IBM OS/2

4.In all modes, video corruption or out-of-sync screen is displayed when using Alt+Esc to switch between WIN-OS/2, OS/2, and DOS window and full-screen sessions started from the Startup folder. To avoid this situation, do not start ses- sions from the Startup folder or press Alt+Esc several times to restore.

5.Some programs, such as WINBENCH95, WINBENCH96, and After Dark 3.0, were written specifically for the Windows environment. In the Windows envi- ronment, these programs prevent any keystrokes from interfering with their proper execution. However, in the OS/2 environment, it is possible to switch context away from the Windows session without notifying these programs. General

Protection Faults (GPFs) may result. Therefore, context switching during the execution of WINBENCH95 and WINBENCH96 tests is not recommended. Also, context switching during the execution of the After Dark 3.0 demo is not recommended.

6.When attempting to start a WIN-OS/2 session from an OS/2 Full Screen session by typing "WIN" or "WINOS2" at the command prompt, it will not execute with the settings needed to support WIN-OS/2, and will result in video corruption and/or a system lockup. It is recommended that the user launch all Windows sessions via one of the WIN-OS/2 icons located in the "Command Prompts" folder within the "OS/2 System" icon.

7.When attempting to start a WIN-OS/2 session from a DOS Full screen or DOS Window by typing the "WIN" or WINOS2" command, the user must first be sure that the video settings of the session are changed to enable this feature. These settings can be changed using the following procedure:

a)Place mouse pointer over the DOS Full Screen icon (or any DOS session icon you want to alter). Press mouse button 2 (MB2), the right button, to bring up a context sensitive menu.

b)Place mouse pointer over "Setting" and press MB1. Next, place mouse pointer over the tab labeled "Session" and press MB1 again.

c)Use MB1 to chose the "DOS Setting" button.

d)Use MB1 to chose the "DOS video settings" option, and then click OK.

e)From the list of settings which appear ensure that

"VIDEO_8514A_XGA_IOTRAP" is switched OFF, AND "VIDEO_SWITCH_NOTIFICATION" is switched to ON, then "save" these settings using MB1.
