Unfortunately, I do not have another processor on the list.
I confirmed the PBA number.
Also I recorded the exact message displayed at startup.
It is as follows.

Update to the latest BIOS required to enable full functionality
and minimize erroneous system operation.
Press any key continue.
I am very happy if you give me advice.
Can you please provide us the current BIOS version that you are currently running? If it possible please provide us a picture of the BIOS screen.
With your advice, I was able to solve the problem.
First of all, there was a problem with the USB-PS2 converter I was using.
After replacing the USB keyboard, I was able to enter BIOS SETUP.
And updated BIOS using BIOS RECOVERY MODE.
As a result, it was possible to start normally without displaying a warning message.
Thank you for much advice!
