I hope this is an easy question for someone out there! I have an old Cannon laptop that has a corrupt Windows 95 file so it won't boot up. It also doesn't recognize its CD drive, so I can't get the computer to boot from the D drive. I don't know how to get to the BIOS on this old guy to try to get it to see its CD drive. I can get to a DOS prompt, but my DOS memory is getting pretty dim. Any suggestions?
