I'm going to give this another try and compile 4.2 from source with this patch http://www.davidgis.fr/download/xen-4.2_rev25240_gfx-passthrough-patchs.tar.bz2 but it needs my vga bios.

I'm stumped on how to extract that though. I see a lot of discussion lists mentioning nvtools, but I just can't find anything about what it is or how to use it. I found this site http://cgit.freedesktop.org/~lb/nvtools/ but it fails to compile.

Any help?

So people looking for those two boards and maybe others need to be careful about the bios version shipped.

What was it that they said exactly? I am curious because I have heard differing reports.

Thanks, I'll give it a try. But still how would I extract it myself if ever needed?

This is my card http://www.techpowerup.com/vgabios/index.php?page=1&architecture=NVIDIA&manufacturer=XFX&model=GTS+250&interface=PCI-E&memSize=512

as you can see there are 5 different bioses... I don't know how to find out which one is mine

After you update the BIOS with the 2.70 the VT-D not longer works

BTW , you do not need to update the BIOS if you do not have problems





ASRock America Support



Their English is pretty terrible. I asked why they removed support too, but they never answered that.

Get gpu-z and check your bios version there, you could also try to match the default clocks to the bios posted there, to extract it just unzip it, it should contain a .bin or .rom file, rename that to vgabios-pt.bin and put it on /tools/firmware/vgabios/vgabios-pt.bin

I managed to do it with nvflash. I compiled an older version for the yet-unstable 4.2 version because the patches are all very old. they date to almost a year ago.

Anyway, it compiled, but I couldn't get pciback to work, so still no deal...
post #496 of 779
I sugest you use xen-4.1.4 with xend, im using radeon cards atm but i managed to passthrough a nvidia card (9800gt) not so long ago with xen 4.1
post #497 of 779
BTW what distro are you using?
post #498 of 779
CentOS 6.3
post #499 of 779
If pciback is compiled as a module, you have to include it on the intramfs, if its not even built as module, you might have to rebuild your kernel, anyway, i recomend archlinux, its quite easy to create custom made packages for it.

I have arch for everyday use on my laptop, but for my dom0 I was aiming for a more stable distro. It was either CentOS or Debian
