Similarly, how does Pae work? The point of PAE is to allow the kernel to address more than 4GB of physical RAM. In PAE mode, MMU tables map 32-bit virtual addresses to 40-bit physical addresses, with a three-level table (unlike non-PAE mode where the MMU tables map 32-bit virtual addresses to 32-bit physical addresses with a two-level table).
Secondly, what is PAE switch and why it is needed?
PAE (Physical Address Extension) switch is used to address more than 4 GB of physical memory, to enable PAE, you have to use the /PAE switch in the Boot. PAE switch to provide more physical memory to a program which reduces the need to swap memory of the page file and results in increased performance.
What is PAE kernel?
The Physical Address Extension (PAE) is a feature implemented in modern x86 processors. PAE extends memory addressing capabilities, allowing more than 4 GB of random access memory (RAM) to be used. NOTE: All the Linux machine with kernel version above 2.3. 23 supports PAE kernel.
