Folks,
Hope someone out there can help...
I’m helping a friend install an X299 dark. All was working well until we upgraded the BIOS from the shipped version (V1.04) to the current V1.09.
We updated the BIOS on the middle switch setting using the batch file from Windows 10.
No issues or power interruptions during the upgrade. When the system restarted, we were greeted by “CMOS Checksum error. Press F1 skip, F12 Enter Setup
Pressed F12, entered BIOS and saved it. System restarted and immediattly opened into the BIOS screen. Tried restarting several times with the same result.
Now we can’t get beyond BIOS. Tried to switch back to the V1.04 by switching the BIOS switch. When the system restarts, it goes to the BIOS screen of the older version. If I save and exit, system restarts and enters the BIOS screen.
I haven’t tried the CMOS Reset Button yet... wasn’t well documented on how to use it.
Thoughts/ideas?
