Maybe it's Socket 5, though my understanding was that Socket 5 only went up to P133. Was split rail voltage a requirement for socket 7? I don't believe it was, because socket 7 existed before MMX chips came out. I believe socket 7 boards simply provide more current to the CPU. Strangely enough, this board claims support for a 5/3.3V split rail CPU. I wonder if it's merely a typo, since no such CPU exists. Socket 7 split rail was *normally* 2.x/3.3v.
It appears that this board has support for either pipeline burst cache or traditional async chips, probably so you could migrate them from your 486 motherboard. I guess it was a pretty good idea, but if this board was anything like my M-tech "Mustang" M534F (SIS 5571), it must have been a real pile of dog shit.
