Alternative Lpc Point For Duox2
« Reply #1 on: August 06, 2005, 12:55:00 PM »

Those look like 1.6 diagrams and you didn't mention the Xbox version under test. Every time the Xbox frags the lad lines go from 0 to 3.3v 3 times so it's basicly trying to load the bios 9 times during a frag. At the state when it's actually fragging the lad lines and clock shut off making the readings in that tutorial totally bogus.

If you want to test lad 3 pin 7 then check it's resistance to pin 15 of the the LPC it should be 10k ohms and so are the rest of the lad lines, at 10k. All lad lines trace back to a 10k resistor, a small one.

Are you sure you rebuilt the LPC on this 1.6 motherboard?

For 1.6 xbox's you'll need to connect some extra wires on the underside of the motherboard.
This guide should work for your chip
