You'll need a 95 startup disk to get you to a command prompt. Before that, be sure your CMOS is set to "boot to floppy." From there (if you remember DOS well enough) you'll need to look around for the .cab files. You're hoping for a setup.exe file in that folder, and not just the .cab's. Since you're running 95, maybe you can find DOSSHELL. At least it will be some sort of gui. You can get a decent list of DOS commands from a multitude of websites.
