    not bad information but i would have liked to see some kind of real world performance using openmosix.. a single x box on its own as a pc is slow but stick 2-4 together using open mosix could make a reasonably good machine and still be pretty cheap Reply

    The rule followed in the article for the -j option, "number of proccessors + 1", overlooked the logical proccessors of the Xeon's Hyperthreading.. -j should have then been something around 5 instead of 3 Reply

    Simply compiling on the Opteron and Xeon with the same number of threads as the full cluster would have illustraighted a difference.

    More testing should have gone into finding how many threads was the ideal number for the given platforms.

    Aikouka, can't you just use one of those "HD Loader" type programs WITHOUT a modchip?
    I'd be all for modding my PS/2 if I thought I could actually do something useful with it, like stream audio/video from a PC or a ReplayTV or something.

    Halz: what should it have been?

    23, yes, you can still do just about anything. I know with the software mod that I use, I've been having problems getting the original MS Dash to load up, but I've gotten around that using other programs for the original dashboard's functionality (dvd etc).

    You know, you can also replace the HDD with just a software mod, and it's not that hard. So, if you don't want to hardware mod and want more space, you can still put in a bigger HDD. As much as some people don't like the XBOX, in my opinion, it's probably the best console to mod.

    24, 2) Modchips also allow hdd loading if you have the PS2 HDD (using HDDLoader.) Also, it lets the warez'ers download and play games on the PS2 that they don't really own.

    1) what we really need is a usb-based tv tuner that actually works. That would be excellent for adding functionality both to XBoxen as cheap PVRs (though I'd still just use XBMC to stream from my ReplayTV, most of the time), but also would be great for iMacs. I'm sure if someone came up with a decent open architecture design, the community would come up with drivers for both types of systems.

    2) what are modchips for PS2s useful for, other than playing import games? Especially with the new PS2s having no drive (is there still a header on the new board style to add one back?)

    3) did I miss the obligatory dnetc test? You gotta do that, you know.

    I don't even own an Xbox, but reading this article has me reaching for my wallet...

    But first, I want to get this straight - I can mod the Xbox and still use XLink, right? I doubt I'd get a Live subscription anyway, but it'd be nice to have that option possible.

    Ideally I'd like to throw a bigger hard drive in there and then run XBMC, without losing the normal XBox capabilities.

    So if I can do that, I'm goin' to the store this weekend... :)

    The compile options for the Opteron and Xeon were starving the CPUs; the number of jobs (-j) was no where near optimal. Reply

    I was just wondering if you will do a test with mental ray on the cluster (I think you mentioned something about Mental Ray in the article). It would be really interesting to see the results of that since me and a couple of friends got modded X-Boxes and I have a 3dsMax6 license (Mental Ray is included). Reply

    You might want to look at the "mini-cluster" project (http://www.mini-itx.com/projects/cluster/) when planning/designing/building your EPIA cluster. It's a 12-node (originally 6) cluster developed by Glen Gardner, and appears to be the same size or a little smaller than a stack of an equal number of XBOXes. Of course, the frame is custom built and the hardware is exposed to the world. Reply

    I can say that I love having a modded xbox, because the capabilities are so much greater. As discussed earlier, a software mod can be a great way to do it (although it usually requires a game unless you want to take your HDD out, which is NOT a fun method unless you love swapping IDE cables.)

    It's also good to note that you should be careful when modding these or even make a backup of the hdd on your system, because things can go wrong, and if you like to fiddle with things, then your chances will be a lot higher. I know at one point I was stuck in error 16 and had to pull the HDD out and unlock it using the IDE swap method.

    Are there plans for an article on modding something such as the PS2? I just recently tried a no-solder modchip in the PS2, and it doesn't seem to be going along too well. Maybe it's time for a flip-top.

    If anyone wants their xbox motherboards upgraded to 128 megabytes of memory, I can do it

    I'm UK based and use BRAND NEW samsung memory chips

    I can upgrade your existing motherboards, sell you ready upgraded boards, or even just the chips!

    if one of the anandtech team wants their xboxes upgraded i'll happily do it at cost, please contact me to discuss

    First, XBox live banning....

    Basically this is how it used to work. When your on live it does a hash of your bios. A mod replaces your bios. If you bios is not the retail ms bios the serial (eeprom) is blacklisted. NOW since halo2 has been released it appears that MS has changed a while bunch of shit on us. Preliminary information indicates that MS is banning by hard drive serial+model numbers, xbox serial, and flagging the gamertag as 'potential pirate'. Thus to unban the xbox both a new hdd and eeprom are needed. Then you must cancel and create a new xbox live account. There are more details about how it all works but bottom line is we dont know how it works now. They can throw new stuff at us anytime now. Rumors are flying that hdd capacities are being scanned as well. For all intents and perposes xbox + modded xbox's do not mix.

    Yes there is a PS1 emu for xbox. That said xbox DVD drives do not read cd-r (or retail ps1 games) Therefor all games must be transfered to the xbox hdd in bin/cue or iso format

    When comparing mods remember, the mod contains no modded bios stuff. They are useless in them selves. You will need to aquire a modded bios for your xbox (online, free). What this means is that every mod can contain the same bios's. Therefor they all contain the same base features (mostly booting unsigned code). Hardware features and support is where you want to base your decision on. If you want cheap + no manufacterer support there are 10$ solutions around for you(enabled/disables with power button). If you want support with a mod with a few extra hardware features (2 bios's, external switch) that'll cost around 30-40. Fancy Shamcy lcd support, 8 bios banks, blah blah blah fancy external thing thoes are up to 75ish. But in the end they all allow you to run the same software on the xbox.

