VBE is made available through the Video Adapter's BIOS , which installs Interrupt vectors pointing at itself during system startup. Unfortunately, the older versions of VBE (those bundled with the vast majority of existing video boards) supported only a Real Mode interface, which couldn't be used without a significant performance penalty from within Protected Mode operating systems, such as Windows 95 or Linux . This meant that the VBE standard was almost never used for writing video-drivers, and each video board vendor had to invent a proprietary protocol for communicating with their own board(s).
