[stuff deleted] While I'm fuzzy on the details (it's been a while), there IS a conflict between COM4 and certain Diamond video boards. Those boards used extended I/O port addressing, and several port addresses on the board ended with 0x2E8, which conflicts with the standard COM4 I/O address. If you take a look at the Diamond manual, it lists the I/O port addresses used by the video board. -- Mike Loewen Center for Academic Computing Email: mcl8@psu.edu The Pennsylvania State University Phone: (814) 863-4356 University Park, PA 16802 Office: 17 Willard Bldg. http://ripsaw.cac.psu.edu/mloewen.html
