Hi Yi,
Yes, upgrading your driver may help in this situation. Driver 2.7.1 was designed for use with DOS systems, and the latest version that supports the AT-GPIB/TNT card is version 1.7 (we started over on numbers a few years back). Here is a link to a table of GPIB hardware, operating system versions, and the latest driver that supports the various combinations.
