Although most modern systems typically use device drivers that directly set the video mode, it is not feasible for hobbyist systems to have a device driver for every video card - a problem that also plagues older, unsupported systems such as Windows The command register is available through port 43h. Such systems instead can drop into Real mode to switch the video mode, then draw to the framebuffer directly.
