Need help with new setup w/Shuttle AK11

I am currently trying to upgrade an old celeron 333 system to a brand new Tbird 950 with a Shuttle AK11 as the mainboard.

I pulled the old mobo, added a couple of new IDE devices, put in the new mobo, mounted the chip, slapped on a heatsink and fan, fired it all up...

Nothing.

So I unplug things, and start trying to add them one at a time. The only interesting result which was produced was when I unplugged all IDE, PCI, and AGP devices, and the memory modules which were installed. The motherboard dutifully beeped every 2-3 seconds, presumably to complain that I had left out the RAM. Plugged in the RAM, beeps go away. Unplugged the RAM, beeps don't return(?!)

What is going on here? I'm assuming this complete lack of functionality could be either an error on my part. But the inconsistancy of that "you unplugged the RAM, stupid" beep troubles me. Perhaps a broken board, or something else? Which front panel connectors are necessary to get this thing to turn on? Again, I am assuming I need only the power switch to be connected to get some sort of elementary response from the system. Do I need to have any IDE devices plugged in (assuming no). What is the minimum wattage I can get away with from the power supply? If I am using a 235, and it needs a 250+, will these inconsistancies be the sort of problems I will see? Could the chip be improperly seated and, again, produce these inconsistant errors? I'm truly at a loss, and my instincts tell me this board is simply hosed, but I want to exhaust every possibility before I admit defeat.

Thanks for any feedback.
 
Bump, again.

Is this really a stumper? Maybe I should simplify the question...If I were providing insufficient power to a mobo (I've never tried it before) could it look like the problems I am describing, or would it just appear to be working properly, and over time I would notice an inherant instability?
 
You need at least 300 Watts for an Athlon system, and more depending on peripherals (aka, at least 400 for a well stocked XP system).
 
Well, I realize that is partially true, which is to say, AMD recommends at least a 250 watt power supply for their systems, and the AK 31 mobo and system I have running at home is rock solid and running off a 250 watt power supply.

But, hypothetically, if I were running an AK 11 on a 235 watt power supply, would I simply not get any output (remember, only the mobo, processor, memory modules and a PCI graphics adapter are plugged in)? What would the likely failure look like? I don't want to run around buying unnecessary parts if this mobo is just broken...
 
I have built two systems based on the AK11 both gave me a little trouble at first. I was all my fault, I hadn't checked the jumper settings. Both of the ones I got had been shipped with the 'clear cmos' jumper on the 'clear cmos' setting! setting them to 'normal' and waiting about 5 minutes fixed the problem.

also, if it's not clear then clear it. the two systems I built were using a 133mhz bus CPU. so the mobos being set to use a bus at that speed by default wasn't a problem. however, a tbird 950 wouldn't boot @ 9.5x133 at default voltage.

gooood luck!
