Dear All,

Hypervisor: Xen 4.0.2-rc1-pre
pv-ops dom0 kernel: 2.6.32.26
Distro: Fedora 11 Linux x86_64
Graphics card: NVIDIA Geforce 8400 GS PCI Express x16
Motherboard: Intel Desktop Board DQ45CB

I have applied patches from Tobias Geiger's xen-devel mailing list 
thread 
(http://lists.xensource.com/archives/html/xen-devel/2010-05/msg00441.html) 
to Xen 4.0.2-rc1-pre. VGA Passthrough to Windows 7 Enterprise 90-day 
Trial is *partially* successful only. As for Windows XP Home Edition, it 
boots up with a garbage screen and just hangs there.

I have attached 2 screenshots showing the error pertaining to NVIDIA 
Geforce 8400 GS in Device Manager in Windows 7 Enterprise.

The Device Manager dialog box reports that "Windows has stopped this 
device because it has reported problems. (Code 43)" and also "This 
device isn't using any resources because it has a problem." Please refer 
to attached screenshots.

I have made modifications to the patch file 03_dsdt so that it is 
compatible with my secondary graphics card. Please refer to attached 
patch 03_dsdt.txt.

I am unable to apply the patches from Tobias Geiger's xen-devel mailing 
list thread to Xen 4.1-unstable because pass-through.c reports an error 
during compilation (make tools).

Please advise accordingly.

Thank you very much for your kind attention.
