The boards are shipping with different revisions and different BIOS versions, on the german forums a lot of people were getting rev1.2 boards with the v1.4 BIOS this past week.
The one I got 2 days ago was a rev1.2 with a v1.5 BIOS, others are getting rev1.1 BIOS. Officially none of these BIOS support Wolfdales you need BIOS 1.6, but I'm not looking for full Wolfdale support, I just wanna know if my BIOS can boot me into DOS so I can flash it, and according to the Anandtech link below there does seem to be some kind of support from v1.4 and upwards. The only way you'll know for sure is when you, or someone else, buys a Wolfdale and trys to boot it with a BIOS that is lower than v1.6
