releases.
