PCI-to-Host bridge in ICH9 mode on VirtualBox
Posted: Sat Sep 17, 2016 6:44 pm
Does anyone know how to work with the pci-to-host bridge in ICH9 mode? I always read 0xFF... (from config address space) as if there is no device on the bus. ACPICA says that PCI bridge is present and provides a valid address is the same as in ICH9 datasheet. On my real hardware there are no such problems.
