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.

Yours sincerely,
Mr. Teo En Ming (Zhang Enming)
