IBM PC330/PC350 - White screen or trap error switching from Win-OS/2 to OS/2
Applicable to: World-Wide
Problem :
IBM PC 300 Series 6577 and 6587 may exhibit an all or partially white screen or a Trap error when switching between a WIN-OS/2 session and the OS/2 WARP Desktop.
Problem Isolation Aids :
The following scenario is required to recreate the failing symptom:
1. Open the OS/2 System folder.
2. Open the Command Prompts folder.
3. Open an OS/2 or DOS Full Screen session.
4. Type "WIN" or "WINOS2" and press Enter.
5. Press ALT + ESC until the system hangs or traps.
If the system hangs, the display will be all or partially white and the cursor may be displayed as a large black box.
6. Press Ctrl-Alt-Del to recover the system.
The failure does not occur if the system is configured for VGA mode.
Solution :
The following changes must be made to the system configuration to eliminate this failure:
1. Obtain the latest S3 Trio64/64V+ video device drivers. (see below)
2. Update the DOS Full Screen video settings in the following manner:
a. Click the right mouse button over the DOS Full Screen session icon.
b. Click on Settings.
c. Click on Session
d. Click on DOS settings...
e. Click on DOS video settings, then OK.
f. Verify that:
VIDEO_8514A_XGA-IOTRAP = OFF
VIDEO_SWITCH_NOTIFICATION = ON
g. Click on Save. Exit, shutdown and reboot the system.
3. View the README file on the video device driver update diskette to determine if the users system requires the following command to be added to the AUTOEXEC.BAT file:
"COPY C:\WINDOWS\WINOS2.COM C:\WINDOWS\WIN.COM"
The AUTOEXEC.BAT file executes whenever WIN or WINOS2 is entered at an OS/2 or DOS Full screen command prompt.
NOTE - When starting a Windows session from a DOS command line, use the WINOS2 command rather than the WIN command.
