Hello JWell11,

 

Thank you for posting on the Intel Community.

 

The Intel® 80386EX processor that you mentioned is actually very old and since it was introduced in August 1994 and therefore is no longer under support. For these types of questions, we have different resources that might help you to find the information that you’re looking for.
