I have a sony vaio PCG-7Z2L. I recently decided I wanted to get rid of vista and install XP, but in my haste I deleted everything on my hard drive. In order to install XP I need to install drivers but I dont know what chipset I have and I cant run the programs mentioned in other threads because my hard drive is completely blank. How can I find out what chipset I have? Any help is greatly appreciated. Thanks.
