+/* Meaning of "bytelanes":
+
+   The card ROM may appear on any or all bytes of each long word in
+   NuBus memory.  The low 4 bits of the "map" value found in the
+   format block (at the top of the slot address space, as well as at
+   the top of the MacOS ROM) tells us which bytelanes, i.e. which byte
+   offsets within each longword, are valid.  Thus:
+
+   A map of 0x0f, as found in the MacOS ROM, means that all bytelanes
+   are valid.
+
+   A map of 0xf0 means that no bytelanes are valid (We pray that we
+   will never encounter this, but stranger things have happened)
+
+   A map of 0xe1 means that only the MSB of each long word is actually
+   part of the card ROM.  (We hope to never encounter NuBus on a
+   little-endian machine.  Again, stranger things have happened)
+
+   A map of 0x78 means that only the LSB of each long word is valid.
+
+   Etcetera, etcetera.  Hopefully this clears up some confusion over
+   what the following code actually does.  */
