Hae reformated a Toshiba L350-170 laptop and all was working fine but SB Contollers drovers were missing. Found chipset XP drivers on the Tosh website and downloaded and installed as directed on screen. It asked me to reboot, which I did but now I cant get beyond the first page that offers Press F2 to get to setup. Pressing F2 does nothing, it stays locked on the page. Any ideas?
