Not had any time at all to work on this - so we knocked this together last night to give budding coders something to have a crack at

pls no questions - if you now what you are doing all your answers will be on this page

This hasn't really been tested and may need adjusting - but it basically controls d0 and a15 similar to the matrix for flashing your tsop

TBH i dont know why this hasnt been released to the scene before now as the code is really really simple

CODE

some info that this code was based on (found on xboxhacker.net)

Programming the Onboard TSOP using a X2PRO or X2LITE.
This can be done and has been done on 1.0 boxes.

1) Connect TSOP Write lines (See matrix instructions)
2) Ground A15 (T1 on the matrix instructions)
3) Program X2Pro with EvoxMatrixTSOP bios
4) Turn power on and after 1/2 second turn DIP switch 4 off
5) Wait for EvolutionX to come up
6) Remove A15 Ground
7) Use EvolutionX to Flash a 1 meg bios to TSOP

Make sure your Evox xbe is named and placed somewhere that the EvoxMatrixTSOP bios can find it. I used a CD-RW with Slayer's 2.0 disk and Flashed 4974 onto the TSOP.

Look at the TSOP Flash Matrix Instructions floating around for pin locations etc.

This works with both the PRO and LITE but ONLY on 1.0 boxes until a EvoxMatrixTSOP bios is released for 1.1.

BTW, After you remove the A15 ground but before you flash the TSOP, if you use EvolutionX to backup your Box, you will have a copy of the orignal bios from your box. But you must do steps 1-6 first before you do the backup or you will just backup the X2.

*bump*

can a mod make this sticky - i think you'll find its wanted by a lot of ppl

indeed it is. thanks, Uber!

nice job Ubergeek, you are truly a god!, thx for this wonderful info

Edit: N00b Question - How do i use this code? I would like to flash the TSOP.

Very nice indeed. One of my xboxs wont boot to evox tho lol
Im building the milksop so i can program it without a modchip.
But this does give me something to play with and test

Veryu very cool.

I counted about 30 errors in the code which need to be fixed before assembling. Has anyone had a crack at it yet?

I still keep getting errors with MPASM for some reason.
I haven't used it since upgrade. Perhaps there is a bug.
Will look into it.

You really don'y need the PIC or the Code to do this. Just follow the directions below the code. Turning the X2 off after you turn on the Xbox is not that hard to do. It just takes a few times before you learn when to do it. After that, its easy to repeat.

Just remember to use a boot CD or have Evox on your hard drive in a place the EvoxMatrixTSOP bios can find it. Slayer's 2.0 disk works great for this, Just flash the TSOP with the Bios on his disk, then you can copy a different Bios to your harddrive and flash that.

It says to turn off switch 4 on X2 Pro, can i aussume i can just take the On/Off jumper off the X2 Lite and uflash it with the X2 4976.02?

You just take the jumper off the Lite. You need to create a 1 meg bios image with 4 copies of 4976.02 in it. This is what I have programed in my TSOP and it works great.

The Lite is a little scary to use, you must program it with the EvoxMatrixTSOP bios to do this. If you can't get Evox to Boot (it may take a few tries to get the timing down.) then you may not beable to reprogram the Lite back to a work Bios. You can't run a box with the MatrixTSOP bios. It is only used to flash the TSOP.

But it does work. Several people have used this method with a Lite and Flashed the TSOP.

This is all good if you have code on your tsop..,but what if there is no code on the onboard tsop? Ive tried this on my 1.0 that I flashed with emigah and hosed. I forgot to disable 15,21. so I bought the x2 . Box fires up with any bios but the Matrix_tsop. flip dip number 4 ...1/2 second into boot it goes into the on/off cycle mode with red /green flashing button. Timed the switch 4 a hundred times. Am I just missing something? Oh and I barowed a buddies Matrix and the whole proccess acted exactly the same. also I was doing the t1 to ground. Any help is apriciated:)

No That is what I figured Thanks:)
