- Did you passthru all the PCI IDs or just one?
I passed the graphics, and the audio pci ids both to the hvm.
I also passed an usb card pci id.
- Was it primary or secondary graphics adapter?
It was the primary adapter. I tried the secondary as well, but could not
get it to work.
- Motherboard vendor/model and BIOS version/CPU version
Asus P7P55D-Evo
Bios 1307 (latest)
Core i7 860
- How did it work.. did you have some issues?
After i installed the catalyst driver, and XP rebooted, the graphics
login screen for XP appeared on the monitor (after some time).
I did not see any boot messages though...
