- A compromise is QEMM386 or something like that. Microsoft's EMM386
- doesn't use get the most out of your expanded memory. For instance,
- EMM386 sets aside some expanded memory for use as simulated expanded
- memory. Quarterdeck's QEMM386 doesn't do that - unused memory is
- simultaneously available as either extended or expanded memory,
- whatever your software is looking for. It's also easier to use for
- efficient high-loading of resident software.

- True. There's no way to get around that limitation, but there are
- better ways than Microsoft's to do the best you can within it.
-
- I use DESQview/386 (which includes QEMM386 and DESQview on my 4 MB
- 386SX. It gives me reasonably good memory management as well as
- multitasking of DOS applications. With a 16 MB 486, you can run a
- multitasking OS (instead of a multitasking executive within a
- single-tasking OS), but you might make your system slower.
