Full-screen ultrafast video modes over-clocked by simple VESA routines and registers reprogramming under MS-DOS.
Fast full-screen presentation of stimuli is necessary in psychological research. Although Spitczok von Brisinski (1994) introduced a method that achieved ultrafast display by reprogramming the registers, he could not produce an acceptable full-screen display. In this report, the author introduces a new method combining VESA routine calling with registers reprogramming that can yield a display at 640 x 480 resolution, with a refresh rate of about 150 Hz.
