Biostar TZ68k+ bios(old) needed ..

hii,
i need old bios for biostar TZ68K+ vr.6 mobo. I searched biostar's site but they don't have old bios. But there is a old bios which will support 22nm cpu. But i don't need that one.
I need something from 2011's which has support of 32gb ram.

Thanks in advance.


p.s : I have another thread, mods plz close that.
