You can download an example program from the old forum:

But as I noted in your "I need help" thread, this will not work under Windows 2000 or XP.

Thank you for your reply. But as u said Interrupt 15h, Function E820h is not supported under Windows 2000/XP.So i dont think that this will help.

Microsoft Windows stores the size of the memory in offset 040:0413h but i am not very sure that it works all the time.I hope that i gave you some help.

Sorry i didnt mention that you must get a word size and convert the hex value to decimal which will give you the memory size in MB.
