A computer system includes a display control apparatus for preventing the display of certain characters during the bootup sequence prior to transfer of control to an operating system. The control may be instituted without significantly augmenting the basic input/output system memory requirements using a terminate and stay resident driver to cause certain interrupts which would otherwise result in screen displays to cache the screen display characters. The screen display characters maybe displayed upon user command if elected. The computer system is sensitive to a variety of conditions which require restoration of the screen display including situations which require user key input and the failure of the operating system to initiate within a certain period of time.
