+          This instructs the driver to use EISA or PCI memory-mapped I/O
+          (MMIO) as appropriate instead of programmed I/O ports (PIO).
+          Enabling this gives an improvement in processing time in parts
+          of the driver, but it may cause problems with EISA (DEFEA)
+          adapters.  TURBOchannel does not have the concept of I/O ports,
