Please check and make sure these match to your motherboard. If not, there are a couple of different bios' that may match at


I have found the MB520N to match to your bios id string 51-1700-008045-00111111-071595-i430vx-h.

I'm not responsible for any damage that may occur from the bios upgrade. You should always verify your motherboard and bios match up before performing any upgrade.
