The i810 era Intel RNG is in the FWH (the firmware hub, aka BIOS FLASH chip). You can have it anywhere someone uses an original Intel 82802AB or 82802AC FWH, no matter the chipset (the FWH is a LPC device). But you have to be lucky enough to get a Intel FWH, and one that has the RNG inside working. I doubt Intel is producing them anymore, but you could ask them. The last board I know of that had those *if you were lucky* was the D875PBZ. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
