[Motherboard] When I use the integrated graphics card on the Intel® 500 series motherboard , why does the CSM option under BIOS appear gray and non-configurable?

Solution and explanation:

Please use a graphics card that supports VBIOS, then the CSM option can be selected.

Recommended graphics card series: NVIDIA: GTX 1000 series or above; AMD: RX5000 series or above

Note: 

Not suitable for desktop computers.

Intel 500 and the latest series of chipsets do not support VBIOS display, so the integrated display does not support legacy boot, use a graphics card that supports VBIOS to enable CSM.

It can be distinguished according to CPU and Chipset, refer to the following

Q&A:

Q1: What is the function of CSM?

A1: CSM, full name Compatibility Support Module, is an item in Boot in BIOS, CSM can also support UEFI boot.

If you need to start the traditional MBR, such as installing Windows 7, you need to enable CSM. When CSM is disabled, it becomes pure UEFI boot and fully supports Secure Boot.
