The lower the DOS version the less memory it takes.  If you are very
tight on conventional memory, you can switch to DOS 2.1.  Most applications
will run on DOS 2.1 (but be sure to check the documentation first), and
you will save ~30k (that's just a rough estimate) of memory.
Also, if you own a VGA or 256K EGA, there is at least one shareware
program which will allow you to allocate 96K of the {E,V}GA's memory
to DOS for use as conventional memory.
Also, if you have the Chips & Technologies chipset, you may be able
to utilize "high" memory (memory above 640K) using a shareware
utility known as The Last Byte (available on simtel20).
Additionally, if you have a 386 or better, you can use Quarterdeck's
QEMM memory manager to load TSR's and device drivers into high memory.
