Dear David Techer, I always read my emails very carefully. But in Xen VGA Passthrough to Windows 8 Consumer Preview, Device Manager reports that "Windows has stopped this device because it has reported problems. (Code 43)" for NVIDIA Geforce 8400 GS. Device Manager also reports that "This device isn't using any resources because it has a problem.". Yellow exclamation mark for NVIDIA Geforce 8400 GS Xen VGA Passthrough to Windows 8 Consumer Preview is NOT the issue. *_I believe the problem has to do with VGA Card MMIO BARs 1:1 matching, i.e. the file tools/firmware/hvmloader/acpi/dsdt.asl._* _* David Techer and Intel Corporation engineers Zhang Xiantao, Ren Yongjie and Han Weidong and Citrix Engineer Ian Campbell:*_ Could you help me to check through Sections 3, 4, and 6 of my "Xen VGA Passthrough - Version 1.6.pdf" documentation to see if there are any mistakes? Please also see the following Xen VGA Passthrough to Windows 8 Consumer Preview screenshots for Device Manager.
