Lenovo IdeaPad Firmware (BIOS) Versions

I realize that this may not be the best place to post this, however I hope that these can help others.
I had found most of these by trial-and-error, by manually specifying files from Lenovo's servers.

I'll be glad for any additions to the list.

If the firmware version is listed, but not linked, that means that I am aware of that firmware's location, however I have not yet managed to find the filename.
