Bios Mods -The Best BIOS Update and Modification Source

Hi everyone,

I need to access advanced settings (specifically legacy BIOS mode) on the Lenovo Ideapad 100S-11IBY UEFU, if that is at all possible.

Alternatively, would flashing a different BIOS from a device with the exact same motherboard model work?
I haven't come across any that do use the same model yet, unfortunately.

Model: Lenovo Ideapad 100S-11IBY   (model name 80R2)
Motherboard: Aristotle 11.6
CPU: Intel Atom Z3735F

The UEFI menu only has 2 pages, and the only setting that can be changed is Secure Boot. Turning that off has no effect.

Download here: https://download.lenovo.com/consumer/mob...cn14ww.exe

Versions 11, 12 and 13 can be accessed by changing the number as well.

Any help or advice would be highly appreciated.

Cheers

P.s: .BIN file: https://www.sendspace.com/file/984fn9

I opened the latest .bin file from lenovo in UEFITool with "setup" work search i found many voices so i dont know what do now.

Some one can help me? Plus i think the bios is a InsydeH20 based one, from files on zip for flash it.
