lspci and interrupts at the bottom. yes, we have apic.

The EN12000 is equipped with a PCI riser like the one here: http://www.tranquilpc-shop.co.uk/acatalog/info%5f2%2ehtml Please also see http://www.tranquilpc-shop.co.uk/acatalog/PCI_Risers.html and http://www.tranquilpc.co.uk/support/Files/TPC014/Tranquil%20Riser.pdf for info about how the riser works.

Ah, this sounds interesting. Any pointers about hwo to do this?

I will give the change a try.
