Hello . I decided to update the graphics card in my laptop. No one has tried this on the laptop, so it predicts problems. The Toshiba Gt330m MXM-II card does not have a bios chip. What will be better. 1. Uploading a bios video into the system's bios , In this post, the user Filrond uploaded a video bios to the system's bios but in the Acer 5920G laptop http://forum.notebookreview.com/thr...ct-for-beginners.693102/page-12#post-10265054 2. Soldering a bios chip on the card , I borrowed the idea of soldering from the forum. http://forum.notebookreview.com/thr...5920g-soldering-project-for-beginners.693102/ I am asking for advice and help.
