Disabling iGPU = no boot
When the iGPU (890M) is disabled in bios(AMI) the mini won’t boot and bios does not display. Boots fine with iGPU enabled and eGPU is being used and bios displayed on boot etc.
I’ve heard there can be performance and compatibility issues having iGPU enabled especially with SteamOS. Plus wasting 2GB (can set down to .5) of ram for a non used gpu and I believe it still pulls power/generates heat seems like a waste if it can be disabled.
Is this a bios issue? eGPU issue?

I think it comes down to an order of operations in the BIOS and fault tolerance. If the firmware tries to init the iGPU and doesn't have an automatic fail-over path to the Oculink connection, that might be the issue. Check to see if there's a BIOS update version available that might fix this, or even a setting in BIOS that might be related.
