Installed This file was automatically installed as part of a recent update. If you are experiencing any issues, you can manually download and reinstall.X31 BIOS release notes:
Fixed BIOS flash part will be demaged after upgrade to A02 BIOS and CMOS battery power loss
[Root Cause] We do not check NvramLayoutChecksum in A02 BIOS. It causes CMOS data wrong if CMOS battery power lose.
[Solution] Check CMOS battery power status when system power on. If CMOS power lose, BIOS will load Failsafe Data(manufacturing defaults) to CMOS.
[Failure Symptom]
(1). Auto boot to setup.
(2). Shows "DQS training failed on previous boot, reverted to slower DRAM speed"
(3). After load setup default and reboot, system will prompt upgrade BIOS screen. Then BIOS will be erased and can't power on successfully again.
