Been there done that.   I have an image at work that will work on a variety of computers.  The tech who originally made no longer works for the company.  for the life of me I can not remember how he made it.  I "think" when he originally made it he hit f5 to make it non-hardware related, then built the image, then he copied a few .sys files into the C:\WINDOWS\system32\drivers folder and ran a .reg file he created and then ghosted it.  Now I have an image I use for any machine we have.  Compaq, HP, Dell, workstations or laptops.  I just didnt want to drive to work to pull the image off of our network.  I was hoping there was a guide somewhere. Again, I hope it makes sense Thanks
