There seems to be an issue with the mainboard’s bios, looks like it advertises rbar support but only provides 32bit resources. Please check the bios for the option “Above 4G decoding” and enable it. Furthermore, please make sure CSM is disabled.

Thanks for the pointer. “Above 4G decoding” was enabled by default and CSM was also disabled. after a reading a bit. I disabled the RBAR in the Bios setting. Now im getting the output.

I will address the RBAR issue later. For now I’m able to use my system.
Thanks a lot.
