hello，last week，I had met the same problem when I passthrough the Gpu with 6100u. The video rom setting by the bios may affect the IGD passthrough. However we can not see this setting in the bios. So I change the bios version by contacting the manufacturer and it works. Sorry about my poor English，hope helpful to you.
