Hi everybody,

i was told that i should ask my question here, cause here are some more
skilled people :)

What i want to do is to read as much hardware information as possible
from the actual system.

What i already implemented is this:

- read descriptors from CPU
- CPUID stuff
- Registry-Information (Bios, IDs etc.)
- Harddrive

I got structure SYSTEM_INFO and HW_PROFILE_INFOA.

What i want to get is this:

- Is there 3D-Support for the graphics Adapter (just a yes or no)
- HDD Vendor
- CDROM Vendor
- Temperatures of cpu, hdd, mainboad...
- RAM-Timings
- MBR and Partition Table

Everything in pure C. Not c++ or c# sorry,. i just learned C and want to
stick with it.

If anybody can help me i would really appreciate it. But i hope you know
that if i get just a Name like GetAllHwInfos() i dont know how to use it
So if there are any codesamples i would please you to post them.

Thanks a lot!!

sandiego.

There's a heck of a lot stuff available from WMI classes
(e.g. Win32_PhysicalMedia).

You'll need to use COM to access the WMI classes. Unfortunately,
nearly every guide to using COM is oriented toward C++ or Visual
Basic. It's very hard to find information on accessing COM from
straight C.

Fortunately, I've already done the legwork, and found an excellent
set of articles by Jeff Glatt entitled "COM in plain C". You can
find the first one at http://www.codeproject.com/com/com_in_c1.aspx -
google for "Jeff Glatt" "COM in plain C" for links to the whole series.

I think you could do most of those low level stuff using BIOS.Try
finding a library that can call BIOS functions,interrupt calls rather.
INT 13h reads raw disk(HDD). MBR will be in the first sector of the
hard disk that is the first 512 bytes of the disk.The partition table
follows the MBR.

See MSDN, it's about the same code in C or C++ :

You can test creation of a D3D Device

IOCTL_STORAGE_QUERY_PROPERTY or
IOCTL_SCSI_GET_INQUIRY_DATA or IOCTL_SCSI_PASS_THROUGH

By reading the SMBIOS Tables with, e.g., WmiQueryAllData()

> - MBR and Partition Table

CreateFile()-ReadFile() + IOCTL_DISK_GET_DRIVE_LAYOUT_EX
