Private shared memory on WinCE

Hi,

I have a quirky board on which I need my driver to allocated shared
memory (NdisMAllocateSharedMemory/NdisMFreeSharedMemory) out of a
certain predefined chunk of physical memory. The board runs WinCE 5.1. I
know that I can report a second region of RAM to the kernel using
OEMGetExtensionDRAM(). But I am not sure how I can configure WinCE to
use this region for shared memory allocation and force shared memory
allocation out of this region. Worst case I can manage
allocation/deallocation in this space myself but would be nice if WinCE
could do this for me. Any help much appreciated.

sincerely,
Vedvyas Shanbhogue
