// This driver supports a CS8900 connected in memory-mapped or direct I/O mode.
//
#define GENERAL_IO 0
// 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.
//
//#define MEMORY_MAPPED 1 (*** MEMORY-MAPPED NOT YET IMPLEMENTED ***)
// 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
// memory location CS8900_MEMORY_MAPPED_OFFSET.
//
// In either mode, a seperate I/O pins is required for control of the NIC's
// hardware RESET line.
