110 well, your board is able to boot. So the bios is able to access spdrom to read
111 the memory settings. This is done via smbus.
112 If you use sensors, you are probably using isa/lipc bus to access the chip.
113 And even if you don't. Do you have a ps/2 keyboard? The keyboard controller
114 sits in the same superio chip as the sensors.
