Either it is or it isn't defective.........

If you mean "it reads some discs but not others", then you may need to try different media, or a different burner. If it will read an original game disc then it is basically working, and DVD-R burned at 4x or slower is universally readable on Xbox DVD drives, so try that.

If that doesn't work then you could use FTP to copy the contents of the boot disc to a temporary folder on the E partition on your Xbox, and run it from there.

Checked it. It's defective - it doesn't even read original discs. Just making weird noises.

OK, so you have to use one of the other options. smile.gif

You can TSOP flash without a game - just solder the points, then boot your Xbox into the softmod, and use Evox to flash your new BIOS to the TSOP chip.

The TSOP and a modchip are just holders for the BIOS. It's the BIOS that allows you to run unsigned code.

I'd seriously recommend that you try the Frosty/xman954 VGA solution first, just to confirm that your wiring is correct.

I second this. I was unaware that you had no working DVD-Rom.

This is what I did so far:

1. Soldered the VGA port after JaredC01's diagaram/guide to the motherboard (LM1881 circuit and wires correctly isolated)
2. Softmodded the Xbox with XboxHdm 2.2 USB & ndure 3.1
3. Extracted the files from FrostyTheSnowman's and Xman954's VGA Boot Disc v1.0 and transferred them to my box through FTP
4. Wrote down the steps to get to the boot disc xbe
5. Connected the pins 9 + 10 and 13 +14 for VGA mode
6. Started the box and repeated the steps for getting into the vga boot thingy

Result:
No Success... What did I do wrong? Like I said: I even get a signal (even if it's green tinted) on bootup but after that nada.....

OK, here we go <takes deep breath>:

First off, instead of connecting together lines 9 to 10 and 13 to 14 (mode 1+3), you want to connect lines 11 to 12 and 13 to 14 (mode 2+3). This should get you a centimeter further (progress is progress, nonetheless).

Secondly, One thing that I have noticed after I reviewed the entire topic is that you stated above that after you built your adapter, you could only get an image (although green), on one of at least 2 tested monitors. This tells me 2 things.

1. The monitor that you were able to get the green image on actually supports sync on green, and that your LM1881 chip is not necessary with this monitor.

2. It is possible that your LM1881 circuit is still not built correctly. The fact that you got no image at all on the other monitor means that it does not support a Sync on Green signal (and is possibly at this point, exactly what your xbox is still outputting) and thus, your LM1881 is either not connected correctly, was damaged during this project, or was Dead On Arrival.

Note: There is a very slim possibility that this monitor (the one that cannot get a signal at all) is just very picky in that is does not like the non-standard VGA signal that the LM1881 produces AND ALSO does not support S.o.G. This leaves very small (but existent) doubt to second point (2), however I am 85% sure that point 2 is true.

Lol, tried that with the pins a few seconds before you posted and now I got a signal in XBMC!!! It's a bit dark but it's just a matter of configuration.
Just have to try emulators and games...

Thanks for your help!!!

If I run into another problem I'll report it here. wink.gif

Now, do you get a signal with either monitor that you tested?

By now I only have tested one monitor (which works). I'll test my HDTV and the other CRT monitor tomorrow.
(It's 12pm right now on my side)

Is that working with the softmod and with the Frosty/xman954 VGA BIOS?

No, just the softmod. Maybe it has got something to do with the x2config.ini (from the VGA boot disc ) which I put on E: ?

No, the VGA part is hard coded in the BIOS, the config just tells the BIOS where to boot the dash from.

Hm... Okay. Then I really don't have a clue why it works now all of a sudden.

Because the softmod VGA patch needs the video output to be in mode 2+3. smile.gif
