Simply,
WinXP (and all NT-based) don't allow accessing entire physical memory
for DOS applications. It's memory protection policy which became more
restrictive since ages of Win9x. The same for win32 apps in user mode.
You will need to write some kernel mode driver that will access
physicam memory and transfer data from/to your program.
