The last Pc fair, almost every booth has put up printed notifications of such notebooks. Especially those from HP. I did not know Acer would also face this problem.

Anyway if your notebook is supposedly preinstalled with Winxp Home, there should be a windows OEM sticker with serial number on the back. Borrowing a XP home OEM CD from your friends or copy one from your friendly PC shop would solve your problem. The drivers you could just download from acer website.
