Hi Christopher,
I’m somewhat surprised that you have installed Vista as most people are desperate to go the other way...
Most Win 7 drivers will work with Vista but XP drivers will not.
I assume that you are unable to access the web at present on the VPCF13L8E and need to download from another machine and then transfer to the VPCF13L8E? If your CD/DVD drive is working then download the drivers on another machine and burn them to CD.
Alternatively if your recovery partition is intact then you could revert to factory settings, download the required drivers, burn them to CD and then re-install Vista. To access the hard drive recovery utility tap F10 at boot.
Most of the available Win7 drivers available are 64Bit so fingers crossed that you have installed Vista 64Bit.
