Missing CDROM Drive

I created a windows 95 boot disk and formatted the C: Drive. When I rebooted, I had lost contact with the CDROM Drive. After opening the case and discovering the CDROM drive model (CD620E) I found the appropriate driver on teh web and installed ( itsaid it installed correctly). Yet, when I rebooted I still couldn’t access the CDROM drive ( D:). Any thoughts about how to get around this as I need to reload Windows and only have it on disc.

Thanks,
