How can I access all bytes of RAM and ROM of my computer?

Question

I tried pointers and reference(&) but when I try to get the info(I am only reading from memory) computer \"beeps\" and program terminates. NO problem when assigning a pointe

Answer 1

This should help me:

typedef struct _MEMORY_BASIC_INFORMATION {
PVOID BaseAddress;
PVOID AllocationBase;
DWORD AllocationProtect;
DWORD RegionSize;
DWORD State;
DWORD Protect;
DWORD Type;
} MEMORY_BASIC_INFORMATION, *PMEMORY_BASIC_INFORMATION;

and this:

VirtualQueryEx(
HANDLE hProcess,
LPCVOID lpAddress,
PMEMORY_BASIC_INFORMATION lpBuffer,
DWORD dwLength
);

at least in my OS thanks Bo Persson and Jerry Coffin or Mysticial

Answer 2

You can't. Modern OSes use virtual mode and memory protection which don't permit this. To access all physical RAM, you'll most likely need to write your own OS or a kernel driver for an existing OS.

Answer 3

You can not do this, because you have not privilege to do, when you run your code, it creates a process to run your program, and each process can only access to its address space, access to others process address space make a trap to os, and your kernel suspends works and checks your stack and your process, then it find that you did an unprivileged task, and then it kills your process
