Questions About Premodded XBox

Recommended Posts

Hi there,
I'm new to the og XBox world
I bought a XBox half year ago and took it apart.
I found out that it has an "Aladdin 2" modchip and as far as I understand is also TSOP modded.
It's a NTSC XBox v1.0.

My questions for you are:
Do I really need the modchip?
As far as I understand the v1.0 has a big TSOP Chip, which can be splitted into banks, if I really need different bioses.
So does this modchip anything different/special?
And why do I need different Bioses?
I just want to use this Xbox as (region free) Gaming console and maybe for XBMC.
And is there a cheap (and easy) way to get digital output?
I only got a VGA adapter with this XBox and it doesn't really work with my TV.Please login or register to see this attachment.

One reason the modchip may have been installed is because a TSOP reflash attempt failed and the console would no longer boot. 

Installation of the modchip was required to get the console working again.

It definitely could have been TSOPed as the R7D3 connection is clearly bridged but the R7R4 point, on the back of the board, obviously, can not be seen.

So very feasible ^ that explanation.

If that is the case then yes you need the modchip.

Yes, v1.0 has a 1MB TSOP but if that was messed up its now inaccessible. Please login or register to see this link. thread explains a lot and some options that may still be available.

Aladdin 2 Modchip: can't find any particular info about it but although old I'd think it does not do much more than allow you to power on the Xbox using the original BIOS or the modchip:-

Off – Tap the power button and the Xbox starts as normal with the original BIOS.
On – Press and hold power button for 1 second and the Aladdin is activated.

But that does mean you can test if it was a TSOP problem that led to the chip being fitted. If you try to boot it by tapping the power button an error or refusal to boot again points to a bad TSOP flash being the likely culprit.

You do not need different BIOS for the functionality you want. You could run BIOSChecker and see if that identifies the BIOS but if it is working and does what you want then IMHO there is no good reason to re-flash the chip.

No digital output possible without an adapter.

No VGA practical unless your TV or monitor supports Component via a VGA adapter. Some do, most don't. There is a direct VGA output Xbox mod that can be done but it requires both significant cable modding and re-flashing with a BIOS that supports VGA.

Thanks, for you responses
R7R4 on the back of the board is also bridged.
The XBox boots the same way when pressing the power button or when holding it for at least one second or by pressing the eject button or holding it for at least one second.
I've also started BiosChecker on every run and it also showed always the same.
As far as I understand it always boots into the ModChip.
I've attached to output from BiosChecker

I found a wiring diagram for this particular ModChip Please login or register to see this link. , but BT is soldered to a different location (On my XBox to ground).
So, in my understanding, BT is the reason why the XBox always boots from the modchip and if I desolder BT the XBox should boot from the TSOP.
Can I damage the XBox when trying to boot from the TSOP?

Hello,

the chips is always on because there is a wire between BT and the board ground. If you want to try onboard bios, just unsolder wire from bt or from ground. If I does not boot anymore, it would confirm that the onboard bios might be dead.

bye

Thank you for your confirmation.

I removed the wire and after the boot animation it shows "Your Xbox requires service. Please call Xbox customer support." without an error code.

Is it possible that files are missing on the hard disk or because unleashX and xbmc are installed?

It occurred to me that if the HDD is unlocked then you might very well get an error screen when trying to boot from the original BIOS if it was still MS retail.

But with the evidence of the TSOP points being bridged it is more likely KaosEngineer's  suggestion that the TSOP flash was messed up is correct.

BIOSChecker is not much help in identifying any modified BIOS. It could have been modified in the most minor way, just a change of colour or a logo removed and the MD5 hash would be completely different and not included in the BIOSchecker INI. If there is no BIOS configuration file on any of your drives then that might suggest it is not a BIOS that needs such a file and can exclude some BIOS but it won't tell you what it is.

The presence of a BIOS config file though is no indication of anything as installers like HeXEn may install such files even if they're not actually being used. The original user could have flashed any BIOS and just left old stuff behind too.

That BIOS checker program is as useful as a ashtray on the dirt bike.

You could try the 3 wire  trick and see if the onboard bios can be recovered.

Thank you guys for all your help.

First I've resoldered BT to ground and after that, I've found Clean C and E Files in this forum and loaded them to the C and E Partition on my Xbox and locked the hard drive with HeXEn. Later on I wired the modchip like on the diagram I showed you yesterday and now by just taping the power button or pressing the eject button the Xbox boots into the retail dashboard and when I press and hold the power button for some seconds the Xbox boots into UnleashedX.

Good to here and it sounds like who ever modded it could not work out how to flash the TSOP and fitted a chip.

      Have a NTSC xbox 1.0 console but live in Italy here is the 220v current,you can mod the PSU to 110v to 220v? at the moment use a step down converter and works fine.

      This is going to start out as just being copied directly over  from my thread on BitBuilt about the project.
      Please login or register to see this link.

      The xbox has some mildly odd power requirements. It uses the same 20 pin Molex MiniFit Jr connector that an ATX PSU output, however the pinout is completely different.

      As it stands, the typical solution is to use a PicoPSU, a small ATX PSU, a modify it to work with the original xbox.  PicoPSUs can be had for around $15, the power supplies for them can be had for around $10.  It's a very inexpensive solution.  Traditionally when this is done, the Power OK and Power On lines are ignored, the PSU is set to always on, and the wires are run all catywumpus to get to where they need to go.  While this solution works, it's definitely a hack, and I believe we can do better.
       
      So what are the xbox's actual power requirements?
      While I haven't actually cut up a power supply and tried to get the xbox to full load while measuring the current draw, I have a V1.1 PSU here that handily has the power requirements right on the label.
      Max Output Power: 96W
      DC Output:
      +5V -- 13.2A
      +3.3V -- 4.8A
      +12V --1.2A
      +3VSB -- 0.045A
      I hope it's safe to assume that further revisions of the xbox had similar or lower power draw.  Regardless, this seems like a good starting point.
       
      So, how do I plan to accomplish this?
      With 4x LM2678 Regulators from Texas Instruments.
      Please login or register to see this link.
      Why 4 regulators for 3 voltages?
      The LM2678 is a 5A regulator. I need 13.2A on the 5V line.  Having looked at the specs for the PicoPSUs that seem to work just fine, they're rated for 8A on the 5V line. This leads me to believe that 10A should suffice, so I'll need two regulators for 5V.
      I'll also need a 12V regulator, as I plan to run this off of an easily obtainable laptop power supply rather than needing to source an 8A 12V supply.
      I will also be designing a smaller footprint alternative that runs off of 12v for when space is of the highest concern.  I'll likely also break down the xbox's power requirements even further at some point to see if I can't design a PSU that allows for aggressive trimming, but that's much further down the road.
      --------------------------------------------

      I've designed the first iteration of the 24v board, it's 60*32mm. Now that it's done, I don't like it for a variety of reasons. I'm going to try again, putting the low profile components on the backside of the board and the tall components on the topside of it. Maybe I'll be able to squish it down a bit more in the process.
      --------------------------------------------

      There, that's a little better.
      27.5*49.25 mm
      --------------------------------------------
      Oh, hey, I worked on this a bit.
      I ditched the 12v regulator and changed it to 12v in. I also had to source different inductors, which are sadly larger, so the whole board got a couple of mm wider in the process.

      26.5mm*57.2mm

      I think I'm gonna actually order this one, and see if it works.
      --------------------------------------------
      I've since looked at the most recent revision and noticed a couple of flaws in it. I've repaired those flaws, and I'm gonna sleep on it again, look at it with fresh eyes tomorrow, and probably order it.
