The process of downloading the ASRock H87 Pro4 BIOS 2.20 driver should begin automatically after a few seconds. If this does not occur, click on one of the links below (we recommend downloading the ASRock H87 Pro4 BIOS 2.20 driver from the primary server - this is the manufacturer’s Asrock 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 ASRock H87 Pro4 BIOS 2.20 diver.
