asterisk users - Nov 2005 - Intel Desktop MotherBoards Unsuitable for DigiumBoards

Hi George,

I run an Intel D865GBF Desktop board with Digium's TDM400P with 4 FXOs
just fine.

Subject: [Asterisk-Users] Intel Desktop MotherBoards Unsuitable for
DigiumBoards

FYI:

We're trying to standardise on a tier one motherboard for the Asterisk
boxes we build for customers and thought we'd try to use a low-end Intel
Desktop Board since even a low-end Celeron has more than enough
horsepower to handle a typical 8x32 PBX.

To make a long story short, according to Intel Dealer Technical Support
(we became Intel dealers in order to get answers to our questions) there
is no Intel motherboard that permits the IRQs to be configured uniquely.

They are all hardwired and shared. This information applies to both the
Intel Desktop Board and Server Board product lines.

Please let me know if your experience differs from what I've been told
by Intel.

Otherwise, you've been warned -- Intel mobos appear to be unsuitable for
use with Digium hardware.

APIC support is chipset dependent.  My old Athlon 2600+ is offline,
so I cannot verify it, but the Athlon64 and Opteron systems are all
running with IO-APIC.  The systems are a mix of AMD, VIA and NVidia
chipsets.
