Hello List,
This time the questions are different.
Given the following output could anyone please tell me what is wrong ?
In explicit what does that mysterious "nobody cared" message mean?
And another stupid question: should DMA for a network card be enabled before or maybe
_after_ interrupts get enabled? And... how to convert virtual address
to physical one?
