How i can build boost lib's for x86 platforms and plus Windows XP support using Intel Compiler 14? Also i have installed MSVC 2010/2013 on my PC
Boost it built by running bjam (or b2, they are the same). In your case you have to make sure you specify toolset=intel. For example,
c:\boost-dir> bootstrap.bat
c:\boost-dir> bjam install toolset=intel variant=debug link=static threading=multi runtime-link=static
