If the Extensions Manager is set to "Mac OS 8.5 All", or the set of extensions that loads at startup are otherwise customized, it is possible that an icon with a red "X" appears as the video driver extension(s) are loaded.

In Power Macintosh G3 (Blue and White) computers that ship with Mac OS 8.5.1, some of the ATI video driver extensions are part of the Mac OS 8.5 package, and some are part of the Power Macintosh G3 2.0 package. When selecting Mac OS 8.5 All, extensions that are not part of this set do not load, including the ATI Resource Manager extension. As a result, the ATI Graphics Accelerator do not load on the next restart and show an icon with the red X through it.

Before using the following workaround, create a duplicate Mac OS 8.5 set using the Duplicate button in the lower right corner of the window. This must be done because you cannot modify the default extension set. Name the set anything you like, then continue with the following steps.

1. In the Extensions Manager and choose View as Packages from the View menu.

2. Choose Mac OS 8.5 All from the Selected Set popup menu.

3. Check the checkbox next to the Power Macintosh G3 2.0 package to ensure all ATI extensions are enabled. (Make sure the checkbox has an "x" in it, not just a "-".)

4. Restart the computer.
