If it's a Pentium M, it does support NX (called XD for intel). If you find a workaround for that (a bios update may help), your bigger problem is going to be finding drivers for it. Your laptop is about as old as my inspiron 1501, and Windows 10 refuses to recognize the onboard graphics. It also doesn't have compatible wifi drivers. The generic driver works, but has to sit right next to the router.
