Enable CSM support when using Integrated Graphics

testcy · May 15

I asked about this before, without finding solution, in BIOS if I try to enable CSM Support, it gets disabled automatically. If I disable Secure Boot first and then enable CSM Support, CSM Support again gets disabled. I just read that CSM often cannot be enabled if Integrated Graphics are being used. Do I need a discrete Graphics Card to successfully enable CSM Support?

What hardware? Why do you need CSM?

Also often you can only use CSM if it's required i.e. your boot drive is still using MBR. If GPT it'll often disable itself by default.

I can't enable CSM Support to boot from a MBR drive. The drive is visible in BIOS, but not listed as a boot drive. The system enters BIOS, instead of booting. I am thinking if the reason that CSM Support can't be enabled, is the use of Integrated Graphics.
