Drivers For Windows Xp 32bit For Dell N5010?

i have bought a Dell laptop about a month ago with windows 7 home basic 64 bit OS,320 GB hard disc and i3 processor. I want to install xp-home-32-bit as second OS.My problem is: Where to get drivers for xp 32 bit. Searching on Dell site i found out they have drivers for windows 7 and vista 64 bits only for my model.I am all ready for installation of xp except above issues. (i.e. i have all necessary softwares like nLite,EasyBCD,netframework etc.) won't my win 7 64 bit drivers work on xp 32 bit ?tell me exactly which drivers are needed ? And where the make and version of each can be found on my laptop(Dell Inspiron 15R (N5010)) ?
