ASUS Motherboards Microcode Update for Speculative Execution and Indirect Branch Prediction Side Channel Analysis Method
Important Information about Meltdown and Spectre
ASUS is aware that current Intel® and AMD microcode versions might be subject to recently identified security vulnerabilities, commonly known as Meltdown and Spectre. We are working diligently to update ASUS motherboards that support 6th, 7th or 8th Generation Intel Core™ processors or Intel Core X-Series processors for X99 and X299 platforms*, and also all AMD AM4 / TR4 processors for X399 / X470 / X370 / B350 / A320 platforms. We recommend customers update their systems by downloading and applying the latest BIOS, as soon as the relevant revision becomes available. We also encourage customers to review relevant security information from Intel and AMD, paying particular attention to the appropriate identification and mitigation measures.

Did reverting work? I happened to learn a lot about that error due to some non-firmware related reasons...I'd be surprised if that was the cause of the error. In my case it was because I had trouble getting the RAID drivers installed before switching to RAID mode. I upgraded from 0902 to 1003 without any issues.
