I flashed to F5h....there are new strap options and additional info.

They added a 4" strap..it's not a typo. They have added some info about an 800/1066/1333 strap setting.

+ = 1333, " = 1066, and one for 800...seems they are preping the way for the new 1333FSB processors, i'm sure these bios will go to final soon.

I didn't see any other changes or adiditions, F5h is dated June 28th 2007.
