this is a xenon jp board, i soldiered all the cables, check with multimeter for bridges/cold soldiers. the system turns on fine but when i plug the lpt cable into my computer it does not turn on at all. i am using the "new xenon pinouts" i have re done all the wired and check twice. i am using 2 switching diods for jtag, none for lpt and the 5 330 resisters on lpt.. anyone have any clue?

its not supposed to turn on with the lpt cable plugged into the pc. you read/write the nand wilst the 360 is powered off but has the psu plugged in. shouldnt the lpt cable have 100 ohm resistors on there and a diode?

Yep - if the LPT is plugged into your PC, then the 360 won't boot. You should be using (dependant on your PC LPT port), 100ohm resistors + switching diode for LPT, and Switching diodes for the JTAG wiring.

the free360 tutorial put the lpt diod as optional, once i added the diod it worked perfectly.

new problem, i need to recover my dvd key, how do i get it to boot xell...when i hold x with a controller in the back usb poer i just get a black screen and the lights flash. do i have to have a dvd drive actualy pluged infor this?

also im using VGA, the system boots normally but cant figure out how to get to xell
