 Ergo driver for the SNI Notebook PCD-4ND
____________________________________________

Functionality: This driver sets the screen refresh frequency
               to higher values then set by the supplied DOS and windows
               drivers.

               The driver is active ONLY if you work with an external
               monitor. You can not switch back to the LCD panel if
               you have loaded this driver.
               Higher refresh rates are not possible and not
               needed with the LCD panel.
               The Refresh rate setting of this driver overwrites under windows
               the setting done by the drivers of the VGA supplier.

Important:     Not all the monitors support higher refresh rates
               please consult your Monitor supplier and your monitor
               reference manual to find out what is the highest
               refresh rate possible.

               warning: driving a monitor with a refresh rate beyond
                        it's specification can harm the monitor !!
