H A Duvesafb.rst2 uvesafb - A Generic Driver for VBE2+ compliant video cards
8 uvesafb should work with any video card that has a Video BIOS compliant
12 v86d. v86d is used to run the x86 Video BIOS code in a simulated and
32 uvesafb is a _generic_ driver which supports a wide variety of video
33 cards, but which is ultimately limited by the Video BIOS interface.
37 - A strict and limited set of supported video modes. Often the native

40 video mode you want to use. This can be especially painful with
41 widescreen panels, where native video modes don't have the 4:3 aspect
44 Video BIOS. Note that many nVidia Video BIOS-es claim to be VBE 3.0
