OmniBook 300/425 - Freeing up conventional memory

If disk compression is important, you could try using Stacker 3.xx instead of DoubleSpace. Stacker can utilize DPMS (DOS Protected Mode Services), so it can relocate and run most of its resident code in extended memory, so there should be more free conventional and upper memory for other applications to work with.
Stacker 3.12 and DPMS could be lifted from DR-DOS 7.02/7.03.
