Hi,

Just download DJGPP and wrote a simple C program to dump some known memory
location.
The program compiled and ran fine. However, I noticed the contents of the
memory that I intend
to dump were not right. Later I figured out it must be the virtual memory of
the Windows, so, for
example, when I dumped the memory location 0x400, it's the virtual memory,
not the real physical
location 0x400 I want.

1, How can I program about the device's absolute address in DJGPP?
2. Can DJGPP compile 32-bit program so I can address the whole system
memory?

Thanks for your help in advance.
