Virtual Memory Problem

Hi there!
This is my problem: I am working on a 3.5" motherboard equipped with NS Geode Gx1-300Mhz processor and CS5530 chipset and 128 MB RAM; I’m using Qnx Momentics 6.2.0;I tried to use malloc() requiring more bytes than 128MB but it fails.I tried malloc() on the same system using Windows 95 and it worked.
Is there something I have to do to enable virtual memory in Qnx?

It’s not supported.
