ABSTRACT:
The present invention relates to software used in conjunction with the BIOS POST process to preserve certain messages (referred to as "safeguarded messages") displayed on a video screen, while other messages, which are considered disposable messages, are not preserved on the screen. In one embodiment, prior to displaying a message, the software determines whether the generated message is a safeguarded message. The software then displays safeguarded messages and disposable messages on the video screen on preselected lines assigned to each category. Once the video screen is full of disposable messages and an additional message is to be displayed, a disposable message is removed from the screen leaving a character display line empty. The additional message is displayed on the newly-empty character display line. During the removal of a disposable message and the displaying of the additional message, the safeguarded messages are preserved on the screen.
