The process of downloading the MSI H170M-A PRO BIOS B.3 driver should begin automatically after a few seconds. If this does not occur, click on one of the links below (we recommend downloading the MSI H170M-A PRO BIOS B.3 driver from the primary server - this is the manufacturer’s Msi official website). If the download still fails to run, check whether your anti-virus software is not blocking the connection to the manufacturer server of the MSI H170M-A PRO BIOS B.3 diver.
