About VESAMTRR

  VESAMTRR is a tool to set a MTRR for VESA LFB to memory type 01 (WC).
  This may increase video memory write speed on DOS for P3s and P4s.
  In a Windows DOS box it is usually already done by the video driver.
  For more technical information please read the intel manuals.
  
  This tool requires cpu ring 0 access, so it cannot run on WinXP/2k/NT or
  DOSEMU, and it isn't needed there either.
  
  Thanks to RayeR for this hint!
