Passthrough onboard NIC IMMOU question

[steveBBB]

Hi there.

Just built a new unraid server with comet lake cpu and am trying to passthrough the onboard 1g NIC (board has 2.5 + 1) however its showing a PCH SMBus Controller and Comet Lake PCH SPI Controller in the same IMMOU group. (photo attached)

Will it effect anything if i pass the whole lot through to a VM? Ive tried downstream and multi-function without luck of splitting the group.

Note: It also had the onbaord audio in the same group but i disabled it in the bios as its not needed.

Appreciate any help.

 

Thanks

Pls try enable ACS in BIOS.

If that true, I think you can't separate most device in standalone group, seldom found that for onboard NIC.
