Do you, by the above statement, mean to say that the first cut of SCO UNIX 3.2 would not utilize memory above 16 MB? What would happen in such a configuration -- would it be ignored? would it cause problems? In the new 2.0 release, how do you handle DMA between addresses above 16MB on an ISA bus machine?
