BIOS FLASH is attached on LPC. But the data in BIOS should eventually appear in the data bus of processor. How do the data in BIOS get to the data bus of processor? In the MSI ms9185, processor is connected with BCM 5780 via hyper transport, the BCM 5780 is then connected with BCM 5785 via hyper transport, and LPC is attached to BCM 5785. However, when the first instruction is fetched from BIOS, HT is not well initialized yet. How the data get to the data bus of processor?
