I am not sure. I would say not autocad but ones because with those I was not able setup settings for using them with batch override command in Project navigator.
I beleive these drives came from around the time of arcobat 6.
another thing i just noticed today with these were, when I tried to create a pdf, the entire image and line work did not should up on the pdf files but it did when i did a preview and it also did when i would send it to the printer, some weird error came out so fast I wasnt able to ready it
