Do you have 64M RAM on your machine, or is that what you told 3DS to use under
OS/2? If you have 64M on your machine, 3DS can't use it under OS/2 unless you
change your DOS setting for 3DS (increase the DPMI memory limit). The only
other explanation could be that OS/2 detected a DMA device that can't use
memory above 16Meg, so OS/2 is limiting memory access to the first 16M (all
memory above that is used by OS/2 internally). The OS20MEMU program (available
in the OS2SUPPORT forum) can tell you exactly how OS/2 is using your RAM.
