// Direct I/O mode assumes the NIC address, data, and control lines are
// connected directly to processor I/O pins.  The memory-bus accesses are
// software emulated.

// Memory-mapped mode assumes that the NIC is connected the processor via
// the external memory bus, and that the NIC address space starts at the

// In either mode, a seperate I/O pins is required for control of the NIC's
// hardware RESET line.
