Dear Tobias Geiger,
Thank you again for replying to me.
If Radeon HD 6970 is guaranteed to work with Xen VGA Passthrough to
Windows 8 Consumer Preview, I may get it, maybe a few months down the
road. But it costs Singapore dollars $479!!!
I don't think I may be getting it SOON. My NVIDIA Geforce 8400 GS costs
only S$44 and I only bought it recently.
If I want to stick with Xen VGA Passthrough to Windows 8 Consumer
Preview with NVIDIA Geforce 8400 GS, then only Intel engineers Zhang
Xiantao, Ren Yongjie and Xen developers may be able to help me fix the
yellow exclamation mark glitch.
Seriously do you think there may be a problem with the MMIO BARs
pBAR:vBAR 1:1 matching? Is David Techer a software
engineer/programmer/developer? If not, how is he able to forward port
Intel's Xen VGA Passthrough patches from Xen 3.5-unstable (WHICH WORKED
100% SUCCESSFULLY) to Xen 4.2-unstable (which worked only PARTIALLY
successfully for MYSELF)?
Thank you again for proof-reading my Xen VGA Passthrough Version 1.6
documentation. If somebody is able to help me fix the glitch, there will
be a FINAL Version 1.7 documentation.

i can only say for sure that it works with a "Radeon HD 6970" - thats what i'm
using. stay away from dual-gpu cards, they have a more complex pci-bus
structure which may not work when passed-through.
The newer 7XXX may also work, i also think i read something about 5XXX cards
working - but don't take any older ones.
that said i can only tell for sure it works with the mentioned 6970 - simply
because i haven't tested any other cards yet myself.
regarding the patches - they should be the same, as he claims somewhere that
he took mine and forward-ported them to a then recent xen version.
With the ati card above you don't need any patches at all. none from david
techer, none from ati. pure vanilla xen (4.X or unstable) is enough.

Dear Tobias Geiger,
One final request from me: Can you check whether the Xen VGA Passthrough
patches hosted at David TECHER's official blog are the same as yours?
David Techer told me it's a NVIDIA driver issue, which I don't think so.
I seriously wonder what's wrong with the glitch. I am using NVIDIA
driver version 296.17 for Windows 8 Consumer Preview.
Xen VGA Passthrough to Windows 8 Consumer Preview: I can watch Youtube
videos with audio/sound and surf the internet as well. But I just can't
run 3d graphics benchmarks. Only 2d graphics benchmarks can be run.
By the way, I have only recently bought this Palit NVIDIA Geforce 8400
GS at SGD$44. If I buy an ATI card, what would you recommend that is
CHEAP? Must be PCI Express x16. Then do you think the Xen VGA
Passthrough patches are necessary any more?
Please refer to the computer hardware pricelist here
http://www.fuwell.com.sg/uploads/misc/Fuwell240312.pdf and recommend me
a cheap ATI card. Preferably SGD$50.
Finally, Xen VGA Passthrough to Windows XP Home Edition also has the
yellow exclamation mark glitch with NVIDIA Geforce 8400 GS. With Xen
Thank you very much.
sorry to hear that it didn't help.
Unfortunatly thats all the hints i'm able to give you - from now on
you're out there alone so to speak :)
Good luck - or (even on the danger of repeating myself:) just buy an ATI

Dear Tobias Geiger,
Thank you for reading through my Xen VGA Passthrough Version 1.6
I am now trying out your suggestion, i.e. expose the 4th memory range.
When I refer to David Techer's official blog and his emails, he only
mention the first 3 memory ranges. When I asked David Techer what
about the 4th memory range, he said nothing.
Let's hope I get lucky and get the yellow exclamation mark with NVIDIA
Geforce 8400 GS (ie Xen VGA Passthrough to Windows 8 Consumer Preview
*PARTIAL* success) FIXED.
By the way, what is the problem with my Xen WIKI? Xen.org
administrator Mr. Lars Kurth edited my Xen Wiki pages for me.
If it works, I will have Xen VGA Passthrough Version 1.7 documentation
and FINAL as well.
Thank you very much for reading through my documentation and giving me
suggestions. I hope it works now.
Dear Tobias Geiger,
I have just exposed the 4th memory region, patched dsdt.asl, recompiled
and reinstalled Xen 4.2-unstable but IT STILL DOESN'T WORK. There is
still a yellow exclamation mark besides NVIDIA Geforce 8400 GS in Xen
VGA Passthrough to Windows 8 Consumer Preview.
I still cannot run 3d graphics benchmarks. Only 2d graphics benchmarks
Please read through my Xen VGA Passthrough Version 1.6 documentation
again to see if there are any mistakes. Please. Please. Please. I want
to fix that glitch. Any more ideas?
I hope some expert engineers at Intel Corporation (Han Weidong, Zhang
Xiantao, and Ren Yongjie) can fix this glitch with Xen VGA Passthrough
to Windows 8 Consumer Preview. They are after all the original
authors/developers who wrote the Xen VGA Passthrough patches. But Han
Weidong has left Intel Corp, I think. He was still at Intel 3 years ago.
Thank you very much. Eagerly awaiting your reply.
