Getting E820 memory map from Windows

Is there a Win32 API or documented ddk function to get E820 memory map information? I am trying to avoid a hack but use documented API to get to this information. Thanks.

You can use WMI and the Device APIs to get the actual reserved memory ranges, which is more accurate than the BIOS-reported ones. If you really want the BIOS one, you'll have to write a device driver.
