It doesn't mean, that there is something wrong with your motherboard. It
just means that IRQ13 is activated when numerical errors occures in the
FPU. (I don't know why it is done in this way, while it is possible to
generate an exception by FPU. Probably it is due to compatibility with old
Intel processors (286 and lower ?) where such exceptions didn't exist)
Anyway this one interrupt line is wasted and it's associated with PC
architecture.
