Get smbios structure
Hi..
I wanna get the smbios structure in Win32 environment (95-Xp)
I heard four methods to do this:
1. Use direct memory access. Smbios information stores from 0x0000f000, we can parse this area into useful data. But it can't be implemented with 32bits application in NT+ envirnoment because of OS's access protection.
2. Use driver in NT+ or vxd in 95/98
3. Run 16bits application
4. Use WMI
I wanna make a application to get smbios structure without driver, and it can be used at every platform. I can't use WMI because some OS have no WMI support (95/98/NT)
Can someone give me a little advice?
I have some source codes to dump bios written in assembly and dephi, but I can't use those resources in C/C++/VC++..

You don't need to write a driver to access physical memory (this question has been asked multiple times on this forum):

Thanks, Dan ..
I had tried the url you mentioned.
One is invalid and I had tested another link's sample code.
#include <windows.h>
namespace NT {extern "C" {
#include <ntddk.h>
}}
using NT::NTSTATUS;
int main(int argc, char* argv[])
{
HANDLE hSect;
WCHAR s[] = L"\\Device\\PhysicalMemory";
NT::UNICODE_STRING name = {sizeof s - sizeof (WCHAR), sizeof s, s};
NT::OBJECT_ATTRIBUTES oa = {sizeof oa, 0, &name, OBJ_CASE_INSENSITIVE, 0, 0};
NT::ZwOpenSection(&hSect, SECTION_MAP_READ, &oa);
PVOID p = MapViewOfFile(hSect, FILE_MAP_READ, 0, 0, 0x400);
return 0;
}
I could build and link successfully, but the binary can't be executed because of normal initialization error (0xc0000005)
What's wrong?
My programming envirnemnt is Win2k + VC6 + PlatformSDK + NTDDK.
Could you show me the sample codes of your own if you have?

Both URLs worked OK for me.
I remember I used physmem long time ago and didn't encounter any problems. It comes with full source code:

The sample project works smoothly.
The url is ok, that was my ISP's problem.
Thanks for your help, the code encourages me a lot.
