I wired my Xecuter 2.2 Lite+, and have gotten it to frag, but can't get it to load the bios.
I want to make sure that my connection to the LPC points is good.
I have very little experience using a multimeter, so if anyone could help me with step by step instructions in plain english, I'd be very greatful.
I have the following selections on my Multimeter:OffDCV
(Some weird symbol)DCA
Unreal7000 told me the following:
|Put the multimeter on Ohms, try any range. Then put the black or negative to the metal part of the xbox. Then touch the red or positive to the piece on the mod-chip. If the meter jumps when you touch them both, then it is aligned properlly. |
Then I responded with:
|I want to be 100% sure I'm understanding you correctly. |
By metal part of the xbox, what do you mean? The case?
What do you mean by the peice on the mod-chip? Each point where I've soldered the wires to?
Days later, I got plenty of irrelevent replys, but none that actually answered my question. So, please. I'm desperate. Does anybody know this???

Are you people incapible of answering such a question?
How did you people ever check your LPC points?
I'll buy a round for anyone who answers!

Ohms measures resistance between two points. If you get a readback of infinity, it means the circuit is closed, if you get any value readback other than infinity it means that there is current flowing between those two points. By grounding one probe (touching it to the metal casing of your xbox - I would try the screw you hooked your modchip to (or perhaps the Lite+ doesn't hook to the screw, I can't remember) either way, one of the screws holding the mobo down, and the other probe to the wire that is connected to the LPC point you should be able to see if there is current flows between those two points.
So that if you are to touch a probe (it doesn't matter, BTW, black or red) to the ground point and then the other probe directly to the LPC point you should, if your multimeter is setup correctly, get some sort of reading for resistance (measured in ohms). However, instead of measuring it directly on the LPC point, touch the pogo-pin of the modchip that is touching the LPC point. If there is good connection between the pogo-pin, the LPC and ground you will get some reading for resistance as well. If the reading is infinity then the circuit is closed and the connection is bad.
If your xbox if fragging then it cannot find a bios to boot. We can rule out d0 as being the culprit as your onboard ms bios has been successfully grounded out, that means that either your LPC points are not aligned correctly or you don't have a bios on your modchip. Which brings me to my next question, which website did you buy your modchip from?
Hope that helps.
Oh, and I'll that we "we people" don't check our LPC points, because we solder our chips in...

Sorry if my sarcasim wasn't obvious enough. I didn't mean that seriously.
And I do have it wired in. I realized the error of using the solderless option a tad too late, but I have wired it instead.
So before I go out and buy that thing to flash my chip, I'd like to make absolutly sure that I did a good job soldering. So thanks again Hal, for all your help.
(And GLaCiERDC, shhh. I've been trying to get this simple question answered for days. I wouldn't call that super fast, would you?)

not at all "fast" but you word yourself like if we owe you and if you dont get your help then we're crappy people or something, thats all.

Well, like I said, I was trying to be sarcastic. Sorry if it didn't come off as such.

A programmer is cheaper than a multimeter and if you've soldered your chip to your LPC points the problem is probably the bios.
Say, you don't have a v1.5 xbox do you??
Dec 17 2003, 04:00 AM
I've got a multimeter already, so I figgured I might as well do that first. Besides, I don't think I can wait for a programmer
Read the sig! (1.0, baby!)
Dec 17 2003, 04:03 AM
If you have access to another modded xbox you can hotswap the chip and flash it that way.
And I did read your sig! Just thought I'd ask.
Dec 17 2003, 04:10 AM
I wish I did!
Everyone around me with an Xbox has been waiting to see how my modding turns out. So I'm the guinea pig
BTW... I got my chip from system-mods.com
Any negitive history with them?
Dec 17 2003, 04:16 AM
No, system-mods is good. I've never heard any negative feedback for them. And I have to ask, did you make sure and put the switch in the right location for your version xbox? Other than a faulty connection to the LPC that's all I can think of. If you did, then I'd just check it with the multimeter and make sure your solder points are shorting any other points out...
Dec 17 2003, 04:23 AM
Yeah, it's all good there
Make sure my solder points are shorting any other points out?
I assume you mean make sure they aren't shorting any other points out. But how could they, besides excess solder (which there isin't any)
Dec 17 2003, 04:30 AM
excess solder, bare wires touching each other, bare wires contacting ground...
Dec 17 2003, 05:34 AM
Nope, that's all good.
I guess I'll have to check it after I get back from my trip.
Thanks so much!

When did you get your mod? Are you sure you didn't get a 2.3? If so you have to wire in your power from the usb. Otherwise, I would take your multimeter and turn it to a continuity check and check from your mod to a test point (like the d0 point) on the MB - not just the solder points.
