Accessing Physical memory in Windows

NTDEV
1

Dear All,

I need to read the physical memory contents during testing of some hardware devices for a PC. Is there any utility/drivern etc. that can let me do that in Win2K ?
Thanks in advance

You are going to have to be a bit more specific in describing what you are
trying to do. What sort of hardware devices? What memory?

In general the answer is that no you cannot directly access physical memory.
You can map specific regions of physical memory into virtual memory in
either a kernel of user process virtual address space. There is no driver
that performs a generic ‘read physical memory’ service.

There is something from Mark
(http://www.sysinternals.com/Information/TipsAndTrivia.html) plus parts of
what’s there at http://www.codeproject.com/system/soviet_kernel_hack.asp.

Hope you are not a hacker, soviet or not:-)

Google for “Device PhysicalMemory”, if \Device\PhysicalMemory is what you
need to access.

After 2K there are no soviets or hackers. Don’t run in current platforms.

Thanks for the info and the link. I forgot about it. It has been a while since I walked this way.
