- TITLE :Video Cards Using S3 Chip Set May Cause Hardware Conflicts
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- ----------------------------------------------------------------------
-
- Video cards that use the S3 chip set, such as the Diamond Stealth
- adapter, may cause hardware (I/O address) conflicts under Windows NT.
- Observed behavior may include general video problems and strange
- colors. Your computer may stop responding (hang).
-
- Some S3-based video adapters use an I/O address of 02E8 by default.
- This address is also used by default by most serial cards and modems
- as COM4. Other hardware, such as network adapters, may also use this
- address.
-
- To resolve any possible hardware conflicts, make sure all adapters in
- your computer do not use I/O address 02E8.
-
- NOTE: Windows NT does not support I/O address or Interrupt (IRQ)
- sharing.
-
- MORE INFORMATION
- ================
-
- By default, the Diamond Stealth comes configured to use IRQ2. This is
- the cascading IRQ to the second Intel 8259 Programmable Interrupt Chip
- (PIC). You may experience viedo problems, especially at higher
- resolutions, with this configuration.
-
- To correct this problem, you can disable the Stealth's use of IRQ2 by
- removing a jumper from the video card. Please refer to your
- Diamond Stealth user's guide for the procedure.
