Hey
I am using an ASRock Rack EP2C612 WS with Dual Xeon.

TLDR; After BIOS update, I cannot enter the BIOS setup. PC freezes at the ASRock logo. However, booting to Windows works.

I performed a BIOS update from 1.30 to 2.10 (USB flash). It was successful. PC started to the OS.
If I press Del or F2 key when the ASRock logo is coming up, it beeps once and freezes (does nothing).
The ASRock logo will still be displayed, but no BIOS setup will be visible. I waited for several hours, but its not entering bios setup. The debug display shows state b6.

What still works:
Access to boot priority menu (F11) and flash menu (F6)

What I have tried so far:
- Unplug the power cable for 10 minutes
- Removed the CMOS Battery (combined with power cable unplug)
- Used a new CMOS battery
- Use only one RAM in A1 slot.
- Used a different RAM in A1 position (but only from the same system, since I do not have DDR4 RAM from a different system)
- Made a RAM test (Memtest86: All Tests have 0 Errors)
- Removed the graphics card
- Removed all drives
- Trying to flashback to 1.30 (but the prompt says that it is not possible to go under 2.0)
- Flashed to 2.20 -> Windows is booting but no setup entering. Stopped at code b6.

Why I did the Bios update:
I had some crashes / freezes last two years. Range varies between some hours or days or even weeks with no crash. The error occurs with no scheme. But lately, it got intensified (multiple times a day). Then I read about the stability fixes in the Bios changelog and updated it.

System specs:
MB: ASRock Rack EP2C612 WS
CPU: Intel Xeon E5-2683 v3 (Dual)
RAM: 4x Corsair DIMM 16GB DDR4-2133
Graphics: NVIDIA GA102-300
PSU: BeQuiet Z1-1000
OS: Windows 10 Build 19042.804 (20H2) / Ubuntu 20.04 LTS

I would be happy about any advice / tip.
