hiho


i installed now about 3 xbit modchips into xbox consoles, amazingly the first installation is the only one that worked correctly.

i always used the solder iron way...

the first xbox where i installed an xbit modchip had already a cheadmod installed before. i removed the cheapmod an installed the xbit and everything worked just fine out of the box.


but on the 2 other consoles i installed the xbit just as mentioned on their website. flashed the bios (tried with evox M7 an xecuter2 4977). all consoles are 1.0 or 1.1 and these two were completely new xbox consoles, straight from the store. never touched before. but the xbit never worked, the xbox always booted from the standard m$ bios.

i verified all solder points with a multimeter and all points seem to be soldered correctly (i soldered to the contact points on the front side. i checked continuity using the pogo-pins on the chip against the corresponding contact points on the back of the xbox mobo.) and i suppose that my soldering skills are rather good. wink.gif
continuity checks ok.

the dip-switches are configured correctly and i verified if the bios has been written correctly to the xbit module on the corresponding slot several times.
everything ok.


but when i try to boot the xbox it always boots from the standard micro$oft bios.

i even tried to bridge the d0 to ground (d0 to C4) so that it would ignore the on-board m$ bios, that's the way it has always worked with all my cheapmods. I hoped that it might force the xbox to use the bios from the 3rd party module (xbit in this case) but unfortunately that doesn't seem to work, i just supposed that it should work by theory. i'm not that microelectronic expert wink.gif

so, until now i didn't manage to get a single xbit modchip working on a virgin motherboard.

am i doing something wrong, am i missing something or what might be the problem ?

thanks for your support.


i can even post some pictures if you like, of the modchip installation.

Are you getting a green light on the external board? Are you using a boot disk?

i tried with several BIOSes, xecuter2, evox m7 etc.

and i used several boot CDs, slayer evox installer 2.1 and a custom evox cd that i used to install my first modded xbox, the one where i first had a cheapmod installed.

and the harddrive is still the original xbox seagate harddrive.

but the xbox never boots from the cd-r. i always get the standard xbox error message that the xbox is unable to read the disc in the dvd-rom drive, that it might be damaged blablabla.


the LED on the xbit external board glows green when i power up the xbox, so the chip should be activated. but the xbox acts exactly like if the xbit is in stealth mode.

if the xbit light is glowing green and it boots to the ms dash it sounds as though the xbit is working and you just need to get your dashboard on there. Have you tried using a bios with a colour mod so that when the bios boots the X-logo is a different colour so that you can see if the chip really is booting a bios other than the M$ one?
Also what media are you trying to boot the dashboard off?

forgot to say you can use XBTool to change the colours of the X-logo in your BIOS and then flash it to your xbit.

i tried everything, i modified the bios image and stuff, but it still doesn't work

i suppose that the boot cd is not the issue here.

when i power up the xbox i should immediately get the custom bios, when i select the xecuter2 bios i should get the XECUTER2 tag below the xbox logo instead of 'MS'

the xbit never kicks in, the xbox always boots of the onboard bios.


what i found extremly strange is the first xbox, where i had a cheapmod installed before, worked just fine after i removed completely the cheapmod and wires and installed the xbit. i installed the xbit exactly the same way in all 3 consoles. but only it only works on the xbox where the cheapmod has been installed before.

and i never flashed the TSOP or anything on the xbox where the cheapmod was installed.


very very strange...

some stupid suggestions:
1) make sure you correctly inserted the black wire harness to the black spot on each board, and the same with the yellow. many folks have screwed those up.
2) you already colored your bioses (right?) so that shouldn't be the issue
3) make sure stealth mode is OFF (dip switch #4, i'm not sure if you want it on or off)
4) did you try booting without the drives installed, and just the colored bios(es)?
5) when you flashed the xbit, did you get a "verify does match" message showing a good flash?
6) I didn't do the wire install, but did you make sure the wire harness was facing the right way, installed all the way, etc.?
i don't know what else to suggest - but i'd be interested to read the answers to the above.
Best of luck!

well

1) all wires are connected correctly
2) bios is colored
3) stealth mode is off, otherwise the LED on the external board wouldn't glow green
4) i didn't try that yet. but it did now after reading your post but unfortunately it doesn't change a thing
5) yep, verify ok
6) the wires are all soldered correctly. i even tried using the d0 above th MCPX chip and the alternative d0 on the back of the board. checked continuity and stuff, everything seems to be soldered correctly.

still doesn't work sad.gif


i guess that i'll drop the xbit and use a cheapmod instead. it doesn't have that many features but at least it works...

I am going to send in my XBIT for a replacement. When I let Diveno know of the issue, they responded,

"Sorry to here about this problem, please return the product to

Divineo UK
PO Box 137
Manchester
M22 8XA
UK


We will send you a replacement, on delivery, of your returned product.

PLEASE INCLUDE A NOTE OF WHAT ACTIONS YOU REQUIRE"

This is under the assumption you ordered from them, guess bottom line is that I have a feeling there are faulty XBIT chips out there.

Even though this looks like its resolved with my Xbox when I did a pogo-pin install and the External Xbit would powerup with the green led. I tried putting a different color bios on there too. Finally I decided to just reopener up and realign. I think that with the pogopin install you shouldn't screw down too hard because once i loosened it up just a quarter turn my chip worked.

From the 20 or 30 some attempts and reading a lot of other posts, I found the green light does NOT mean everything is aligned. I had a pro solder the thing via header and wire and the thing still did not work. They are sending me a replacement chip, which I guess I'll put up on eBay or something. Anyone in Virginia wanna buy a new XBIT?

The very first batch of xbit mod chips has a serious problem with the hid controller on teh modchip and compatibility with the MS driver. It sounds like they never tested it on any new machine and they never knew about the bug. However as far as a bad batch goes I am pretty sure that there is no such thing. I had some problems with the chip at first because apparently alligning the pogopins is not as easy as it looks. It does not matter how tight you screw it in as long as it is making a connection at all points. Actually when everything goes in place if you had screwed it tightly you will hear a click (very neat feature). Well anyway after I had to battle the mod for about a day I got it working. The green light on the externel board DOES NOT mean that everything is aligned. It simply means that your mod chip is getting power. I got x2 bios working fine but unfortunatelly the x2 bios has serious issues booting from a multi game disks without a replacement dashboard. The M7 bios would not work no matter what I change. That was quite a disappointment. Other than that the mod is nice but the company really has to do something about that hid controller and the EXTREMELY low transfer speed on the usb connector.

I think I would rather have slow speed then have corruption. I mean for a 256k file it takes max two minutes although long for usb its still not bad for the ease of use. And how often are you changing your bios where 2 minutes per 256 or 8 for a meg file is gonna really matter. When I was first installing it was bothering me cuz i kept on trying to get my box to work but finally realized i should re-align the chip.
Btw the M7 Bios worked excellently on mine no problems what so ever. I think I have a version 1.4 but im not sure.

they cant do much about the transfer spped anyway, the speed is so low because the wires going from the internal board tothe external are unshielded. However if they make them shielded the transfer speed can be increased but the wires will no longer fit out of the slots at the side of the xbox.
