The early quirks code only cares about the first south bridge, it's essentially just a chipset detect. So secondaries do not matter. > 2. some system with LinuxBIOS, could put first chain on bus 1 Do they or do they not? Please be specific. Anyways AntiLinuxBIOS doesn't have ACPI and early-quirks.c is 80%+ ACPI workarounds so they don't apply. The only exceptions are the VIA detect or the the HT broadcast workaround. I suppose both do not apply to these LB systems. -Andi -- ak@linux.intel.com
