-------------------------------------------
You might check
"http://www.webopedia.com/quick_ref/IRQnumbers.asp";
IRQ 7 is normally a parallel port IRQ - say like a printer.
A 8259A IC "http://www.ctv.es/pckits/tISA.html controls that
port.
A RTL8139(A,B,C) is a ethernet IC which is normally IRQ
10/11 as set by a PCI bus controller.
