Re: Interrupts - electrical question

>>>>>>>>>>>>>>>>>>>>>>>>>>
We are developing a PCI carrier board (not for Windows) with 4 slots. 
It is advantageous for us to segregate interrupts on a per slot basis 
(even in the case of multi-function cards).
     
Is there any reason, why I couldn't tie all four interrupts (INTA#, INTB#, 
INTC#, INTD#) from a given PCI slot together to form a single interrupt. 
Thus, I would have four interrupts, one from each slot.

     This is OK on a motherboard, because the BIOS will know that you did 
     this and assign interrupts correctly.  This routing will cause 
     problems if it is done on a plug-in extender sort of device (requiring 
     a P2P bridge) becuase the BIOS won't know the specifics of your device 
     and will assume the standard interrupt routing as defined in the P2P 
     bridge spec.
