Where does the extra come from?
On much of my hardware, the most I can assume is 128 bytes - subtracting many bytes that are weirdly hardware controlled (such as date). Some of our hardware has 256 bytes. The io ports only support an 8-bit address I thought? That said, if newer parts really do have so much data, that is great news. ron -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
