// This driver supports a PRISM2 NIC 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.

// *** 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 PRISM2_MEMORY_MAPPED_OFFSET.
//
// In either mode, a seperate I/O pins is required for control of the NIC's
// hardware RESET line.
