[asterisk-users] Re: Dell PowerEdge 2950 Sharing NIC IRQ with Digium Card

[Eric "ManxPower" Wieling]

None of these mention APIC, so I assume they are written about machines 
without APIC support.  I'm sure what you claim was true in 1998, but is 
not true on any modern PC.

Here are some links about APIC and IO-APIC.

MANY other types of cards have issue with sharing IRQs.  This seems to 
be especially common with audio cards.
