Its not just good, its the maximum you can get with MS-DOS. The remaining 3 kb are the interrupt table, the BDA and the IO.SYS stub.

This was detailed in Geoff Chapells "DOS Internals". I loved that book.

BTW for anyone interested, Geoff Chapells has a wonderful website dedicated to Microsoft OS internals. RIP Geoff.
