Obtaining a Usable Video Resolution

The system operates in VGA mode when the video display driver is not running to
accommodate all monitor types. VGA mode is used during initial installation of the video
display driver and when experiencing video problems. If you select a resolution that causes
the monitor to display incorrectly, do not press
operating system. Instead, use the Last Known Good option to return to the last known good
configuration recorded by Windows NT.
To use the Last Known Good option:
1. Restart the system.
2. Press the space bar at the following prompt:
Press space bar NOW to invoke the Last Known Good Menu
If using the Last Known Good option fails to correct the video display problems, you can
obtain a functional video resolution by restarting the system in VGA mode.
