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 On 27/03/2012 19:08, Tobias Geiger wrote: > Dear Teo, > > i mean your problem is know, but no known solution exists. > That doesn't mean there is no solution, it just means nobody found one ye= t :) > > It's spoken/written out many places (xen-devel/xen-users) that VGA passth= rough > with nvidia works ok with windows xp, but not with windows versions higher > than xp. but it works with ati. > > to get to the actual problem: > you could try to also expose the "0xd30...- 0xd307fff" acpi regions. > no idea if that helps in any way i just saw that this is the only region > you're not mentioning in the patched dsdt.asl > > good luck - but please try to accept the fact that nobody _knows_ the sol= ution > to your problem (well at least nobody i know of). > > and about the pdf/wiki - ah... forget it > > Greetings > Tobias > > Am Dienstag, 27.
