Go to the Toshiba website and download the
drivers from there. Follow the link below, click on
Download, select your model according to the dropdown boxes (self explanatory) and then click the red
GO button. If not pre-selected, click on the
Downloads tab and then refine your search (OS, download type/category) as necessary. Your available downloads will be displayed. It is then just a matter of downloading them and then burning them to a CD/DVD (or even putting them on a USB drive).
