   Access EEprom/Bios of Nvidia Video Card
  HiI am new to this domain, I want to access Nvidia video card''s bios information(read/write) in my program.I don''t know the mechnism, can any one point me a direction? whereto look for? better give me some source code.ThanksHui 
  i''m not entirely sure on this one but you can''t typically write to a BIOS.  the usual mechanism for writing to BIOS is called flashing and it''s a really really bad thing to do unless you are flashing a new BIOS provided by the manufacturer.  if you''re flashing your own code you''re pretty much guaranteed to destroy the video card (at least until you reflash it with the manufacturer''s BIOS).  do you perhaps mean reading and writing to video memory?  if that''s the case check out either the openGL or DirextX APIs which provide functions for doing just that.-me
