how to read bios date and version ?

I have been searching for API which I can use to access BIOS memory address space. I found one which works in WINDOWS 95 but not in windows NT and windows 2000. I am just wondering if there is an API which works in all three platforms win92, winnt and windows 2000. OR is there any references, resources where I can get more info about getting access to BIOS memory area using C or C++. I need some example or code that I can use to read at least BIOS date.


Thanks a lot for your help in advance.
