Open the mobo, and locate all FLASH chips. If one of them is a 82802AB or 82802AC, then you *MIGHT* have an Intel FWH with a HRNG (some of the FWHs have their RNGs disabled, and since Intel stopped guaranteeing the RNG is there, they would install one such FWH in their boards just the same). If none are a 82802AB or 82802AC, you don't have an Intel FWH with a HRNG. Even if you had an Intel board that is known to sometimes have an Intel FWH with an RNG, like the D875PBZ, that wouldn't mean much. They could have used an non-Intel equivalent part for that production run, for unknown reasons. You really have to check. -- "One disk to rule them all, One disk to find them.
