You write ffffffff to a register. it reads back as the moving bits + non moving bits. But at that point, until you change it, that's also the address it will decode. In this case, sadly, we set a bar to ffffffff, to set its size, and it reads back ff000000, which gives us moving and non moving. Oh but ... it also decodes that address, top 16m of addrss space, -> no more ROM. hardware does this? yeah, probably. ron -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
