Windows XP wont detect internet

Hello,
I just partitioned my Windows 7 HD, on my laptop, so i could dual boot XP Pro so i could run some old games and what not. Well i borrowed my friends XP CD and it installed Windows XP Pro Service Pack 3. Everything is genuine. Well i also have my desktop and i obviously have internet on this, but on my laptop with the XP it cant detect my internet connection and even when i have the Ethernet cable plugged in the orange light wont flash. So i just suspected its just drivers aren't installed that need to be, to run almost anything. So i need help figuring out how I can connect to the internet with my laptop to download any needed updates, or drivers or something. PLEASE help
