This is an apples and oranges comparison, and there is no reason for us
to expect it to work any differently. The 'real' slot on the motherboard
is PCI Express; the riser cards have bridge chips on them. Dell
obviously chose to implement the PCI-X riser in a different way than the
PCI-E riser, and the result is different behavior.
This goes back to my original point: the IRQ assignment behavior has
nothing to do with the manufacturer/type/style of the card, and
everything to do with the implementation of PCI, IRQs, BIOS and other
bits by the system manufacturer.
I suppose... and everything you've said makes sence. My point is, if
manufacturers are going to start making systems like this, then, in my
opinion, Digium perhaps should consider making PCI-e cards. We've noticed
this behaviour on Dell, IBM, and several other servers.
At any rate... as you state I do believe it is a MOBO/BioS thing... but you
also said you have a 2950 in the office in which you are not having this IRQ
issue. I'm really interested to see what your tech guys have to say (I
sent you a separate e-mail from my work account). Believe me, I would
*love* to see the Digium cards work in the Dell servers.....but as it stands
right now, they aren't for many people.
I guess what I'm saying is, Digium can stand there all day and blame the
system makers, and I will stand here along side Digium and blame the system
makers... but the system makers seem to not care. Sangoma has a PCI-e card
that works fine. What is my only option if I wish to continue selling PBX
systems? Exactly...and if others go this way it is bad for Digium's bottom
line.
