Pretty sure it was a legacy award bios, but I don't if windows vista software installed the bios or the bios was flashed by the motherboard manufacturer which is lenovo at the time of production. I am looking for the stock firmware but cannot find it anywhere. As you said, it has perfectly disappeared.

I contacted them about a week ago and told them my situation. Gave them all my computer specs that I got with CPU-Z, everest diagnostics, microsoft system information, various intel tools, etc. At the end they offered me a lenovo 2.27-1.08 efi bios, which is not even the correct version. I have 2.29-1.08 installed which is the correct version. I told them I want legacy and apparently nothing is available.
Short of the deep web or hacking the bios, I am not sure what else is possible. I also edited my boot manager with dualbootpro into legacy mode with zero effect. The bios itself is the problem.
