However I did manage to add the drivers to my old disk so I eventually figured it out. The key phrase in your solution is, 'as long as the Universal Network Boot Disk has the right drivers and can detect the nic card' which renders them useless to new machines. This is the correct way to do it however people have stopped making universal network boot disks which means that I had to add the drivers to the image of the old boot disk. I did this about 4 or 5 years ago, and I'm sure it will work today as long as the Universal Network Boot Disk has the right drivers and can detect the nic card. We only stopped using it when we started putting images on a USB drive that made the process much faster. The tech just had to boot to the cd, and once Ghost started all they had to do was choose the image from the mapped (X drive. I used a Universal Network Boot Disk and modified it to map to the image share, and start ghost(on the cd).

I made a disk(cd) a few years ago that did the same thing from a network drive.
