+// We convert the bios data structures before they are used.  They are read from bios,
+//   then each field is expanded into a 32 bit field into host byte order.
+//   Each data structure has a format string below that describes its packed
+//   layout in the rom.
+//
+// The format string looks like:
+//
+//    count defaults to 1
+//    item is one of
+//          b  (byte)
+//          w  2 byte word
+//          d  4 byte word
+//
+//  Eg: "1b3d"
+//
+//   means 1 byte field followed by 3 dword (32 bit) fields
