The Motherboard is made by Intel.There are two RSVP pins 1 and 2 which were put there for future processors in the 300Mhz and 333Mhz clock speed range, but the Pentium Pro socket 8 wasn't going anywhere too fast because of the Pentium II slot 1 processors and Xeon processors. Intel though did release a Overdrive chip for the slot 8 at 333Mhz with MMX. They are available on E-bay. Your other option is a slot 8 adapter that can use the 533Mhz Celeron (66Mhz Frontside Bus) made by...I forgot the manufature...it's not Evergreen Technologies,but they make something similar. The box will included software to update the bios.
