Almost right, but you forgot something.

In your data declarations, if you do not specifically specify the
keyword far, then the declaration is left in the default data
segment, which can be a problem if you have more than 64k of global
data. Granted, DS is referenced by a far pointer, but you are still
limited to 64k per data segment, eventhough you can reference upto
1 megabyte of data and 1 meg of code. This is because the far
pointers in the LARGE model are not normalized 32 bit, but
segment:offset 20 bit pointers.
