After I got bootstrap message `Ross(?)', I cannot use PCI bus. >How-To-Repeat: >Fix: It seems that reading from 0x45 has no meaning on my machine. Without following patch, my machine reports like this. pcib255: <Ross (?) host to PCI bridge> on motherboard And no other PCI devices are found, cannot mount root device, then panic. It seems that pci_cfgread() returns 0xff. PC9821RvII uses Champion as it's chip set. Champion is product of Reliance Computer, I beleive. So, I feel strange about message `Ross(?)'. `RCC' is more precise?
