Opened A Xbox To Find A Hitachi-lg Dvdrom, **MERGED TOPICS** Options

@patx

can you confirm that the ready function works fine? just wondering cause you used hfmdrv.

I have been watching this for the last few days and now got the drive working.
but i have used a different tray in point, but my drive board is a bit messed up after lots of soldering.

big thanks to all involved

YES everything works fine exept that i don't have the"open" & "close" mention in EVOX. ( but "init","checking","games","video"... all appers) and for my part i soldered a 1k ohm resistor on all wires exept for EJECT.

it is very good.
this drive works !!!!!!!!!!

Just a little adjustment to patx instruction. I found out that when using HFMDRV as ready point, the tray will not close when you power off your xbox. When using HFM as ready, the tray will close automatically as you power off the xbox with the tray left open. This is how it should be. Now everythings work great except for status in evox keep saying "init" when it is actually opened. If anyone has any idea how to fix that, we would have a 100% working drive. If not, im cool with it. Btw, I put 1K resistor for all my connection.

I'm still not really sure why my points are working in one drive but not in an(y)other, but there are some differences between the two drives so I thought I'd post this information here in case anyone can provide further insight. The working drive works perfectly, ie. it's indistinguishable from an 8050L -- all the right status reports come up exactly as with an 8050L drive, the tray auto-closes on power off etc.

Firstly, the working drive is older. The label on the case is stamped March 2004 whereas the other drive is January 2005. I found two markings on each circuit board that seem to be version numbers of some sort. One is on the component side under the audio output connector and the master/slave/cable select jumper. On the older, working drive this one reads 6870H-344AA. On the newer drive it's the same except it ends in AB instead of AA. The other version/revision number is on the other side of the board in the corner where there's sort of a gap at the end of all the connectors and jumpers.. On the working drive it reads
JD4 (GDR-8163B)
2004/02-02
On the newer drive the first line is the same but the second line is 2004/01-08.

Next, the firmware on each drive is slightly different. The working drive was flashed using my IDE flasher and the firmware as I extracted it from my 8050L. The newer drive was flashed with the .EXE from xbins. After extracting the ROM image from this .EXE I discovered that it does not exactly match the image I extracted from my 8050L. The difference would appear on the face of it to be unimportant, but I can't be sure. My image has 8KB of FF bytes from offset 0x4000 to 0x5FFF. The .EXE image has a repeating pattern 99 9B 9F 08. This pattern seems to be used as "filler" in other areas in both images (maybe it's some kind of jump instruction or NOP).

Finally, the working drive is the one I've been using for all my experimentation, so it's possible that it has been damaged in some way or that earlier experiments have altered its function in some way.

I'm kind of tempted to hook up the IDE flasher to one of these newer drives and flash my ROM image to it, but it's a pain to do and maybe the act of doing this has some side-effect I'm not aware of, so I'm not sure it would really prove anything unless the experiment fails.

XBoXMan,

Yes, use HFM, as its the cleaned signal of the HFMDRV. The small component nearby is the buffer for this trace.

Also, xboxman, did you try an original xbox dvd, and it comes up ok in eVox? According to the french tutorial, it comes up, but those pics are blurry! (Dude, use a tripod!)

[truBB]

wenid,
I did get my IDE-flasher from germany, but really havn't played with it much yet. I got in my linux box, compiled ctflasher, a little bumpy, but got it to work. I'm a bit unfamiliar in the next step. Did you unsolder the chip then place it into the flasher? Or did you solder a million wires? This is of course, for future reference, as this firmware has already been pulled.

I did this mod tonight and everything but the "Init" function is working. It skips right to game. Which really isn't a problem. I have tried orginals and backups both are working fine. I used the hfm point also closing on power off is that much closer to an orginal drive.

I didn't try the orignal xbox drive as I don't have one

Hi all
A short tut has been submitted to tutorial on xboxscene this should help with converting lg 8163b to work on an xbox. This should fix problems with TRin, TRout & Cd_Rdy. Keep up the good work!

My tray closes when I power off my console ... but If it works with HFM, than i guess its better to use it !!!

[truBB]

I finally got my hands on one of thes LG xdrives. Points per wenid, confirmed.

Basically,

uC (pin 49) ==== 1K (r227)====pin 5 (tray_out)
uC (pin 50) ==== 1K (r228)====pin 6 (ready)
uC (pin 52) ==== 1K (r229)====pin 8 (serial)
uC (pin 65) ==== 1K (r230)====pin 7 (tray_in)


Must be because the circuit is different. I will have to look into it further and compare the drives.

[XBoXMan]

@truBB

does that mean you got it working 100% or you're just saying the points were correctly traced?

[rutgerius]

Yeah It works great. I only had the problem that my lead in and lead out wires were switched. Maybe I there is a mix up somewhere, but I think I messed it up. When I switched them all was working perfectly 100%
Look at the result...
