How do i get into my (Win95) OS, Pt 2

Hi F1.The cdrom and hdd are plugged into their original slots on the motherboard. I looked for something near the slots to help me differentiate between the primary and secondary slots, but can’t tell. However, i had changed the jumper switch on thecdrom from its’ original position (slave) to master, and to cs (cable select). I have since changed it back to slave, but to no avail. I’ve tried the previous solutions offered by diskaus and soulrider, but it’s still not letting me into the OS. I’mthinking about sending the hard drive out for data retrieval. What do you guys think?
