This software is a dynalink library that maps specified physical memory region to 32bit process address space and unmaps it. Before, all OS/2 32bit processes can access physical memory only via tightly-limited way such as DIVE/GRADD video framebuffer. This DLL internally issues mighty DevHlp_VMAlloc() to realize such memory mapping via common device driver SCREEN0x.SYS, thus, now you can access to any position of physical memory freely.
