What Is a Video BIOS?

That is, the video BIOS or the graphics card BIOS is mainly used to store the control program between the display chip and the driver. In addition, it also stores information such as the model, specifications, manufacturer, and delivery time of the display card. When the computer is turned on, this information is fed back to the screen by displaying a control program in the BIOS. In the early days, the display BIOS was solidified in ROM and cannot be modified, but most display cards now use large-capacity EPROM, the so-called Flash BIOS, which can be rewritten or upgraded by a special program.
