When PCI base address register set 0x1000(I/O space), inb(0x1000) reads wrong value (tulip net driver reads wrong eeprom data). When PCI base address register set 0x10001000(I/O space), inb(0x1000) reads valid value. PCI I/O address and CPU bus address seem to have to be same. > > If PCI IO address was 0, io_offset should be 0. Otherwise, io_offset > should be -0x10000000, as current code does. Based on the above result, io_offset should be -0x10000000. > So if it does not work now, something's going wrong... but I have no > idea now. Yoichi
