first of all, sorry for my english

now, i have a problem.
i just received an old laptop, "white" laptop (some company bought the computer's parts and assemble it).
i scaned my computer with Sisoft Sandra, because i wanted to know all about the computer that i received.
sandra show me a Warning that i should fix (attached link)

i set the bios to DEFAULT settings (there isn't optimised or such thing) but sandra still show me this Warning.
so, i figured, that i have to update my bios (sandra told me to do that also).
BUT-
i don't know the manufacturer of the motherboard...
even the EVEREST software not recognized my motherboard.
here is some information that i succeded to find.
