Thanks for your msg. I don't know if a diff version of Windows was installed because the laptop was a gift from my friend. I tried the link below. After going to Device Manager I selected and expanded IDE ATA/ATAPI. The expansion included:
Intel(R) 8280 1EB Ultra ATA Storage Controllers
Primary IDE Channel
Secondary IDE Channel
My CD/DVD drive was not in the expanded menu. When I expanded my CD/DVD drive I got Mats---a DVD-RAM UJ-811.
Thanks again for your help!!
