Re: Dear Tobias Geiger, I Need Help with Xen VGA Passthrough to Windows 8 Consumer Preview / XP (Xen 4.2-unstable)

["Teo En Ming (Zhang Enming)" <singapore.mr.teo.en.ming@gmail.com>]

Dear Tobias Geiger,

Thank you for reading through my Xen VGA Passthrough Version 1.6 
documentation.

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.

Yours sincerely,

Mr. Teo En Ming (Zhang Enming)
Singapore
