You can find more information about the hardware used in each revision below.
History of Xbox 1.5
There has been no conclusive evidence pointing to their existence, and all 1.5 sightings to date have turned out to be 1.4 boards. They possibly never existed, but will otherwise be very rare. Production was halted and 1.4 was produced again.
While not definitive, here are some ways to help identify the revision of your Xbox.
The serial number looks like this:
- L is the production line
- NNNNNN is the number produced that week
- Y is the last digit of the production year
- WW is the number of the week
- FF is the factory code
Note, this table contradicts the previous table.
|02||Mexico||1.0 or 1.1|
|05||China||1.1 or later|
|06||Taiwan||1.2 or later|
|LNNNNNN 23WFF||1.0 or 1.1|
|LNNNNNN 33WFF||1.4 or 1.5|
There are four retail drives known to be used by Microsoft in the retail version of the console. Any Xbox DVD drive can be used in any retail Xbox.
List of Xbox DVD Drive manufacturers
- Thomson (Xbox 1.0, 1.1)
- Philips (Xbox 1.1 and above)
- Samsung (Any)
- Hitachi-LG (8050L)(mainly 1.6?)
The first manufacture is sadly also the worst of all Dvdrom drives manufactured for the original Xbox. It has a Cirrus Logic CL-CR3710-60EC-F as its main controller and a 8/3062 HD 64F3062F25 16bit H8/300H secondary samller MPU,at 25Mhz Unkown sofar if there is external flash or if its inside the Cirrus Logic IC.
A news article officially announcing Thomson to be producing the DVD drive for the original Xbox back in 20 Juli of 2000
The Samsung drive is a very popular DVDrom drive for its compatibility for most media types and better quality laser. There are 2 mayor revisions found for this manufacturer
- X00603-005 Plays CDR
- X00603-006 Wont play CDR
The DVDrom drive is using the MT1358E (MT1359E is the 360 Sata version) from Mediatek, and has a 39SF020A flashrom. If the firmware from this drive is applied to a SAMSUNG 616T or 616F PC dvd drive it will behave as a Xbox one, modified hardware will allow for tray state and eject to work.
Commodore4Eva released a hacked firmware for this drive which enables modified backups to work. There is also a "0800" firmware for this drive which allows to dump the entire SS. The firmwares are not linked here for legal reasons.
Also named: VAD6011/21 appears to have no brand or part number on its large main controller, might be Cirrus Logic based on its size and use of a Philips secondary smaller MCU. flash might be a 39SF020A from SST. The laser ribbon cable connector is different for its various revisions, a detail one must take into account when swapping controller boards.
There should be a tutorial on how to convert a PC DVD-ROM drive Pioneer 500M with the Philips firmware to be an Xbox DVD-ROM drive.
This DVD-rom drive, most commonly found in Xbox 1.6 and 1.6b is capable of reading DVD-+R, DVD-RW and CDRW media, but fails to boot most CD-R discs source: xbox-hq.com Hitachi-LG GDR-8050L DVD Drive In Xbox.
The latest manufacture for the DVDrom drive probably used a Panasonic MN103S89FDA for its main controler, appears to have no external flashrom. with this firmware and modified hardware for Eject and traystate, a LG GDR-8163B or LG DRD-8160B might act as a drop in replacement after altering either case.
On 30 January 2006 TheSpecialist posted at xboxhacker.net that he successfully flashed a Hitachi drive to boot a copied game on an unmodded xbox: breakthrough: XBOX 1 firmware hacked !
There is also an IDC Script and information about the firmware which was recovered from xboxhacker.net / old forum posts.
