I'll give that a shot.
Currently our images span IDE to SATA, including SSD. It works fine for all of the D series as well as the E6400, E6500, etc. But I believe they're based on the Core 2 Duo chipset where the newer systems are the i series. Not sure if that makes a difference or not.
The bios is currently set to ATA. I've tried the other options with the same results. I'll try removing all the drivers and start over. It's worth a shot and we can't afford to wait until we get the WDS server up and running.
Thanks for the advice.
