I am trying to get Bios date from WinXP:

mov esi,0xFFFF5
mov edi,biosdate
mov ecx,8
repz
movsb
invoke MessageBox,HWND_DESKTOP,biosdate,_title,MB_OK

but biosdate is empty.
There is registry key that holds the bios date but everybody can change the registry and it is not certainly that this is the bios date.
I tried using simple com and it works but I need it under Windows.
Somebody knows how to do it?

Actually I tested the above code and it works under Win98. Somebody knows how to do it under WinXP/WinNT?
