Detailed Description
Video mode: Framebuffer.
This beautiful structure contains everything required for using the graphic framebuffer in a very handy manner – however, it may not be well supported by current boot loaders... These information can be retrieved from VBE as well, though you then have to parse these huge structures containing a lot of useless stuff.
