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. |
