Though there is no memory optimizer provided with DR-DOS you
can still run MEMMAKER on DR-DOS (not recommended). While this
may give you some improvement, in most cases it will still be
sub-optimal. There is no better and more reliable way to fine-tune
a system than trial-and-error by editing the configuration files
itself (have a boot disk at hands!!! ;-).
Getting the most out of your system is a compromise between
memory usage, speed, and easyness, but ideally DR-DOS can
give you a maximum of ca. 720 Kb continuous conventional memory
(using MEMMAX +V on a MDA or Hercules card only), plus upper
memory (depends), plus 63 Kb HMA, plus extended memory above 1 Mb.
While a number of general rules of thumb can be given (like - very
basically - : loading everything high, shrinking unnecessary data
structures), memory optimization highly depends on the hardware
(which CPU and system architecture, which AddOn cards, etc.),
ROM-BIOS setup, and the drivers and TSRs to be loaded, and last
but not least the applications to be run. And it will always be
an iterative process.
It may take a while to study, but you will find tons of tips in
the backlogs (since 1997) of this and Caldera's DR-DOS/OpenDOS
mailing lists.
If you'd provide the necessary info on your hardware and post your
[D]CONFIG.SYS/AUTOEXEC.BAT/NET.CFG etc. files, we might be able to
guide you to much better point of start for your setup.
BTW, how much free memory do you have right now (MEM /A > mem.lst)?
