I have a 2.2 lite and an Xbox with a Thomson drive. The Xbox is well over a year old and I don't understand why my bios hasn't become too old to play the new games. I can play everything no problem on my xbox. Maybe I am confused, do people only have problems when they are putting games on their hard drive as opposed to just backing up on DVD? Also, can anyone explain why I have the option to flash my bios on my Evox menu? And finally, when I look what bios it says in settings in Evox it says "unknown" Why?

From my understanding.."BIOS" is pronounced "bye-ose", lol...It is an acronym for basic input/output system. The BIOS is a built-in software that determines what a computer can do without accessing programs from a disk.

On a XBOX, the BIOS contains all the code required to control a USB device, display screen, disk drives, hard drives, and a number of miscellaneous functions.

So you see Eggbert, All XBOX games/Apps are coded to run exclusivly on the XBOX and take advantage of the XBOX bios and physical hardware only. They cannot do anything more than what the bios and physical hardware of the system will allow. Understand? So thats why your games still run no matter what version bios you have. The xecuter bios is just a microsoft bios that is re-coded to allow "other options" it was never intended to do. Backups/mp3's/un-signed code/Run games from the hard drive. I hope I didn't confuse you on that one.. I had a beer and it was sorta confusing for me.. Next..

A XBOX game has a boot flag on the disk. I believe some games have a DVD check to see if it's being ran from the DVD drive or not.. So when the game starts and see's it isn't being ran from a DVD drive it locks. Not all games are like this. SO some need to be patched. This is where the BIOS thing comes in. DVD boot flag's "can" be coded into the bios
and then a patched XBE game file isn't needed. It would just run no problem. Also my evo-x dash says the same thing about a unknown bios. Not sure what thats all about.. Probably not implemented..

The "flash bios" is just what it says.. You can flash your bios within evo-x. I hear some people had trouble with this option or a bug in some versions? some didn't. I would stick with the xecuter bios manager.

You said to take a stab at this one so I did.. I hope I haven't confused you or made things worse. To my knowledge that's how it works..

if you talk to kevin on screensavers(tech tv) he explains that some games wont copy to your hard drive, cos your bios needs updating
course
games from the HARD DRIVE and from the disc, are 2 different issues

Actually they use the same file structure. Whats different about a DVD game being executed from a DVD drive versus a hard drive other than speed and the media flag?

Aint got a clue, like egg (who I chat to on msn a lot) Im confused when htese programs say "you need to update your bios if the games wont copy anymore" etc
leo laporte on the show said "I have a few games that wont copy to my hdd anymore" kevin dude said "you need to update the bios"
I found it odd myself. But usually he gives some pretty kewl tips.
Maybe he misunderstood I dunno.
Only problems I have had Ive overcome and they havent been bios issues , just game sizes, iso creation etc.
I still have the 4977 bios on a x2 2.2. (lite)
Soooo I dunno matey, maybe it was a "copyright on tv " thing hehe

I bought a game that would not copy to the hard drive. It was MTX Mototrax.. Some files would not copy no matter what I used. It backed up to a DVD just fine though. I posted about it in the forums and no one has answered..So maybe it's just me.. I tried everything.

That's hillarious you mentioned that because I can't even get that damn game to FTP all the way.

Thats the problem I am talking about. Thanks for confirming it again for me Egg. You can FTP them, but only after renaming them to something smaller,copying them over,and then renaming them back. I haven't confirmed this myself. A trusted friend said it worked. I'm to lazy so I just backed it up on a DVD and play it from there.

afaik (and i could be wrong), bioses need to be updated in case there are any internal hardware changes (e.g. modchip, switches)so that the box can adapt to the new component/s and its capabilities. as to what kevin said, it could also be a case of some chips having the innate ability to do things that have only recently been brought out into the open (as in, "hey, our chip can do that, too!! we just need to update the bios.")

as for why your bios shows up as "unknown", you need to include the md5 hash of your bios to your ini file e.g. for 4977:

ROM = "X2 4977",0x92987e26edd5833921c9b0e539ea091e
ROM = "X2 4977 Darker Blue",0xd612e7ee1f58a76298d67f39246a8d1c
ROM = "X2 4977 Blue",0xc4c2dcb8714c3a0d6cdb40213172f6e7
ROM = "X2 4977 Blue noani",0xc4c2dcb8714c3a0d6cdb40213172f6e7
ROM = "X2 4977 Gray",0x860746a3d229c8851e1f98d45fad546b
ROM = "X2 4977 Green",0xe853ca313e1e2d57418cf1759ae73f6b
ROM = "X2 4977 Green noani",0xe853ca313e1e2d57418cf1759ae73f6b
ROM = "X2 4977 Orange",0x9dbf36b33590b073e1b5f71f36438b12
ROM = "X2 4977 Purple",0x5888771b9c6308ea5433151cd277a033
ROM = "X2 4977 Red",0x00e4ac5dee193d2bcd14910c89732103
ROM = "X2 4977 Red/red noani",0xaacae34cf419053714b305cf8bdbd129

should show up the next time you reboot.
