What is different between Linux kernel-pae, kernel-default, and vanilla kernel?
Think of it as being able to address lots and lots of memory … @!@
For application software which needs access to more than 4 GiB of RAM, some special mechanisms may be provided by the operating system in addition to the regular PAE support. On Microsoft Windows this mechanism is called Address Windowing Extensions, while on Unix-like systems a variety of techniques are used, such as using mmap() to map regions of a file into and out of the address space as needed.
