Summary:  On some machines, Highway 101 Setup will exit as soon as the initial blue screen is painted with the error "Overflow."  This incompatibility with certain machines is currently being researched. This error has been resolved as of Highway 101 version 3.03.  This technical note however provides a work around for this situation.

Details:
On some systems, when the display is set to 32-bit color mode, an overflow error to occurs on the initial setup screen update. To resolve this, drop the color depth on the end user's computer to 24-bit or lower color instead of 32-bit.  After installation is complete, the end user may increase the color depth back to 32-bit color without problems.

To change the color depth on most machines, perform the following steps:

1. Click on the  Menu

2. Click on the Settings Menu

Important: Many display drivers add their own custom tabs to the Display control panel application.  Be sure to ask the end user for the names of all the tabs that are displayed in this window.  If there is anything strange such as "ATI" or "MGA Settings", chances are, you will need to adjust color depth here.instead of the Settings Tabs.
 
7. Click the OK button to save your changes.  With most display drivers, you will need to reboot your system before you can continue.
