Soyo werbsite says this board can run an Athlon 1800 Palomino core. So I took out the Duron 850 Mhz that was running OK in there, set the FSB jumper to 266 MHz and watched it heat up and not boot. As far as I can see, nothing in BIOS to change as far as CPU. Firmware rev is 2CA5, I believe. Thoughts ?
