- BIOS means the video mode is set up using INT 10h to call the VGA BIOS
- VGA means the video card registers are changed directly bypassing the BIOS
- VESA means the video mode is set up using INT 10h to call the VESA BIOS EXTENSIONS
- BIOS and VGA modes are expected to always produce the same refresh rates, VESA modes can change the rate
