IBM ValuePoint - Monitor failure with S3 video
Applicable to: World-Wide
Symptom:
Any multi-scanning monitor (Multi-Sync), which includes the PS/ValuePoint 6314, 6317, and 6319, may blank out when changing video modes. For example; when entering or exiting a text mode application, and switching to a high-resolution graphics application. When this "blanking" occurs, the user should power the monitor off/on to recover. In some cases the monitor may not recover.
Problem Isolation Aids:
If this symptom is experienced, verify the monitor is being driven by a PS/ValuePoint 6382/S, 6384/D, or 6387/T system that is using the S3 Video Drivers that accompanied the system. If so, this tip applies.
A problem has been identified whereby the above configuration may - during MODE switching - present Horizontal Synch signals from the system unit to the monitor that are out of normal frequency range/duration. Multi-Sync monitors will attempt to lock onto this spurious frequency and potentially blank out. Mode switching occurs when running an application and the user changes from one task window to another, such as changing from the OS/2 desktop to a WIN-OS/2 session.
Fix:
Note:
The failure modes for video and monitor devices can occur for reasons other than those described above. Utilize the following steps to eliminate the above failure symptom as a possible cause:
The complete fix is dependent upon which operating system is installed:
1. For DOS-based system operations, obtain and install the latest PS/ValuePoint Flash BIOS update. No additional changes or updates are required.
2. For OS/2-based system operations, obtain and install the latest PS/ValuePoint Flash BIOS update. In addition to the Flash BIOS system update, you MUST obtain and install the OS/2 S3 Driver Update package "S3-16M.DSK" with a file date of 5/2/94.
The ValuePoint Flash BIOS update and the OS/2 S3 Device Driver Update Packages may be downloaded by Double-Clicking on the appropriate Icon :-
