this is good stuff. I just got my 1.6 today and ordered an X3. I'm definitely going to use the resistor as I don't want to ruin this new toy. One question though: I was comparing the image originally posted (top of the very first post in this thread) with the URL=http://http://www.teamxecuter.com/x3/tutorials/x3pin16.htm]X3 install tutorial for 1.6 pinheader[/URL](had to save the original 'resistor install' image local, and flip it upside down to match the two up), and I noticed that there is an extra LPC connection on the resistor install pic. If you are looking at the resistor install image "non-flipped" its in the second row five down and runs almost straight to the left. Can anyone tell me what this connection is? Does not having this connection affect the X3 install?  |

| QUOTE (pedro @ Nov 18 2004, 04:27 PM) | I recently did an install for a guy using an x2.6 on a v1.6 xbox.
do I need to have the guy bring his xbox back in so I can do this to it?
and all I do is solder the resistor and cut the trace?
sounds easy enough. |
Its completely up to you whether you want to bring the xbox back and add this extra mod - but I would definately recommend you do it on any future installs. Yes soldering the resistor and cutting a trace is very easy!
| QUOTE (gnelson) | | I am planning on buying a modchip for a new 1.6 box. I was looking at X3, Xenium Ice or SmartXX - leaning toward Xenium Ice. Do any/all of these chips have the same problem that is described in this post? |
Unfortunately I don't have any of these chips, hopefully someone will post the results of measuring LFRAME voltage while the chip is running. I will update this thread if I find info on these chips.
| QUOTE (Exige_) | Great research, this will definitely save many XBoxes . I love my 1.0.
EDIT: However, as this is a great method, I do remember reading an older manual from SmartXX that seemed to draw current and ground it while simultaneously completing the same result. It seems that have the current withdrawal featured in this new device that you can order from them for the bottom side of the 1.6 motherboard. |
Im not quite sure what you are trying to say here. Grounding LFRAME either directly or through the modchip is the problem. The PCB to fit on the bottom of the 1.6 is just an easier method than using wires - it has nothing to do with this mod and doesn't effect the current flow problem.
| QUOTE (Exige_) | | However, I'm sure you have already, but be sure to contact Team SmartXX and see what they think on your experiment. They seem to be the more intelligent of the modchip developing teams. I ahve a SmartXX, and it's easy to tell they worked hard and made a truely amazing piece of hardware and an astounding package of software. |
No I havn't contacted them - hopefully they have already dealt with this problem on existing chips by releasing LFRAME after booting. I'm waiting for someone with a Smartxx to confirm if this is the case or not.

Pin 9 on the LPC (which you are referring to in that long description  ) is 3.3V. The wire is required to power some modchips, but the X3 doesn't require it. |

Very, very interesting.
I have recently purchase a batch of Aladdin XT lites. I have wired my first install for an "always on" config by grounding the D0 ( Lframe ) on a 1.6 xbox. So, if I get what you're saying correctly, by installing a 680 ohm resistor between said points in the diagram ( in lieu of a direct ground ), I can alleviate worries about prematurely overdriving the xboxes D0 output?
Is there a wattage rating of the resistor? Do you have a part number for the surface mount component? If the surface mount resistor isn't available, can I use a standard resistor? I'd like to safe gaurd my handiwork, by taking this precaution. TIA!
One other point....are the lpc rebuild pcbs ( Smartxx, Aladdin, ect, ect.... )addressing this problem?

For an "always on" installation you can just cut the track on the top of the motherboard, and connect the LFRAME point shown in the diagram to ground (you don't need to worry about the resistor at all). The resistor is there to allow the xbox to work with the mod on or off without any problems.
1/8 W (0.125 W) or higher is fine (actual power used is 0.02W).
It doesn't matter if you use a standard resistor or surface mount - I just had surface mount available and it does a clean tidy job. A 1/4 W standard resistor can be installed, just cut the wire short, bend it into shape and solder the ends to the vias shown.
The rebuild PCBs are just an easier method to install a modchip into a v1.6 - they are exactly the same as using wires.

This is extremely good info. Over on the cheapmod forum, there's an effort being made by a couple scene members to correct the awful install diagrams put out by xenochip, for the Aladdin XT/XT lite mod chips. This would be valuable info to include in the "always on" diagrams. Just to clarify, the cut is made as shown in your picture ( on the topside of the motherboard ), is the Lframe point that is to be grounded, the point labeled in the yellow box "LFRAME TO MODCHIP"? Something like this?:  Or are we talking about the Lframe connection on the bottom of the motherboard, that's part of the LPC rebuild? See arrow...

Not through any fault of catdog2, I'm just picturing a 14 year old kid taking a steak knife to his data tracks..
