The rules for defining a video attribute for a monochrome memory-mapped display are the same as those for PCDOS, with one important exception. Instead of using the physical attribute names for PCDOS, use the names listed in Table 46.4. The names for the memory-mapped physical attributes parallel the names used for PCDOS, but are prefixed with "MM" for memory-mapped. For example, MMNORMAL is the attribute name that corresponds to NORMAL.
