The match that I found from a search engine points it to a Supergrace motherboard, Model SG-AKT133KMSSM3(B)
And there is a BIOS link here for the bios:

But the date is the same as the one you have.
Could you double check your board for a similar model # silk screened on the surface, I want to make sure we have the right one here...
