MSI has a utility ( Live Update) just for what you are after. You may want to take the live monitor out of start up.
Download and open live update, you will need to allow an activex download to IE once the MSI page for this opens to check your bios and mobo drivers and video bios + video drivers.
Have been looking for a BIOS update for my 1.6 AMD Athlon XP 1900+ with MSI 6378 Motherboard. Have found the following and would appreciate any help determining if this is the right one. Am concerned about this as I have never done it before. Is this something I should do or should I let an expert do it? Any assistance will be greatly appreciated.
