ASRock is aware that the current Intel^® microcode version might be defected by security vulnerabilities. And there's a reboot issue identified on the microcode released earlier. (Intel's official announcement, please refer to : https://newsroom.intel.com/news/root-cause-of-reboot-issue-identified-updated-guidance-for-customers-and-partners/ )

To fix the security vulnerability (SA-00088), ASRock is committed to work closely with Intel to develop and update new BIOS for our 8/9/100/200/Z370/X99/X299 motherboard series. We recommend users update their systems by flashing the latest BIOS once the revision microcode is released from Intel. To mitigate this issue promptly and constructively, please refer to below links for more info and stayed tuned.
