Manually Removing incorrect drivers (Prolific) (Originaly Posted on 23-APR-2003, by Robert L. McConn) (Original Thread: Stop Errow Screen with win XP ) I had the same problem and had no luck contacting SilverLeaf. They tried their best but could not solve the problem. The Bafo web site shows a new BF810 driver Version 1.5 for Windows XP. However, when I download this zipped file, I still got a driver SER2PL.sys Version 1.3.0.0. I then contacted Bafo and they sent me an e-mail with the prober driver attached. They also included detailed instructions on removing the old version 1.3. Properly removing the old driver is very important. Here is Bafo's response and attached to this reply is the proper driver. Hope this all comes through o.k. If not feel free to contact me by e-mail and I will forward it all to you.
