DOCUMENT:Q102923 26-OCT-1999 [win95x] TITLE :STB WIND/X Video Card Interferes with COM4 Serial Port PRODUCT :Microsoft Windows 95.x Retail Product PROD/VER:WINDOWS:3.1,3.11 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows versions 3.1, 3.11 ------------------------------------------------------------------------------- SUMMARY ======= According to STB Systems, Inc., the STB WIND/X video card may conflict with the address of the COM4 serial port (2E8h). This article contains an excerpt from the "WIND/X Video Card" user's manual that describes the problem and workarounds. MORE INFORMATION ================ The following text is from page 1-4 of the STB "WIND/X Video Card" user's manual: The WIND/X graphics controller chip uses the hex port address 46E8 for one of its extended register sets. When only the first 8 bits of this 16 bit address are decoded in any operation, the address appears as hex port address 2E8, which is a popular hex port address for a COM 4 serial port. This may result in an address conflict and prevent COM 4 from functioning or cause it to operate in an unpredictable manner. (e.g., Windows losing text, COM 4 locking up) If you have a COM 4, or any other device in your system that you suspect uses the 2E8h address, consult the device documentation for alternate address selection/configuration. For more information about the WIND/X video card, contact STB Systems.
