I tried to inject the inf using peimg, but that didn't work.
"The image directory specified is not a valid Windows PE image.
PEIMG failed to complete the operation with status code 0x8007000d."
What is the alternative? (forgive me if I am being dense, but I assumed this would be the same process) I am currently trying to do this for an XP image. I have yet to try it on my vista image.
