Someone mentioned earlier (I can't find the message now) that they had a motherboard that allowed you to change IRQ assignments in BIOS. Does anyone happen to know how to identify motherboards that can do this? I'm going to put together a new machine now and I'm having trouble picking a motherboard for it (ordering from Dell or other online vendor is not an option, since I need this in the next couple days). This is to provide another avenue for avoiding IRQ conflicts with the Digium TDM400Ps. Thanks! Jen

I have built several servers with intel and abit boards using this chipset Always use a good UPS rather than a surge protector outlet strip. You can get an APC brand with USB signalling for as little as $50. It works with linux. That means the linux server will see when the battery is low, prepare itself for shutdown and then tell the APC to kill its output. When power returns the APC will turn outpput back on and the linux server boots gracefully. When buying CPU I usually go with the "retail boxed" instead of OEM. It doesn't cost much more. It includes the cooler along with a good warranty. If it fails you get a new cooler along with the new chip. Obviously they can't try to get out of warranty replacement based on the cooler selection if it was their choice in the first place. I stopped using athlons when I could no longer get boards with the AMD chipset(supports ECC). You can probably still get boards designed for dual athlon. I asked AMD why and they told me the 760 chipset for single athlon was no longer in production. It seems the average consumer doesn't appreciate higher quality features enough. It's too bad because I always liked AMD stuff. When I needed fast reliable chips for some specialized processors I designed it was AMD that gave me the first samples and they always gave the purchasing people good pricing for production needs. I'm only mentioning this because there has been some banter about AMD vs. Intel here. If the right motherboards were available for single socket 7 servers I would have stayed with them. Their service is excellent. They give me free overnight shipping and 2 weeks to send in the defective part.
Get ye to a used computer store and get one of these: http://cgi.ebay.com/Compaq-Deskpro-EN-Desktop-550MHZ-128MB-6-4GB_W0QQitemZ52 33796857QQcategoryZ51114QQrdZ1QQcmdZViewItem Your original post said you were trying to get a small office going. This would be suitable for a dozen or so users as long as you weren't transcoding. When you boot it, hit F10 and go into the BIOS. In Advanced Setup > PCI you can set any PCI card to any IRQ you want. A TDM card shows up as "Unknown Intel network controller". I set my TDM22 to IRQ 11 and disabled the onboard audio, parallell, etc to give plenty of free IRQ's. I set the Intel NIC to IRQ 7, for example, the same IRQ as the parallel port. On mine, zttest yields 100% about 70% of the time, no echo, and with 3 extensions going, top says CPU at ~10%. It took me a couple hours total to get it going first time with Asterisk@Home and that includes terminating the cat5 and setting up a telemarketer honeypot.

Any Deskpro EN has that feature from the P-166's up until Carlygate. It's an extremely common used PC, since there were a bajillion EN's leased and then liquidated. Note: You need Celeron class or higher to work with a TDM card, a PII's bus is not *quite* PCI 2.2 compliant and the card won't be recognized. -----Original Message----- From: jennyw [mailto:jennyw@dangerousideas.com] Sent: Wednesday, August 24, 2005 11:40 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [Asterisk-Users] Re: Motherboards and IRQs Colin Anderson wrote:> Get ye to a used computer store and get one of these: > >http://cgi.ebay.com/Compaq-Deskpro-EN-Desktop-550MHZ-128MB-6-4GB_W0QQitemZ52> 33796857QQcategoryZ51114QQrdZ1QQcmdZViewItem[...]> cat5 and setting up a telemarketer honeypot.

Trouble is, I'm leaving for an out of town trip early next week and want to get things settled before then. So I was hoping to drop by the computer store tomorrow and pick up what I need, so was hoping to find the name of a board that could assign IRQs that would be popular enough that it'd likely be in stock ...
