I was wondering about this myself. I never really noticed since v0907 experience. But for me it is the 5th & 6th block to the end and it shows not hashed at each BIOS flash from then on and verifies the same. And now when I try to load previously CMOS profile saves (that belong to given BIOS version) I get the error message the cannot load BIOS ROM, boot block corrupted or not compatable. What's up with that. None of them work anymore for other BIOS versions either.
well i dont get any of that but then i dont try to load up old profiles, i just redo my settings. only one time did the little lcd screen show CMOS error and then it booted up fine and has worked since. must be something that 0907 does, leave one square at the end of the flash hatched (or not filled in) who knows, i might call asus tech and be like wtf, so far board is still doing fine, i like it a lot

also, this is weird, when i installed this second board into my case (cm stacker original) and the pci slots lined up with the case brackets. believe it or not my first board had slots that did NOT line up, and my cards barely fit. I installed the board the same way as the original (theres really only one way to put it in) and i was like wow my video card can fit into both the pci express slots now. very odd, never seen this problem before.

and if you guys close this thread, just open a new one because i like reading it to see how people are doing with the board
