Just spotted one on ebay. I think it's a very interesting 440BX mobo since it comes with 3 ISA slots instead of 2. However, I went to the website and could not find the manual.

Anyone ever used this model before? What is the highest PIII CPU supported by this mobo? Where else could I find the mobo manual?

And how difficult it is to tinker with the mobo without manual? 🙁 Say, for the purpose of underclocking? Or does 440BX motherboards share (relatively) generic jumper layout, so it shouldn't be difficult to tinker without manual?
