This is my first post in this forum, so please excuse if I unintentionally break any forum rules.

I am a windows Kernel programmer, and I need to find out from Windows, whether my underlying BIOS id EFI or legacy. I have used RW-everything to look at hte various structures, but till now I haven't been able to identify the specific EFI tag. The proposed solution should work with most (if not all) BIOS manufactures.
