Checking out the model, it is a 1.73Ghz Pentium M with 512Mb memory. Exactly how old is this model I have no idea but the memory is insufficient to run Vista at a good performance. The graphics is fine - ATI Mobility X700. I believe it is a 2005 model - pre-Vista era notebook.

What driver isn't available ? Chipset? Video? Audio? Video driver should be available. By the way, 512Mb RAM should be at least doubled to 1Gb (or best -> 2Gb).
