DESCARGAR CONTROLADORES BOARD M810D

For the PCchips M810DLU I had to go to the Taiwan site and it lists a PCB version 7.5a, not the simplier 7.5, but I'm fairly certain that the video, lan, and audio drivers will be the pretty much the same. But I must add that trying to update the bios ( while it may be possible ) may also cause issues, so be careful and read all pertinent information before attempting any bios updates.

I e-mailed you the drivers let me know if it works
