No display after disabling CSM.

[afsar]

I am trying to enable reBar.But when i disable CSM (which is required for reBar) no display comes,no keyboard or mouse .After reseting bios it works fine again.my bios is UEFI,all drives are GPT.So my system supports reBar. I unplugged the gpu and booted from igpu.I disabled CSM and it worked fine.But right after i plugged in the gpu no display again.Currently I am using without reBar.

My Mobo:Gigabyte ds3h b550m
bios: f3d
CPU:Ryzen 5600g
GPU:ARC A750
This is a serious issue for me.
Plz help!

Hello afsar,

Thank you for posting in the Intel Communities, we would like to apologize for our delay in the response, but we are here to help you with the performance issue.

Based on the information provided, it is important to mention that we recommend letting you know that the Compatibility Support Module (CSM) or Legacy Mode must be disabled, and UEFI boot mode must be Enabled so the Intel Arc graphics can work. Intel has validated that the Intel Arc card should work with the CSM option disabled. However, we would like to ask for the following details:

• Are you able to enter the BIOS menu?
• Is there any other BIOS setting that you have changed?
• If CSM is enabled, does the Intel Arc graphics work as expected?
• What is the Intel Arc A750 graphics card model? (Limited edition, Sparkle, Gunnir, MSI, AsRock, Acer)

We noticed that another user is reporting the issue with similar specs as you in a different thread. So we would like you to take a look at the thread and if it is possible join the conversation to let you know.

Best regards
