This board has two PCI buses; bus 0 is a 66MHz bus, and bus 1 is a 33MHz bus, so there is a PCI-PCI bridge (1011/0023) on bus 0. On bus 1, there is one ethernet device (1022:2000) and a PCI-ISA bridge (100b/0021). There is a problem allocating resources for the ethernet device, and I'm afraid I'm clueless at the moment. Can anybody give me an idea what might be going on?