    After seeing Halo 2, it makes me wonder if they really need Pixel Shader 2.0. Its pretty cool that I can play old games on the XBOx through emulators though but i wanna see when the next XBOX kicks off before spending $200. Reply
  • ViRGE - Wednesday, November 10, 2004 - link

    #12, probably not. The Xbox's GPU is a GeForce 4 class GPU - the lack of Pixel Shader 2.0 features can really be limiting. Reply
  • euph - Wednesday, November 10, 2004 - link

    is there any way to use the gpu for the pov-ray rendering? Reply

    Little quote that sums up the SmartXX XBL saga:

    Q: just bought a Smart XX mod and I still don't know if i'll be able to play xbox live so please somebody tell me if i'll be able to play it.
    A: There is no easy way to answer this question. First of all, it all depends on circumstance. Have you upgraded your hard drive? Has your Xbox ever been banned before? And, for newbs, are you thinking about playing on live while using a bios from the chip.

    If you answered yes to any of these questions you've won a lifetime ban from Microsoft!


    Sleep time :) And i don't even use XBL :D

    Yes the xbox has a PS1 emulator, only one that i know of. Its called "PCSXbox". Good place for emulator info: http://xport.xbox-scene.com/ , obviosuly a subsection of xbox-scene.

    And before anyone asks, no there are none for the PS2 (nor will there ever be).

    I'm not 100% sure about the SmartXX, as i have the well known Xecuter 2.3b chip which has DIP switches mountable on the outsode of the xbox so that youc an disable it in order to play X-Box live and whatnot.

    From what i've just read over on the forums at xbox-scene, SmartXX is fully X-BoX Live compliant. You simply (as you say Kris) boot back into the MS BIOS. This can be done by turning the xbox on by pressing the EJECT button. To enable the modchip, turn on with the POWER button. (source: http://forums.xbox-scene.com/index.php?showtopic=3...

    #3, you said there is mulators for n64 and down. Is there an emulator for PSone games? would love to be able to play FF7 again Reply
  • KristopherKubicki - Wednesday, November 10, 2004 - link

    Jeff7181: I think with the SmartXX chip you can actually boot back into the normal MS BIOS and have no problems with X-Link and such. If you install Linux on the last 2 unpartitioned GB of your 10GB drive, your XBOX should basically have no idea that the machine is modded at all.

    LotoBak, ukDave, am I correct on that statement?

    Oh and Jeff, i believe many mod chips have the facility to simply turn them off with a flick of a switch, so you can continue to use XBOX Live. But as LotoBak says, there is the free X-Link service available too. Reply

    http://www.xbox-scene.com is really the only place to go for XBOX related discussion, tutorials, really anything you need to know that isn't covered in this article.

    I bought a bodged XBOX mod from someone in the UK, got it professionally fixed and re-modded. It now has a 120GB disk for all my games, its connected to my LAN. With the excellent XBMC i can play literally any media file from any PC over the network, be it standard files such as MP3's or AVI's, or images such as .bins/cue's.

    Well worth looking into if you have an XBOX that is currently un-modded.

    Also, /me wants 8 XBOX's :D Although, those 'leccy costs, eek!

    I've been thinking about modding mine to use to play video over the network... but I don't want to lose normal Xbox (and Xbox Live) functionality. Wish that was covered here, but I guess it's not really a "mod your Xbox" article as much as it's a "mod an Xbox to make a cheap PC" article. Reply

    Nice guys... besides your linking problem

    Knowing a little more about the xbox scene a few things your might consider...

    1) Mods go for as cheap as 10USD retail.
    2) Software exploiting the xbox is always an option which results in a 'free' modchip
    3) http://tutorials.xbox-scene.com to learn about most anything
    4) XBMC dvd menu support is comming!
    5) XBMC irc channel on irc.efnet.info #xbmc
    6) Online gaming is free through Xlink www.teamxlink.com
    7) Emulators for n64 and 'down' are available
    8) This is the cheapest htpc with 480p 720 and 1080i available
    9) xbmc supports many formats
    Audio : wav, aac, ac3, mp3, flac, ra, vorbis
    Video : ogg avi mkv rm, mov containers
    Codec : xivd, divx, mpeg2, mpeg1, quicktime, realvideo and realaudio (limited) and many others. The video engine is based apon mplayer open source project

    Networking :
    Shares :Supports ccx, samba (windows file sharing), and replaytv shares.
    Streaming : Supports a multitude of video and audio streaming formats. webradio is included which has a 'channel' browser for online shoutcast streams. There is also a apple movie trailer browser.

    Scripting :
    XBMC has python scripting language implimented so its open to many possibilities

    XBMC does have some rough edges but it is maturing quickly. If you are interested in contributing to the project check out www.xboxmediacenter.com and the 'XBMC' project on sourceforge

    Feel free to ask questions about xbox stuff here... ill watch it for a while
