That might be a problem. > I can't tell that v2 ever sets it. In the 8111 datasheet it looks like that bit makes it so that bits 8 & 9 of the address get ignored so that only 256B of every 1024 are accessible. I don't think that's what we want. Looking for that I found an interesting couple of defines. include/device/pci_def.h:#define PCI_BRIDGE_CTL_NO_ISA 0x04 /* Disable bridging of ISA ports */ include/device/pci_def.h:#define PCI_CB_BRIDGE_CTL_ISA 0x04 I can see that they're used in two different places (one for the hardware, one for the device struct), but it still seems confusing. Thanks, Myles
