Hi,
I have tested it. And my device (3c509 EtherLink3 ISA card)
worked properly with 5 and 7 IRQ
It corresponds to 5+PC_HARDWARE_IRQ_OFFSET and
7+PC_HARDWARE_IRQ_OFFSET vectors and here is
used master interrupt controller.
But it did not work with 10 and 11 IRQ (they are connected to slave
interrupt controller). Why?
Thanks in advance.
