Uh, hate to nitpick, but every use I've seen of the term "extended
memory" in my *life* has referred strictly to directly-addressable
memory above 1 MB (on '286 and higher).  

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?

Thanks in advance.
