I know that someone has tried it on the board DG45ID, D945GCLF2, DP45SG.
You will need to try to know this one. Uless someone else has already tried it.
Note: WHS has not been validated by Intel.
All the best,
I have been running WHS since the beta versions on my DG965WH desktop board with no problems at all! You might check out Homesevershow.com the guys are great and they just opened a forum section that
