RE: How do you determine a 71B memory-mapped I/O device address?

I just read IDS Vol2 Chapter 4 and it seems pretty straightforward.
First it is written that the card reader MMIO is hard configured at address 2C000 to 2C01F.
Next, if I have understood correctly you must define a new chip that would respond to the configuration routine as MMIO instead of RAM or ROM.
Pages 4.1 to 4.6 gives a good explanation.
