Why not put a push button to the PWR ON pins?
i don't wonta
i don't wonta i wonta do it my way lol
no i'm thinking of using or up grading a farm to 755's but the one i have won't boot without the cable and button, was wondering if this was the norm or i'm missing something, usually i just jump green and a ground or - and they start this one won't or does anyone know where i can find the pin assignments for the k25 header for motherboard gm819 ?
The green wire trick is reserved for PSU testing.
I cringe at the idea that the power could be stuck ON with the green wire.
Wonta fried chips with dat?

yes it is and i should of elaborated a little further , i use momentary switches so each motherboard so i can start them one at a time, normal is through wol bash script that starts each at 20 second intervals.
Then the choices are pretty clear.
Use the green wire and if it fries then it's done. I would not use the green wire.
looks like it can't be run with out the i/o pannel connected
i have 10 motherboards, 2 farms running this way for the last 5 years, that is mute at this time a dell 755 motherboard it would seem needs it's front i/o board. there is a air temp sensor on it that in less hooked up stops the boot process with a air temp sensor error
do you have the pin assessment for the k25 connector on a 755 dell motherboard?
This is where I get out the Ohm meter.
Then trace which lines short out when I tap the power button. It sounds like you can do this.
As to the green wire that's good to hear it works. I wouldn't.

yea i have an i/o board and cable ordered when it gets it i will go through it and check for the power , switch and hopefully the thermal censor, i was just hoping someone knew where dell had it documented already, when i get the i/o i will post back and document what i find.
10 motherboards and not one Dell machine?
But it sounds like a server farm. Isn't this going to cost you in electricity more than what it cost for these systems?
I did something years ago and found it was cheaper to give away a boatload of Pentium 4's to move to 4 times less units but with quad core Core2 (quads.) Today I bet my old server rack could be replaced with a pair of i7 quad cores and pay off in 6 to 12 months in the reduced electric bills.
they are more for cluster computing rendering, compiling, dedicated chores, some custom software that i'm not sure could make that big of jump into the future lol
motherboards pulled and put in custom rolling racks , custom filtered cooling system, mobile , state of the art 6 years ago lol
